Proven ways to use sawdust in the country. Using sawdust for fertilizer How to process fresh sawdust for quick decay

Should I use sawdust in the country? Many people ask this question, let's find out the opinion of those who used sawdust in practice.

Question: How useful or not useful are sawdust on the site? Where and how can they be used? Or maybe it's better not to use it at all?

We have several bags of sawdust. A neighbor asked us and scattered it around her site. The mother-in-law wants to fall asleep with them under raspberries - I don’t know if this is right or not?

O.: I have a bad opinion on them. They acidify the soil terribly. And shed urea, it's still bad.
Raspberries didn’t even gain leaves, and the lawn didn’t grow at all, or rather, terrible shreds. And she fell asleep, and that she just didn’t do it. All that season, where there were sawdust, down the drain.

O.: The paths between the beds are covered with sawdust, they are watered all summer to rot, in the spring they are closed up in the beds, something like that.

O.: Sawdust perfectly loosens the soil and serves as an excellent mulch. But! If you do not have blueberries, rhododendrons or needles that require acidic soils, then add dolomite flour along with sawdust to alkalize the soil.

O.: Sawdust can be taken free of charge at wood sawing enterprises. In Berdsk I know what they give out, my brother traveled like that, collecting sawdust to cover the roof of the bathhouse.
Sawdust should be used carefully, because, on the one hand, sawdust loosens the soil, and on the other hand, it acidifies it very much.
Therefore, our parents and grandmothers advised us to pour sawdust on the paths so that there was less dirt, and in the fall, add slaked lime to the soil, simply scattering it around the garden, in the spring the whole thing is dug up.
Sawdust is also used in the processing of onions, kerosene is diluted in water and sawdust is added there, a little infused and then scattered over the onion bed - not very dense, of course.

O.: Sawdust actually greatly increases the acidity. Together with the ashes, I pour them into the beds and dig them up, they neutralize each other, otherwise I have solid clay in my garden.

O.: Girls, I don’t advise using sawdust anywhere in the garden, because of them a wireworm appears, which begins to devour everything, and it’s very difficult to get it out. where I sprinkled sawdust.

O.: One year she poured sawdust into the aisle of strawberries ... Then I had to cut it down, they were so caked over the winter that they took on a crust. And weeds grow very well on them.

O.: And we have been using sawdust for 3 years in a row. My husband has his own sawmill. I sprinkle all the paths between the beds, the grass grows much less, and sometimes I also sprinkle under the bushes, it’s better, of course, not to sprinkle fresh. No worms or animals. Everything looks great and beautiful, like a snowball on the ground. And in the spring we dig it all up with a motor cultivator.

O.: And we also love sawdust, only we have them with chicken manure. Sawdust och. loosen the soil, and in order not to acidify, you must first fill a bucket of sawdust with water. And I do warm bed under cucumbers - in the center of the garden I bury sawdust with chicken droppings, and cucumbers around the edges, and they always grow very good. well.

O.: Girls, you all know. Cons: sawdust acidifies the soil, sawdust removes nitrogen from the soil. Now we change minuses to pluses.
It acidifies - it means that you need to alkalize, mix with ash, and where they were used, add fluffy lime in the fall (now a special lime deoxidizer is sold in garden stores, by the way, it’s great to use it when growing clematis).
It takes nitrogen - it means that we pour it not dry, but soak it in a bucket with urea, and even better with calcium nitrate - this is nitrogen + calcium, which also alkalizes (deoxidizes the soil).
I take a bucket, dry mix the sawdust with ash and pour 2-3 tablespoons of calcium nitrate into a bucket of water. I use it as a mulch for both raspberries and strawberries.
Thus, any minus can be changed to a plus.

Here you can see that the strawberries are mulched with sawdust, they are gray from the ashes, in the fall of 2012 they were fresh, straight from the sawmill. Then I can show which berries will grow with these "sour" sawdust.
Yes, conifers, hydrangeas, rhododendron, blueberries generally say "thank you" for sawdust mulch.

O.: For the 101st time I sing a hymn to sawdust, well, and to any other organic matter to boot. This time I photographed the obligatory sawdust companions when mulching.
I remind you:

• ash and lime for leaching, so that the soil does not acidify when sawdust is used,
• urea (calcium nitrate) so that sawdust decomposes faster and does not take nitrogen from the soil,
• water to dissolve the urea, and it is evenly soaked in fertilizer,
• Sawdust to make the earth lighter, plumper, looser.

As a result, we draw the following conclusion: sawdust can be used, but correctly. To benefit from them, you must follow the rules described above for making.

Advantages:

• the weed disappears;
• soil moisture is maintained;
• insect protection;
• the soil remains loose;

Sawdust for the garden: the use, benefits and harms of sawdust. There is still no consensus on the use of sawdust in a private plot. For novice gardeners, this technology is of great interest. Experienced gardeners refuse sawdust because of the negative experience of use. In fact, wood chips have a number of positive properties that can provide a good result. However, it should be applied with a certain degree of caution, following certain rules.

With the help of sawdust, the fertile layer of the earth becomes more loose and airy. Such soils do not form a crust that is harmful to plants, which makes it possible to reduce the amount of loosening. Sawdust can also be used as a fertilizer. As a result of proper preparation of the material, high-quality humus will be formed, which is similar to more expensive manure. In winter, mulch from wood shavings protects the roots of plants from freezing, in the summer, it allows you to keep moisture in the soil.

It is interesting! Useful properties of sawdust appear only in combination with fertilizers or after 10 years of being in a compost heap.

During this period, bacteria appear on the surface of the wood chips, which saturate the wood with minerals. In its pure form, sawdust is used to fill the tracks. This allows you to reduce the risk of the spread of weeds and gives accuracy to the entire site.

The negative consequences of using wood waste include:

• Increasing the acidity of the soil;
• Yield reduction due to nitrogen leaching.

You can find out the acidity of the earth on the site with the help of tests with litter papers, which are purchased in specialized garden shops.

To neutralize the effect of acid, sawdust is mixed with alkali-containing substances:

• dolomite flour;
• crushed chalk;
• lime or lime-oxidant;
• wood or peat ash.

Fertilizers are also used for these purposes, such as superphosphate, potassium chloride, sodium or calcium nitrate, potassium sulfate.

When using alkalis, you should follow some rules. For example, fertilizers are added to a mixture of lime and dolomite flour, which include boron and manganese in their composition. A solution of calcium nitrate (urea) helps prevent a lack of nitrogen.

Options for using sawdust in the garden

Milling

Wood chips are often used as a base for mulching. This operation is carried out at the beginning of summer, when moisture is actively evaporated. As a material, a rotted sawdust is chosen. If this is not observed, use a fresh haircut. Before the procedure, it undergoes special processing.

Method for preparing mulch from fresh sawdust

It will take 3 buckets of wood waste, 10 liters of water and 200 grams of urea. The shavings are laid out on a plastic film, fertilizer is added and evenly watered. Then the procedures are repeated. The construction is covered with polyethylene and left for 14 days, crushing it with stones. Sawdust is usually laid in the passages between the beds, mixing with ash. At the end of the summer season, wood waste is dug up together with the ground.

Carrots, garlic, onions, beets, turnips need a protective powder with sawdust. The procedures are carried out after the dive, when the landings have reached a height of 5–7 cm. Vegetable crops grow in a thin layer of a few centimeters. Cucumber bushes are best sprinkled with substrate along the perimeter around the stem.
Sawdust will look especially good in raspberries and under strawberry and strawberry bushes. The fruits as a result of mulching will be clean, not rotten. In addition, such processing will help perennials survive the winter. Sprinkling under the bushes is done when the seedlings have already taken root and gained a height of more than 7 cm.

To achieve the maximum effect, experts recommend combining chips from different types of trees. Most crops are suitable for waste of deciduous trees, with the exception of oak. For lovers of "sour environment" - tomatoes, cucumbers, carrots, as well as strawberries - you should pick up sawdust of coniferous species. This haircut practically does not tolerate pathogenic microbes, which eliminates the risk of infection of plants.

It will have an excellent effect on the state of the soil and pre-winter mulching. The use of sawdust in autumn is slightly different from the spring procedure. During this period, it is necessary to mix the shavings with compost and peat, only after that spread on the beds. In the spring, it remains to carry out shallow digging or simply loosen the soil with harrows.

fertilizer

Expensive manure will become more accessible if you mix it with sawdust. For a cubic meter of wood chips, 10 kg of bird droppings and 100 kg of cow manure will be required. At the same time, it should be taken into account that the overturned shavings are connected only with overturned manure, fresh - with fresh. This improves the quality of the compost. Instead of manure, you can use mullein, urea, or a solution of bird droppings.

Fertilizer is prepared throughout the year from the beginning of summer. Before laying a compost heap, sawdust is moistened with water or slurry. Ordinary earth will not be superfluous here (at the rate of 2 - 3 buckets per cubic meter of sawdust). As needed, the compost is poured with water, grass, hay, kitchen waste are added to it. The top pile is covered with polyethylene, leaving small pores for heat exchange and ventilation.

Here are a few recipes for such fertilizers.

Wood and ash:

• 200 kg sawdust;
• 50 l of water;
• 10 kg of ash;
• urea, saturated with nitrogen (up to 47%) 2.5 kg per pile;
• up to 100 kg of food waste, grass.

Grass and shavings are laid in layers, ash is added and a pile of urea dissolved in water is poured. The compost is covered with polyethylene organics (on soils poor in microelements):

• 200 kg haircut;
• 100 kg of freshly cut grass;
• 50 kg of cow manure;
• 30 kg of organic waste;
• Humates (1 drop per 100 liters of water).
• a bucket of wood chips;
• 40 grams of ammonium nitrate;
• 30 grams of granulated superphosphate;
• a glass of slaked lime;
• 10 grams of calcium chloride.

The substrate is infused for two weeks. Then, when digging, the beds are added to the soil. Fertilize the soil in the amount of 2 - 3 buckets per 1 square meter of land. This procedure contributes to the natural loosening of the soil.

If sawdust was stored near abandoned forest areas, they should also be pre-composted. In order for the heap to warm up to at least 60 degrees of heat, it is poured with hot water and covered with polyethylene. This temperature allows you to destroy the seeds of weeds.

Growing seeds in wood shavings

Sawdust serves as a favorable environment for growing rascada. This method is used only when nutrients are present in the seed. If the plant is not transferred to the ground in time, it will die.

For seed germination, only overripe sawdust from deciduous trees is used. The moistened shavings are poured into a container in a thin layer, after which the planting material is laid out on them. Then they add fertilizer to the tank and sprinkle it with another layer of wood chips. The container is placed in an open plastic bag and hidden in a warm place. After the emergence of seedlings, the seedling is transferred to a cooler place, the film is removed and sawdust is sprinkled with a layer of earth of about 0.5 cm. With the appearance of the first leaf, the plants are planted in the ground in a separate pot. Any seeds are grown in this way.

Early potatoes early

Wood chips are also used to prepare seed potatoes. Two weeks before the tubers are planted in the ground, the box is filled with a 10-centimeter layer of sawdust moistened with water. On top of the sprouts, the popped potato tubers (early varieties) are laid up.

After this, the seed material is sprinkled with another layer of sawdust (2–3 cm). The entire period of preparing potatoes is very important to maintain the moisture content of sawdust and the temperature is not higher than 20 degrees. When the height of the shoots reaches 6–8 cm, the tubers are watered with a solution of fertilizers, planted in holes and completely covered with earth. Above the plot is covered with straw or hay; in case of frost - with polyethylene.

How to insulate plants with wood chips

The simplest method is when sawdust is filled with plastic bags, and then they cover the root system of plants with sawdust. Garlic tolerates cold well under damp coniferous sawdust - they provide heat, but also protect crops from diseases and pests.

As a more reliable option, experienced gardeners choose a wooden box without a bottom. It is placed above the plant, covered with sawdust and covered with a film. On top of the box, you can sprinkle with a layer of earth. Plants such as roses, clematis and grapes are left to winter in the place of growth. For protection, the shoots are bent to the ground and covered with a layer of sawdust. It is better to cover the plants with a shaving in late autumn, then the risk of rodents appearing in it will be significantly lower.

A thick layer of wood waste at the bottom of the landing pit will help provide the root system with thermal insulation.

Use of sawdust in closed ground

In greenhouses and greenhouses, sawdust acts as a biofuel. They can be combined with both manure and decayed plants. As a result of such a joint effect, the soil warms up faster, and the plantings absorb useful substances better. In addition, the speed of their pereppevaniya increases, and the compost turns out to be more airy and nutritious. It is possible to introduce wood shavings into the soil of a greenhouse both in autumn and in spring. In the presence of fresh organic matter, fresh sawdust is used, otherwise, only overripe waste.

In autumn, it makes sense to cover the ridges with a layer of straw or cut grass, and at the beginning of spring work, add fresh manure and fresh sawdust mixed with lime. Then plant waste is added to the resulting mass. The soil is covered with straw and a layer of earth with spiced ash and mineral fertilizers. In order for the soil to warm up, the ridges are poured with boiling water or covered with an airtight film.

Formation of high beds

With the help of the overturned sawdust, it is possible to increase the height of the ridge. For this, large trenches with a depth of up to 25 cm are dug around the proposed place of its placement. The bottom of the pit is covered with the remains of straw and covered with a mixture of sawdust, alkali and urea. A layer of leaves is laid on top, and then covered with the previously deposited earth.

So that the earth does not crumble along the edges, a barrier is built around it from cut grass, straw or layers of turf (it must be laid with its roots outside). The sides of the ridge are covered with a film to reduce evaporation. The remaining shavings are distributed between the beds. In the future, it is used to fertilize plants. Cucumber, squash and pumpkin seedlings and young plants actively grow on the formed multilayer ridges.

Other applications sawdust

From juniper sawdust you can prepare a fragrance for the cabinet.

Small waste woodworking absorbs water well, therefore, suitable for storing vegetables in the cellar.

With the help of wood shavings, it is easy to insulate the attic floor or the floors of the first floor. For this, the material is mixed with lime and cement, and then water is added. Instead of cement, crushed clay is often used. Only before performing construction work, stones should be removed from it. Any operations with mortars containing small wood chips require preliminary laying of waterproofing. This is due to the fact that sawdust absorbs moisture well.

Video: the use of sawdust in other areas

High-quality fuel is obtained from the shavings. For pressing briquettes at home, a manual machine is used, equipped with a form for filling wood chips. The finished product is dried on the street. Such briquettes are inferior to factory products in terms of heat transfer, since they have a small density due to low pressure during pressing. However, this method of obtaining economical fuel has found wide application among owners with large stocks of wood shavings.

Sawdust can also be used as bedding for pets. In this case, the haircut performs two functions:

1. heater;
2. hygiene products (absorb slurry, waste).

Fruit tree waste contains less resin. It is advisable to dry the pine wood chips first. But from nut sawdust in horses, inflammation of the hooves can occur.

If it is necessary to make the earth loose, use sawdust for the garden, the benefits and harms of which have been studied by experienced gardeners. But it is not recommended to use fresh sawdust. First they need to be prepared. To do this, urea or mullein infusion is added to wood chips, covered with polyethylene, and then stirred from time to time to speed up the process of overheating.

After a couple of weeks, the shavings are ready to be used as fertilizer. Much has been written in the reviews about the benefits or dangers of sawdust in the garden. Experienced summer residents claim that they take nitrogen from the soil, and therefore from plants. They say that you should not use fresh sawdust in the garden, as the plantings will begin to wither.

The benefits of sawdust in the garden

Plants need loose soil to thrive. The addition of rotted sawdust makes the earth a favorable environment for planting garden plants, the roots of which receive a sufficient amount of moisture and oxygen. The use of sawdust allows you to get rid of the crust in the dry season.

They contain a large amount of fiber, essential oils and active substances. The material is successfully used to eliminate soil moisture. To do this, ditches are dug in the aisle and sawdust mixed with lime is poured. Their regular use improves the composition of the soil, reduces the number of weeds, and increases productivity.

What is their secret and how do they work?

They form a natural ecosystem for plants in the garden. It is important to use sawdust that has not been chemically treated or contaminated. Otherwise, they will become a real poison for horticultural crops. If rotted sawdust is used as mulch at the beginning of summer, then by the end of the season, as a result of loosening and the activity of earthworms, they will mix with the soil.

A thick layer of sawdust spread over the surface of the earth during the rainy season prevents moisture from evaporating from the soil surface. This negatively affects the state of fruit and berry crops.

Basic rules for the use of sawdust

Wood shavings are great for mulching the soil. They are sprinkled with a thick layer after planting seedlings.

Advantages:

• the weed disappears;
• soil moisture is maintained;
• insect protection;
• the soil remains loose;
• favorable conditions for the growth of bacteria.

Mulching

Do you need sawdust for the garden in the fall? Everyone is trying to figure out their benefits and harms. As a rule, the soil is mulched for the winter. To do this, fresh sawdust is mixed with peat or manure and scattered on the beds. During the winter, the wood decomposes and becomes a nutritious substance. In the spring they dig or loosen the soil.

High warm beds

The benefits and harms of sawdust for the garden should be studied by every summer resident. How to make multilayer high beds in the bottom of the plot? For such purposes, it is convenient to use sawdust. The top layer of fertile soil is removed. They build a side, cover it with a film to preserve moisture in the garden. A trench is formed and filled with straw, hay or grass. Further, sawdust soaked in urea is placed on top of this, then a layer of organic residues is placed and everything is completed with a fertile layer of earth.

Mulch for strawberries

Do coniferous sawdust in the garden bring benefit or harm? Sawdust, used as mulch under strawberry bushes, protects them from contact with the soil. Thanks to them, the berries are protected from the effects of gray rot. For this purpose, fresh coniferous shavings treated with urea are used. Mulch is applied in the fall to protect the strawberries from freezing and create a barrier to many weeds. Weevil is repelled by pine sawdust in the garden, the benefits or harms of which are learned by practical experience.

Sawdust in a greenhouse and greenhouse

Sawdust is a useful fertilizer for soil in a greenhouse. They are sprinkled with plant residues and manure, which warm up in the spring and quickly overheat. The air permeability of the soil increases, it becomes loose and nutritious. In autumn, straw, mowed grass and tops are laid out on the garden bed.

In the spring, fresh manure is added and sprinkled with lime and sawdust, mixed with a pitchfork. Then lay the soil mixed with ash and mineral fertilizers. To increase the speed of heating, pour boiling water.

Sawdust for early potato harvest

So, why do we need sawdust for the garden? What are their benefits and harms? The use of sawdust helps speed up the potato harvest. Choose tubers of early varieties and germinate in the light. At the bottom of the boxes, 10 cm of sawdust is poured, tubers with sprouts are laid out and sprinkled with moistened sawdust. Set aside for 2 weeks.

Features of substrate care:

• the optimum temperature is not higher than +20 ° С;
• sufficient moisture.

Before planting, the soil is covered with a film to warm up. Sprouts 8 cm high are watered with complex mineral fertilizer and planted in prepared holes. First, the potato planting is covered with straw or hay, and then with a film.

Sawdust and plant insulation

So that the sawdust does not get wet, they are stuffed into bags. Then spread around the plants. If sawdust is poured around the plant and not covered, then they will get wet and turn into an ice crust in winter. Rodents also like to hide in them, so be sure to cover them with polyethylene.

Sawdust for seed germination

Seeds are comfortable in moistened sawdust, but if the plant is not transplanted on time, it will die.

The germination technology is as follows:

1. Sawdust is poured into the container and the seeds are laid out.
2. Sprinkle with a thin layer of sawdust.
3. Cover with polyethylene and clean in a warm place (+ 25 ... + 30 ° C).
4. As soon as shoots appear, the container is cleaned in a cool place.
5. Remove the polyethylene and sprinkle with soil.
6. Dive when the first true leaf appears.

This technology can be applied when germinating any kind of seeds.

DIY fertilizer

Nutritious compost can be prepared in 4 months. Dense polyethylene is spread on the ground, shavings, weeds, foliage are poured. Add 200 g of urea and pour 10 liters of water or mullein. Cover with polyethylene on top to create a greenhouse effect. Under the influence of sunlight, the process of reproduction of microorganisms begins, and the sawdust quickly rots. The main thing is to monitor the humidity inside the heap and mix it periodically. Vegetables and raspberries can be mulched with half-ripe sawdust.

A month later, the sawdust that has percolated is ready for use in the beds. The constant use of such a fertilizer will make the soil loose, similar in consistency to the one sold in flower shops.

Cons of using sawdust and cautions

So, we have already found out whether fresh sawdust in the garden brings benefit or harm. If sawdust is introduced without waiting for the moment when it is completely overheated, then the wood will take some of the nitrogen from the soil for the decomposition process, as we discussed above. And also the acidity of the soil may increase, the growth of beets and cabbage will slow down.

Before the onset of winter, it is not recommended to cover the beds with a thick layer of sawdust, since the layer will begin to overheat from below, and no changes will occur from above until the onset of spring. Spruce or pine shavings contain a lot of resin, which garden plants do not like. sawdust generated during construction works may contain chemicals. Therefore, they are used with caution.

Mulching is the surface covering of garden and vegetable garden soil with mulch, which can be crushed bark, pine needles, sawdust and other natural materials. This agricultural technique avoids many health problems of cultivated plants on the ground and in the greenhouse. Using sawdust as a mulch can achieve amazing results in the growth and development of a plant, but only if certain rules are observed.

Properties of wood chips and shavings

Sawdust mulch is suitable for use on all types of soil. What is good about this material:

• Does not release moisture from the ground, thereby helping to maintain the balance of water in the dry season and in hot areas;
• Does not allow weeds to grow. This is one of the main reasons for the use of wood waste as a mulch powder;
• Fresh sawdust is used as bedding for berries - the smell of wood repels some pests from fruits, and clean small chips keep strawberries and strawberries clean;
• Mulching the soil allows the roots of some plants to survive the winter;
• Wood chips serve as fertilizer. True, for this you need to fulfill some conditions.

It is worth noting that mulching with sawdust cannot be done in the form in which they are. The fact is that wood does not saturate the soil with useful substances, but, on the contrary, draws them out like a sponge. Sawdust material becomes useful if it is added to the main mixtures for fertilizer or kept for a year or two in a compost heap. At this time, bacteria settle on the surface of the chips, which saturate the wood with useful microelements released during decay and reproduction of microflora.

What are the benefits and possible harm?

Sawdust is often used by gardeners to improve the quality of plant life, but not always a person knows about the true benefits of taking it and is not able to accurately assess its harm. However, in most cases, a positive effect is still obtained from their use. Sawdust in the garden - good or bad?

Advantages of sawdust:

• With proper preparation, an excellent humus is obtained, similar in properties to traditional manure, which, as you know, costs a lot.
• Sawdust scattered on paths in the garden prevents the spread of weeds.
• Retain moisture in the soil, especially in spring. To do this, it is necessary to mulch the soil in the fall.
• Contribute to the natural aeration of the soil a few years after use.
• Coniferous shavings and chips practically do not tolerate pathogenic microbes, which eliminates the risk of plant infection.

Harm of wood waste:

• sawdust in pure form- not fertilizer. According to some reports, they absorb minerals from the soil and the soil becomes depleted. To be more precise, nitrogen is drawn out from the fertile layer, which is necessary for the vital activity of microorganism.
• Fresh sawdust oxidizes the soil.
• When using sawdust of unknown origin, it is possible to infect plants with certain diseases. To eliminate this drawback, you should not take material from unknown sources.

What sawdust to use

Shavings of different trees are not suitable for all plants:

• Waste of deciduous trees is suitable for all cultures, except for oak.
• Conifers saturate the soil with acid, therefore they are only suitable for lovers of such an environment - tomatoes, cucumbers, carrots and others.

Several fertilizer recipes

Sawdust in its pure form is only suitable for filling paths in order to retain moisture and stop the development of weeds. In other cases, the preparation of raw materials is required.

In order for sawdust in the garden to become useful, they need to rot. To achieve the desired condition, they will have to lie down for at least 10 years in a pile, while the bacteria process the wood into a useful substrate. To speed up the process, you should make compost from sawdust. In combination with manure and additional additives, the fertilizer ripens faster due to thermoregulation in the right range and maintaining a sufficient level of humidity.

Recipe 1: wood and ash

Lay down:

• Wood sawdust - 200 kg;
• Urea rich in nitrogen (up to 47%) - 2.5 kg per pile;
• Ash necessary for alkalization of the soil - 10 kg;
• Water - 50 liters;
• Grass, food waste and drains - up to 100 kg.

Shavings and grass are laid in layers, ash is added and the “pie” is poured with urea dissolved in water. You can cover the pile with polyethylene film, but small pores should remain in the surface: this way the temperature and humidity level will be optimal, and oxygen will remain available.

Recipe 2: Enriched with organics

For poor soil that requires a significant dose of fertilizer, prepare this compost from sawdust:

• Wood waste - 200 kg;
• Cow dung - 50 kg;
• Fresh cut grass - 100 kg;
• Organic waste (food, feces) - 30 kg;
• Humates - 1 drop per 100 liters of water (no more).

When this fertilizer ripens, a significant amount of nitrogen is released.

Fertilizer from fresh sawdust

As already mentioned, fresh sawdust does not benefit the soil as a fertilizer for the garden. If you have not done composting in advance, but it is necessary to saturate the soil, use a sawdust mixture with the following additives per bucket of wood chips:

1. Ammonium nitrate - 40 g;
2. Granular superphosphate - 30 g;
3. Slaked lime - 120 g (glass);
4. Calcium chloride - 10 g.

The mixture must be infused for 2 weeks. To do this, spread polyethylene on the street and sprinkle the ingredients on it.

Mix and leave to isolate the necessary elements and carry out chemical reactions. After that, add the resulting mixture to the soil when digging the beds. The earth will receive a sufficient dose of ammonia, the acid-base balance of the soil will be leveled, the release of useful substances will occur immediately after the first watering. Fertilize the soil should be in the amount of 2-3 buckets per 1 square meter site. This procedure contributes to the natural loosening of the soil.

How to properly mulch

Sawdust in the country is useful not only for speeding up the composting process, but also for sheltering plants in winter, fertilizing them and protecting them from pests.

Prepared sawdust as a mulch is good to use in the first half of summer, when seedlings and plants are just gaining strength and need protection from weeds, soil moisture loss and disease attacks. By the middle of summer, there will be no obvious trace of the powder - it will be mixed with the earth by rains and worms.

Basically, sawdust saturated with fertilizers is lined in the aisles. This must be done between beds with tomatoes, potato rows and other plants.

Other vegetables grown in the garden - onions, carrots, beets, garlic, turnips - also need a protective powder. It must be done after picking, when the plantings are thinned out and have reached a height of 5-7 cm, for them a 3-4 cm layer of sawdust is lined.

Raspberries are one of the main fans of mulching in the garden. It is necessary to preserve the soil moisture necessary for setting berries. Prepared sawdust is plentifully poured under the bushes.

Strawberries and wild strawberries

Is it possible to mulch strawberries with sawdust? The answer is unequivocal - it is possible and necessary, just like strawberries. This procedure is useful for berries:

• Sawdust maintains the balance of moisture in the soil;
• Tender fruits remain clean without touching the ground;
• Slugs and snails do not crawl on the berries.

For mulching, clean sawdust without impurities is needed, but before the procedure it is important to saturate the soil with minerals and fertilize well to prevent the impoverishment of the fertile layer. The material used can be mixed with urea in the above proportions.

Sawdust is moistened and laid out under the bushes, under each branch and between the bushes.. The layer thickness should be 5-7 cm. This work is presented in the video.

Backfilling is done when the seedlings are already rooted and have gained a height of more than 7 cm. Mulching strawberries with sawdust for the winter will help perennial plant it is better to survive the winter and keep the root system intact.

How to cover roses

Gardeners say: “A rose is a child of manure”, because sawdust is necessary for it as a fertilizer, but they are not suitable as a shelter for the winter, such a mulch does not have sufficient heat-retaining performance.

Shelter of roses with sawdust can be used for wintering only in combination with other, more effective materials. The expert will talk about this in more detail in the video.

Sawdust for seedlings

Tomatoes and other seedlings do not come to the garden and garden as seeds, but in the form of ready-made seedlings. They can also be bred in small wood waste - such an environment is more favorable for a tender seed than soil. How to properly organize the process:

1. Moistened small chips are poured into a flat container;
2. Seeds are planted, they are generously sprinkled with fertilizer, since there is nothing nutritious in the sawdust;
3. Cover with a film, make holes for air and expose to the sun;
4. When sprouts appear, soil is poured on top so that the plant gets used to it.

The advantage of germinating seeds in woody material is a loose environment that allows the seedling root system to develop intensively, but only if there is an adequate supply of nutrients.

Various production wastes are often used in the household.

Often they can successfully replace purchased products and turn out to be no worse in quality.

Waste generated in the process of sawing wood (sawdust) can be very helpful in the garden.

After all, with their help:

• fertilize the soil, making it more fertile;
• create favorable conditions for the germination of seedlings and seedlings;
• fight weeds;
• regulate the acidity of the soil;
• protect the roots of plants from drying out and frost;
• make the paths cleaner and more comfortable to move.

Use before planting

Most types of seedlings need to be planted at the very beginning of spring, when the air temperature at night often drops to negative values.

Because of this, the soil temperature does not exceed +5 degrees, so it the roots do not develop well, and the plant is sick.

If it is not possible to put a greenhouse, then good decision it may turn out to be filling fresh wood waste into grooves or holes.

Sawdust needs to be poured 3-5 cm below the level of the roots, so make the seats a little deeper.

Having dug a hole or groove and laid some sawdust on the bottom, water them with any fertilizer that contains nitrogen and phosphorus, you can also put a few grains of urea.

In this case, the bacteria that ensure the decay of wood waste and raise its temperature will take these substances from the fertilizer that has soaked the ground and the top layer of soil will be provided with constant heating, and also will not lose the trace elements necessary for plant growth.

Wood sawing waste is better suited for such bedding. deciduous fruit trees (pear, apple, apricot, etc.). If such sawdust is not available, then any other leafy waste can be used, mixing it with a small amount of manure or droppings to speed up the decomposition of wood.

If only coniferous sawdust is available, then they need mix in equal parts with manure, and also treat with aerobic bifidobacteria. Such drugs are sold in garden stores, they can also be bought on the Internet, for example, here. The cost of packaging sufficient to process 25 m2 is 4–4.5 thousand rubles.

Sprinkle over the sawdust a mixture of garden soil and humus, because in most cases the garden soil is very depleted, so the plant will not be able to develop normally in it.

There are many useful substances and trace elements in the mixture of earth and humus, so the planted seedlings will not suffer from their lack.

Do not mix the earth with unripened sawdust, droppings or manure, because this mixture will burn the roots of plants and you won't get a harvest.

If you have completely rotted sawdust, then they can also be added to the mixture of soil and humus, they will improve the structure of the soil, so that the earth will be better filled with water, air and various nutrients.

In addition, rotted sawdust will provide the plant with additional nutrients, in particular calcium and phosphorus.

This method of planting can be used for any garden plants, however, for the best result take into account the acidity of the soil.

You can determine it using analyzes or by plants on the site. If they grow there:

• sorrel;
• horsetail;
• buttercup;
• acid;
• blueberry,

then earth is very acidic and pits or grooves for planting need spill with a solution of slaked lime, and sprinkle the bottom layer of sawdust with wood ash.

If on the site appeared:

• heather;
• fern;
• cornflowers,

that's enough shed holes or grooves with lime mortar.

Most root crops, as well as cucumbers and tomatoes, love moderately acidic soil, so if there are no plants listed above on the site, then sawdust poured into the bottom of the hole, groove or furrow, slightly acidify the soil, so that the seedlings will grow better.

Overripe sawdust does not change either the acidity or the amount of nitrogen in the soil, therefore, by mixing them with soil and humus, you only contribute additional fertilizers, therefore no adjustment of acidity or amount of nitrogen is required.

The same method of adding sawdust to the bottom of grooves or holes can also be used for planting seeds directly into the ground. However, for such a planting, a greenhouse is needed, because the time for planting the seeds is in February and March, so the debate of sawdust will not be able to warm the earth and air to the desired level.

Planting seeds on sawdust allows you to meet the deadlines and avoid transplanting from pots into the soil that injures the roots of plants, because, unlike the earth, sawdust has a very loose structure, therefore when transplanted, the roots are preserved intact.

If you are going to grow seedlings in separate containers, and then transplant them into open or closed ground, then completely rotted sawdust should be mix with earth and humus. This will provide the maximum amount of nutrients and elements necessary for seedling growth.

Fertilizer

Sawdust is a good material for obtaining fertilizers, and depending on the method, its composition, characteristics and the time during which they turn into fertilizer change.

Here main methods of obtaining fertilizers:

• natural decay;
• rotting with droppings or manure;
• rotting with the addition of bifidobacteria.

The process of natural decay takes several years., and its speed depends on the type of wood, humidity and temperature.

Soft hardwoods rot the fastest. The process lasts somewhat longer in medium-hard hardwood waste. The sawdust of coniferous and hard hardwoods rots the longest.

Adding litter or manure to wood waste accelerates their decay, as well as makes ready-made humus more useful.

In addition to glucose, calcium and phosphorus, it contains nitrogen and other useful substances. Adding bifidobacteria to the mixture of sawdust and litter or manure allows you to get ready-made humus within a few months.

Such fertilizers can apply from autumn to spring. In the summer, when the plants are gaining strength and bearing fruit, this is undesirable. After all, the earth must take in the fertilizer and mix with it, otherwise, in the area of ​​\u200b\u200bthe roots, areas will turn out where the content of nutrients exceeds not only the norm, but also a safe value.

That's how it gets vegetables soaked in nitrates- fertilizer was introduced at the wrong time and it did not have time to dissolve in the ground. As a result, the roots of the plant were not in the ground, but in the fertilizer and absorbed too many nitrogen compounds.

Mulching

After watering, water not only saturates the soil and goes into the depths, but also evaporates from the surface.

The evaporation process directly depends on the wind speed and air temperature, so on sunny or windy days the earth dries up quickly.

As water evaporates, soil moisture drops and plant roots lose their ability to absorb nutrients and trace elements necessary for growth.

The roots can only absorb an aqueous solution of these substances.

A layer of sawdust laid on top of the ground (mulch) reduces the rate of moisture evaporation, due to which plants absorb water solution more efficiently and need less watering.

Fresh sawdust negatively affects the acidity of the soil, and also draws nitrogen out of it, therefore, immediately after laying the mulch from sawdust, the earth must be watered not only with water, but also solution of nitrogen-containing and alkaline fertilizers.

In addition, these fertilizers need to be applied 2 more times throughout the season - in mid-spring and mid-summer. For more information about this process, as well as various combinations of fertilizers, read the article (Sawdust mulch).

Weed and pest control

Chemical control methods used in the fields, not always applicable in the garden, because domestic animals often run along it, which can be poisoned. Therefore, gardeners are forced to look for other ways to fight, one of which is backfilling the earth with a thick (5-10 cm) layer of sawdust.

This is similar to mulching, however, not only the space around the stem of the plant is covered, but the entire garden.

Wood waste, laid in a thick layer, deprive seedlings of weeds of sunlight, because of which they cannot grow and soon die off.

Slugs are one of the most dangerous and tenacious pests living in vegetable gardens. Mulch from fresh sawdust sticks to the body of the slugs, because of which they lose the ability to crawl and soon dying from dehydration.

This mulch should be sprinkled once a week with a thin layer, as well as pour coffee residues dissolved in water which is detrimental to slugs.

If you only have rotted sawdust, then due to the softening of the wood during the process of decay, they can no longer stop slugs, therefore useless in the fight against these pests.

Backfilling tracks

During the rain the paths between the beds become limp and turn into an impenetrable mess, so many gardeners fill them with various materials.

Wood waste is better suited for this task than crushed stone, broken slate or brick, because they not only eliminate dirt, but also improve soil structure. In addition, the lower layer of backfill gradually rots and after 1-4 years, depending on the humidity and type of wood, it turns into a good fertilizer, which is received by nearby plants.

If, over time, you decide to change the shape or location of the beds / plantings and dig up the garden, then in this case, sawdust will be useful.

They will improve the structure of the soil, making it looser, and also fill the soil with nutrients.

To reduce the negative impact of wood on the soil, 3-4 times a year, spill the paths covered with sawdust with urea and slaked lime or ash solution.

These preparations compensate for the loss of nitrogen in the soil, and also adjust the acidity of the soil to an acceptable level.

Choosing between coniferous, including pine and hardwood sawdust, consider different time their decay. Hardwoods turn into humus much faster, and the softer the wood, the less time is needed for this process.

Waste sawing alder or poplar will rot in 1-2 seasons, and oak or coniferous - in 3-5 seasons.

Can do not divide the garden into beds and paths, filling the entire area with sawdust. The optimal layer thickness is 10 cm. In this case, it is advisable to use rotted sawdust, because before winter and spring it is advisable to dig up the earth.

Fresh wood, once in the soil, will acidify it and reduce the level of nitrogen. If there is no decaying wood waste, then immediately after backfilling and in the fall, after harvesting, pour sawdust with a solution of litter or manure, as well as a means that accelerates the reproduction of bifidobacteria.

From spring to autumn, these sawdust will play the role of mulch and dumping, and bacteria will turn them into high-quality fertilizer by spring. By plowing the entire garden, you will mix the soil with fertilizer, so that all plants will receive a more abundant and balanced nutrition.

Coniferous and deciduous - which is better for the garden?

On numerous forums, users often ask the question - what kind of sawdust is best for the garden and is it possible to use coniferous or some other wood waste?

When applied correctly any sawdust brings many benefits, but improper use can be harmful and completely destroy the crop making the land unsuitable for growing some plants.

Any wood sawing waste make the soil more acidic and also draw nitrogen out of it, therefore, it is necessary to apply fertilizers along with them to compensate for these changes.

Sawdust, both completely or partially rotted, and fresh, improve soil structure, which is especially important on clay soils. On particularly heavy soils consisting of solid clay, it is necessary add sand along with sawdust.

Fresh wood waste in the process of decay is very hot, which leads to an increase in soil temperature and overheating of plant roots, so fresh sawdust can not be laid close to the roots.

So there is not much difference between coniferous and deciduous sawdust - when used correctly, they bring many benefits, and mistakes can be harmful and lead to sad consequences. Most of the negative reviews about the use of sawdust in the garden are due to their incorrect use, while those who used them correctly are satisfied with the results.

Conifers

However, it is important to understand the differences between hardwood and softwood sawdust and how the latter affect the soil.

In most cases, coniferous sawdust means pine or spruce sawdust as the most accessible, as well as as cheap as possible. Pine and spruce are used for most joinery and carpentry, so sawdust is everywhere.

Fresh pine and spruce sawdust due to the high resin content, they rot much longer deciduous, and also draw more nitrogen from the soil.

Improper use of pine and any coniferous sawdust causes much more damage to the garden than hardwood.

Due to the high content of resins, humus from sawdust contains more microelements necessary for plants, therefore it is better suited for a balanced top dressing.

If coniferous sawdust is laid in furrows, ditches or pits, then due to the greater need for nitrogen for complete decay, it is necessary to increase the amount of nitrogen-containing fertilizers.

In addition, pine sawdust more acidic soil, so you need to increase the amount of slaked lime or ash.

Use pine and other coniferous sawdust in the garden not only possible but necessary, taking into account their features and compensating for the negative impact on the land. Only in this case they will bring a lot of benefits.

Deciduous

Due to the lower resin content, humus from leafy waste is a little less balanced, but they rot faster. In addition, hardwood sawdust is less accessible, so dried and chopped branches and twigs of fruit trees are often used in the garden.

Using such material, be careful, because among the dried branches often come across sick or injured various pests.

Such sawdust cannot be used, because bacteria will not be able to process pests and pathogens, therefore fertilizer from them can infect your plantings.

Summarize

sawdust is very useful stuff useful for any gardener. After all, they are used for:

• mulching;
• dumping tracks;
• plant nutrition;
• improve soil structure;
• earlier planting of seedlings or seeds.

After reading the article, you learned how to use this material correctly and what mistakes gardeners most often make.

Inexpensive and affordable natural material - sawdust. They can be purchased at the nearest sawmill, obtained at own site during construction, sawing firewood. Farmers have found many ways to benefit from this waste. However, do not forget that they can be harmful. Further in the article, let's take a closer look at such aspects as the benefits and harms of using sawdust in the garden. And also how you can fertilize or treat the beds with them.

Varieties of small wood waste

Small waste from sawing wood is divided into chips, large and small fractions. There are also differences in the type of wood: from coniferous or hardwood. Sometimes differences are important, for example: leaf waste rots faster; conifers are not suitable for smoking products, etc. But any organic matter is valuable. Before use, it is desirable to process sawdust.

Benefit and harm

1. For humans and the environment, the presence of impurities such as creolin, chemical oils, paint particles, glue, gasoline is dangerous. That is why it is necessary to take processed wood products, and not chipboard or sleepers.
2. Resinous substances inhibit the germination of seeds, the development of plants. This disadvantage is neutralized by scalding the substrate with boiling water, as well as by composting.
3. Underripe organic matter (when applied to the soil and on its surface) begins to decompose by microorganisms that intensively consume soil nitrogen. Because of this, plants experience nitrogen starvation - turn pale, develop worse. Therefore, it is recommended to put only rotten sawdust into the ground, and when mulching fresh, flavor them with nitrogen fertilizers.
4. Sawdust compost acidifies the soil. Simultaneous alkalization is necessary (in autumn - with lime, in spring - dolomite flour, ash).
5. Seedling sawdust soils dry out too quickly. It is necessary to observe the recommended proportions of the components, monitor the regularity of watering.

Mulching

Sawdust mulch is a cheap and convenient option. They cover it in the country:

• surface of ridges with vegetables and strawberries
• soil in raspberries, flower beds
• tree trunks in the fruit and berry garden

Sawdust in bags ready for soil mulching

The thickness of the layer can be from 4 to 20 cm.

Mulch is placed in spring or early summer, and for fruit and berry and ornamental crops it can also be done in autumn. At the beginning of the season, rotten sawdust compost of the last or the year before is used; at the end of the season, spring composting organic matter is suitable.

It is permissible to mulch with fresh sawdust. They are pre-cooked: soak strong mortar nitrogen fertilizers. To do this, 3 buckets of mulching material are poured with 10 liters of water, where a quarter kilogram of carbamide or nitrate is dissolved. It is best if this mixture stands for a couple of weeks before mulching (covered with polyethylene), after which you can pour it on the beds. Mineral fertilizers can be replaced with fresh manure or manure (2 liters), but this mulch is not suitable for strawberries and some vegetables (for hygienic reasons).

Advantages of sawdust mulch

1. the material is not clogged with weed seeds
2. gradually overheating, the mulch enriches the soil with organic matter
3. moisture is saved
4. no soil crust and erosion
5. roots are warmed, temperature differences are smoothed out
6. comfortable for beneficial soil inhabitants (microorganisms, earthworms)
7. the exit of some pests is difficult
8. no dirty splashes from rain and watering - cleaner food and less disease
9. inhibits the growth of weeds
10. ridges, garden, flower beds look well-groomed and beautiful

How to fertilize with compost

The best way to dispose of sawdust is proper composting. Just poured out in a large heap, they will rot for several years (especially from coniferous trees). Rotting is accelerated by layer-by-layer mixing with substances such as

• manure, litter
• feces
• foliage
• herbal humus
• dolomite flour, ash.

The mass is regularly shoveled and spilled with water, as well as solutions of mineral fertilizers, herbal infusions, biological preparations (Baikal, Flumb Super, Radiance). The process of compost maturation usually lasts from six months to two or three years. The minimum waiting period is 2 months.

Mixed compost is considered the best organo-mineral fertilizer for all crops.

Compost made from sawdust

Bookmarking in the soil and greenhouses

Fertilizer "works" in the ground for 3-5 years: it nourishes plants, loosens heavy loams.

Small wood waste is also used when laying biofuel in greenhouses and greenhouses. They are mixed: fresh sawdust to fresh manure, rotten to rotted (in a ratio of 1: 1).

Use of sawdust in greenhouses

Neutralizer of harmful substances

A fresh mass of small wood waste serves as an "ambulance" in case of emergency. It is added to the ground if an excess of nitrogen and other fertilizers is noticed. So plants will avoid fattening, accumulation of nitrates and harmful salts.

Acidifier in the beds in the garden

Sawdust is useful when planting and mulching those plants that love hyperacidity soil (hydrangeas, rhododendrons, azaleas, heathers, blueberries).

Pine sawdust as a desiccant

sawdust compost

Fresh sawdust can absorb an amount of liquid that is 5 times its volume. They are good for filling drainage ditches, paths between high ridges in wetlands.

temperature insulator

In regions where temperatures are low in winter, dry sawdust covers the root zone and branches of shrubs (grapes, hydrangea, rose, clematis) from freezing, planting winter garlic and perennial flowers (lilies, irises, chrysanthemums). To avoid warming up, the shelter is made at the onset of sub-zero temperatures, and the opening is done early in the spring. To protect against dampness, a waterproof material (polyethylene, roofing material, etc.) is placed on top.

Some fruit and berry crops bloom very early, and the ovaries freeze slightly. If the root zone is covered with a powerful sawdust layer, then the trees and shrubs will wake up later. Flowering will move to a more comfortable time.

Rose bushes sprinkled with sawdust for the winter

Pest repeller in the garden

Small wood waste is impregnated with tar or gasoline, laid out to repel rodents, onion and carrot flies.

Adding prickly sawdust makes it difficult for snails and slugs to move. The resinous aroma partially protects plants from the attack of beetles (Colorado, raspberry, flower beetle, weevil).

Additive to seedling soil

A soil substrate containing 10 to 50% rotten sawdust compost is recommended for

• vegetable and flower seedlings
• rooting cuttings and strawberry whiskers
• growing seedlings with a closed root system.

Other components of such soil are garden soil, peat, some sand. Loose soil requires frequent watering or special moisture-retaining additives (hydrogel, vermiculite, coconut substrate).

Underripe organic matter can cause starvation of young plants. If the foliage has turned pale, then it is necessary to give nitrogen-phosphorus top dressing.

Walkway covered with sawdust

Use of the substrate as a fertilizer

In fresh small sawdust, seeds of cucumbers (as well as zucchini, pumpkins, melons and watermelons) are germinated, seedlings are kept. The substrate is poured with boiling water, then the water is immediately drained. The procedure is repeated twice to wash off the resinous substances. The warm wet mass is laid out in a layer of 6 cm, dry seeds are placed in it to a depth of 1.5 cm (with a distance of 3 cm from each other). Crops are covered with a film and placed in a warm place. Shoots "shoot" after 3-4 days. Seedlings are ready for planting in two weeks.

In sawdust, you can make the forcing of green onions, tulip flowers. The substrate must first be shed with boiling water, flavored complex fertilizer dominated by nitrogen. Potato and dahlia tubers are germinated in the same way before planting.

The middle fraction of crushed wood of deciduous trees is used in the artificial cultivation of mushrooms such as oyster mushrooms.

Medium for winter storage of rhizomes and tubers

In autumn, flower growers dig up dahlia tubers, callas and begonias, canna rhizomes. They are stored in a cellar or refrigerator, sprinkled with dry, fresh sawdust. Resinous components inhibit decay.

This method is not suitable for preserving lilies and onion sets (they will lose turgor).

Farmers are diligent and creative people. They are able to convert waste into income, especially when it comes to organics. As you can see, the use of pine or any other sawdust can be beneficial in the right hands.

Sawdust as a mulch and a heater for fruit trees, berries, flowers is used by many gardeners. But wood waste has other useful properties. This is an excellent basis for making nutritious compost. In what cases can sawdust be used as fertilizer, how to apply them? Let's talk about this in more detail.

Sawdust - affordable fertilizer

The soil for growing crops in different regions of Russia is very different. And in many areas, the use of sawdust is a necessary measure to improve the structure of the soil in summer cottages and gardens. It just needs to be done right.

Of course, crushed oak or other waste cannot be considered a full-fledged organic fertilizer. Sawdust improves the mechanical properties of the soil, it becomes airy and loose, perfectly absorbing moisture. But in order to understand how small particles of wood affect the nutrient layer of the soil, you need to know the composition and properties of wood chips.

The composition of sawdust includes many useful trace elements, fiber, resins, essential oils and other microelements necessary for the plant. But this composition is only for the correct compost sawdust.

sawdust properties

Sawdust are the smallest pieces of wood. This is waste from the woodworking industry. Often there are sawdust in summer cottages where construction is underway. By value, wood waste is superior to peat and manure, they contain more valuable substances. It is a cheap and readily available material.

In its pure form, wood cannot be a fertilizer. It contains a lot of nitrogen, lignin, cellulose, resins, they bind many useful substances, impoverishing the soil. This is due to the fact that during the decomposition of sawdust, a lot of fungi, bacteria, microbes are formed, which take useful elements(phosphorus and nitrogen) in plants. The soil starts to oxidize.

It is not recommended to add sawdust to the soil fresh, but it is possible to spread it on top, but in a small layer. Most often, the soil around trees and shrubs is mulched to retain moisture and heat. If you use sawdust as fertilizer or mulch on strawberry plantings, wood waste will help protect the berries from pests and rot.

Mulching with sawdust is carried out only until mid-summer. By the end of August, the sawdust will completely dissolve due to the constant loosening and activity of the worms. If a thick layer of sawdust is poured during the rainy season, excess moisture will not evaporate from the soil. This will adversely affect the ripening of shoots in fruit trees and berry bushes. Later, it will be difficult for plants to prepare for winter.

How to get fertilizer from sawdust

In order for wood waste to become fertilizer from sawdust, you need to wait a long time, moisture must accumulate in them, microorganisms must appear. The process of obtaining compost from sawdust can naturally last from 5 to 10 years. Heaps of waste will be moistened by rain, that part of them that gets wet will turn black. But it's too much long process. You can speed it up by mixing sawdust with mineral fertilizers, fertile soil, regularly pouring water from a hose.

sawdust compost

It is necessary to take waste only from the purest wood. When the trunks are treated with impregnations, they can only fill the soil with toxic substances. Almost all plants can be composted into a mixture with sawdust. Exceptions are perennial weeds, wood and bark of old trees. Small waste is easily composted, quickly acquiring the desired useful properties.

Speeding Up the Process with Amplifiers

Stages of obtaining compost

Conventionally, the process of obtaining fertilizer from sawdust can be divided into three stages:

1. Decomposition. The mixture actively releases heat, which contributes to a change in the structure of the conglomerate components. Beneficial microorganisms are born in the mixture: lactic acid, photosynthetic, yeast bacteria, fermenting fungi, actinomycetes. Entire colonies of earthworms are formed, they speed up the process of processing sawdust into fertilizer.
2. Humus and its formation. At this stage, you need a lot of oxygen, it is necessary for the active reproduction of microorganisms. Heaps need to be mixed manually with a pitchfork or a shovel.
3. Mineralization. Organic residues decompose. A large amount of carbon dioxide is released.

How to make sawdust compost in 14 days

You can prepare healthy organics in two ways:

• slow (cold);
• fast (hot).

With the cold method, a more useful and high-quality substrate is obtained. But it takes too long to get it. If you want to get compost quickly, you need to fulfill three main conditions:

• Heat loss must be prevented. This can be done by putting the mixture in a container. With the hot method, only a limited amount of fertilizer can be prepared.
• It is necessary to provide natural aeration. To do this, make holes, slots in the walls of the container for air access.
• Grind all ingredients. The size of the fractions should be no more than 15 cm.

How is compost mass formed?

In order for the compost formation to proceed quickly, the following conditions must be observed:

• the mixture had to be under the sun;
• the container should not be blown by the wind;
• components are divided into two separate fractions: dry and solid (branches, shavings) and green (weeds, foliage, tops);
• in the compost heap, all components are stacked in layers;
• at the bottom there should be a layer of dry grass and leaves, then there should be a layer of sawdust mixed with a dry fraction moistened with liquid mullein or urea. The next layer is a wet fraction with manure, forest soil, chopped hay, then again there should be an alternation of layers, where the first layer will be sawdust.

The optimal height of the container with the substrate is about a meter. The area is not less than a square meter. The container should be closed with a dense material. If everything is done correctly, after three days heat will begin to be released. Regularly the mixture must be shoveled, providing air access.

You need to make sure that there are no smells from the compost pit. If there is a smell of ammonia, there is an excess of nitrogen in the compost, it is worth adding a small amount of shredded paper. If there is a smell of hydrocarbon, the reservoirs are lacking oxygen.

Sawdust as a fertilizer, how to apply

Sawdust nutrient substrate absorbs chemical and toxic substances from the soil. Due to this, heavy metals and nitrates do not accumulate in fruits and berries.

Fresh sawdust is also used in saline soils. They allow them to improve their health without negative consequences. Experienced gardeners recommend adding sawdust compost to poor soils 3-4 years in a row. If the land is fertile - a year or two. The result of sawdust fertilizer lasts for five years, in terms of efficiency it is comparable to cow dung.

The use of sawdust in greenhouses

In greenhouses, it is effective to use sawdust as a fertilizer, as well as any compost based on them. Before planting seedlings in the spring, a layer of fresh sawdust up to 25 cm thick is scattered in the greenhouse. Mineral fertilizers are scattered from above. Per square meter take:

• wood ash - 300 grams;
• double superphosphate - 200 grams;
• ammonium nitrate - 250 grams;
• potassium sulfate - 120 grams.

If not mineral, but organic fertilizers are used, the usual dose is increased. For chicken manure - 2 times, for a solution of ordinary manure - three times. Sawdust is poured with water at room temperature, mixed after the spill. The procedure is carried out a month before the date of planting seedlings.

When growing cucumbers in a greenhouse, sawdust top dressing is used, but it is necessary to fertilize the plants with nitrogen fertilizers every week before harvesting the fruits. During the fruiting period, complex fertilizers are used. Every year a new portion of sawdust is added to the ground.

On fresh sawdust, you can grow seedlings of cucumbers, squash, zucchini, as well as pumpkins, melons, watermelons, onions. Almost any seedling of vegetables can be grown on a sawdust basis.

Sawdust for growing potatoes

Almost rotted sawdust is used to grow early potatoes. A layer of birch sawdust or any other is poured into the prepared boxes, germinated tubers are placed on it. A layer of sawdust is again poured on top. The boxes should be at a temperature of 20 degrees, keeping the substrate moist. With an increase in sprouts, sawdust is watered with a solution of urea. Potatoes, along with sawdust, are planted in holes, covered with earth. Landing is covered with hay or straw.

Many gardeners use sawdust as a heater and mulch for berries, fruit trees, flowers and other heat-loving plants. They do not even realize that sawdust has other useful properties. This is a good basis for the preparation of nutritious organic matter - compost.

In Russia, the territory is huge, and the land for cultivating crops varies greatly from region to region. In many places, the use of sawdust to improve the structure of the soil in vegetable gardens and summer cottages in order to increase yields is an objective necessity. It just needs to be done correctly and consciously.

This type of crushed wood waste can not be considered a full-fledged organic fertilizer in any condition. Although, first of all, they improve the mechanical properties of the soil. The fertile layer becomes more loose, airy, perfectly absorbs moisture. But in order to understand the influence of the smallest particles of a tree on other components of the nutrient layer of the soil, it is necessary to know their properties.

The composition of the rotted sawmill waste includes fiber, many useful trace elements, essential oils, resins and other necessary plant substances. Decomposed particles from sawing logs saturate the soil with carbon, which serves as a breeding ground for beneficial microorganisms. But only the right compost sawdust has such properties.

Since sawdust is the smallest particles of wood or otherwise crushed waste from sawing wood on sawmills, circular saws, gasoline and hand saws, their stocks are created where woodworking shops, carpenters work, and buildings made of wood are built. A lot of them are also formed in summer cottages, if construction is underway there. Wood shredded waste by value and set nutrients inferior to manure and peat, but the benefits from them can be obtained more due to their availability everywhere. You just need to know how to use them properly.

Wood in its pure form cannot be fertilizer. It contains a lot of nitrogen (1-2%), cellulose, lignin, resins that impoverish the soil, because they bind many useful substances that plants need. This situation is caused by the fact that during decomposition in wooden grains, countless colonies of microbes, bacteria, fungi are formed, which take useful elements from cultivated plants for their nutrition. These are primarily nitrogen and phosphorus. At the same time, the earth begins to oxidize. Therefore, fresh sawdust cannot be introduced into the ground. They will only exhaust her, and cultivated plants weaken and die. But on top of the earth - you can, but in a small layer. Therefore, sawn waste mulches the area near the trunks of fruit trees in gardens, insulates the soil in berry fields in order to preserve heat and moisture in the soil. A mulch of clean, shredded wood waste under the strawberry bushes will protect the berries from rotting and pests.

With sawdust, the fertile layer becomes more loose, airy, perfectly absorbs moisture

True, it is wiser to use this mulching material only until mid-July, when moisture from the soil evaporates intensively. In this case, by the end of August, only memories will remain from mulching fresh grains of wood, since due to the vigorous activity of worms and frequent loosening, the crumbs from sawing logs will be well mixed with the ground. If you pour sawdust mulch in a thick layer in July, when it rains every ten days, then this layer will prevent the evaporation of excess moisture from the ground. This fact will negatively affect the ripening of annual shoots in berry bushes and fruit trees. It will also make them more difficult to prepare for winter.

In order for the particles of a log to become a substance useful for plants, one must wait a long time until moisture accumulates in them and microorganisms multiply, which will saturate the smallest particles of wood with the elements necessary for plants. And rain jets into the pile of waste from small particles from lumber practically do not pass. Therefore, the crushed wood particles decompose only in the upper layer and at the same time change their color. They start to turn black. This process spreads in depth and after 5-10 years a good humus is obtained from a pile of small particles of wood, having different shades Brown. There is a fundamental difference between manure and sawdust in the process of humus formation. The manure pereprevaet from the inside, and the waste from the sawmill from the outside. Therefore, many gardeners do absolutely wrong, storing small wooden grains in a heap on their plots. They will wait a very long time for humus.

Moisture and living microflora are two necessary components that will turn harmful fresh sawdust into valuable organic fertilizer.

Understanding the conditions for the transformation of pure wood into useful organics, this process can be greatly accelerated. Beneficial bacteria can be introduced by mixing wooden grains with fertile soil, mineral and organic fertilizers, and the necessary moisture will be provided by abundant watering of the mixture with water from a hose.

sawdust compost

There are many recommendations for the preparation of nutrient organics from fresh waste of sawn mass of logs, as the basis of a nutrient mixture, with the addition of various components. Important note: waste should be taken only from environmentally friendly wood. If the sawn trunks were stored in piles before processing, and were treated with various impregnations, then their crumbled waste, apart from harm from toxic chemicals, will not give anything. Almost all vegetable, berry, shrub and non-cultivated plants can be composted in a mixture with sawdust. The exceptions are perennial weed roots, bark and wood, which will take years to complete. The smallest wooden grains are composted easily, quickly enough, with the acquisition of the necessary useful properties. As a result of decay, the crumbled wood particles gradually get rid of the harmful properties inherent in the fresh state: slow mineralization and the ability to oxidize the earth.

The process of obtaining organic fertilizer from sawdust with the addition of microflora can be divided into three periods:

1. Decomposition. During this period, the compost mixture actively begins to release heat, which contributes to a gradual change in the structure of the conglomerate components and enrichment with healthy elements. The result of the transformations is this - in a hodgepodge appear different types useful microorganisms: photosynthetic, lactic and yeast bacteria, actinomycetes and fermenting fungi. Colonies of earthworms are formed, which significantly accelerate the process of processing organic residues into a nutrient substrate.
2. Humus formation. During this period, the most important factor is the presence of a large amount of oxygen required by microorganisms for active reproduction. This is achieved by mixing the heap manually, using a shovel or a pitchfork.
3. Mineralization. During this period, there is a complete decomposition of organic residues and the humus elements themselves to oxides and salts. It is characterized by a large release of carbon dioxide and ends with the release and transition to the available forms of mineral plant nutrition.

Compost mixing

Sawdust compost for 2 weeks

Useful organics are prepared in two ways: cold or slow; hot or fast. The most high-quality, useful, valuable substrate for the nutrition of vegetables and berry bushes is obtained with a cold method. But it takes a lot of time. If you want to make compost from sawdust quickly, three main conditions must be met:

1. Prevent heat loss during self-heating. This can be done by placing the mixture in some container: an iron or plastic barrel, a wooden box, a dense opaque plastic bag. With the hot method of obtaining compost, its volume is limited to several hundred kilograms.
2. Provide good natural aeration. In the walls, sides of any container there should be slots, holes, holes for natural ventilation.
3. All organic material must be crushed with an ax, knife, or chaff before being put into the container. The size of chopped fractions should be no more than 10–15 cm.

But there are a few more prerequisites for the formation of organic matter to feed vegetables to go quickly:

• it is desirable that the compost mixture is under the sun's rays;
• the container must be protected from wind blowing (to avoid heat loss);
• all organic components must be divided into two fractions: wet and green (leaves, chopped tops and weeds, waste from vegetables and fruits, etc.) and coarse and dry - wood chips, waste from working with lumber (chips, branches, etc.) ;
• the compost heap in the container should be laid out in layers of 10-15 cm:
• the lower drainage layer of leaves, chopped dry grass;
• the second layer is sawdust mixed with a coarse and dry fraction, moistened with a solution of urea or liquid mullein;
• third layer - mixed wet and green fraction with manure;
• the fourth layer is soil from a garden or forest;
• fifth layer chopped straw or hay;
• then the alternation of layers should begin again, starting with woody crumbled waste.

Dry fractions are wetted with water. The optimal height of the container for the rapid production of nutritious organics from sawdust is about 1 meter. The base area must be at least 1 sq. meters. From above, the container is closed with a dense light-tight material. If the heap is formed correctly, warming up will begin in 3-4 days. This should be facilitated by the influx of oxygen through the cracks and the desired moisture content of the layers. Every three days, the pile needs to be shoveled, and after two weeks, a rotted conglomerate of wood chips should be obtained, which can be used to mulch beds with vegetables. Important note: shoveling must be thorough so that the mixture is mixed evenly. The nutrient mixture will periodically warm up, and then cool down - this is normal.

There should be no odors from the container with nutrient organics. If they appear, then something in the process of overheating is going wrong.

When the smell of ammonia begins to appear, there is an excess of nitrogen components in the heap (adding a small amount shredded paper will fix the situation). If there is a smell of rotten eggs, the layers are compacted, they lack oxygen (it is necessary to loosen the compost mass).

Nutrient organics from sawdust help the soil absorb harmful chemicals (herbicides, pesticides, excess fertilizer and other chemicals). This prevents the accumulation of nitrates in vegetables, berries and fruits, heavy metals, corned beef and other harmful to human body substances.

Fresh crumbs from sawing wood products are used in saline soils for their improvement. This type of wood waste is also quite effective in combating the negative consequences of applying excessive doses of mineral fertilizers.

Fresh crumbs from sawing wood products are used in saline soils for their improvement.

Experts advise poor lands to be fed with sawdust compost for 3-4 years in a row, and fertile lands - for 1-2 years. The effectiveness of sawdust earth fertilizer is maintained for 4-5 years and is comparable in this indicator with cow manure.

in greenhouses

For greenhouses, both fresh small grains from sawing trunks and any composts based on them are suitable. In the spring, a week before planting seedlings, a layer of fresh, crushed tree particles up to 25 cm thick is scattered around the greenhouse. Then mineral fertilizers are evenly scattered on top at the rate of 1 sq. meter:

• birch or other wood ash - 300 grams;
• ammonium nitrate - 250 grams;
• double superphosphate - 200 grams;
• potassium sulfate - 120 grams.

A layer of waste from the activities of the sawmill and mineral fertilizers is well spilled with water at room temperature (20–25 degrees). If organic fertilizers are used, then their usual dose is increased. For slurry three times, for mortar chicken manure- twice. After spilling the sawdust, they are mixed. This work must be done at least a month before planting seedlings.

Greenhouse cucumbers grown on crushed wood particles every week from seedling growth to harvest finished products, it is necessary to feed with nitrogen fertilizers, and during the fruiting period - with complex fertilizer. In greenhouses, every year you need to add a new portion of fresh sawdust to the ground (if there are no pathogens in the soil).

Onion, seedlings of cucumbers, zucchini, squash, pumpkins, watermelons and melons are grown on fresh, disinfected with boiling water, crushed wood waste. Seedlings of other vegetables are grown on a nutrient basis from sawdust.

sawdust in the garden

Experienced potato growers use semi-ripe sawdust to grow early potatoes. To do this, a layer of particles of crushed lumber about 10 cm high is lined in boxes prepared in advance. Then germinated tubers are laid out on it. From above, they are covered with sawdust with a layer of about 3 cm. The substrate is maintained in a moderately moist state at a room temperature of about 20 degrees. When the length of the sprouts increases to 6-8 cm, the wood chips, along with the potatoes, are watered with a solution of urea. Tubers, along with sawdust, are planted in holes and covered with earth. It’s a good idea to take care of heating the earth in advance by covering it with black plastic wrap. Planted potatoes are covered with straw, hay or non-woven material from a possible drop in night temperatures. Early planted potatoes with good care will give an early harvest of young potatoes.

If it is necessary to make the earth loose, use sawdust for the garden, the benefits and harms of which have been studied by experienced gardeners. But it is not recommended to use fresh sawdust. First they need to be prepared. To do this, add urea or mullein infusion, cover with polyethylene, and then mix from time to time to speed up the process of overheating.

After a couple of weeks, the shavings are ready to be used as fertilizer. Much has been written in the reviews about the benefits or dangers of sawdust in the garden. Experienced summer residents claim that they take nitrogen from the soil, and therefore from plants. They say that you should not use fresh sawdust in the garden, as the plantings will begin to wither.

The benefits of sawdust in the garden

Plants need loose soil to thrive. The addition of rotted sawdust makes the earth a favorable environment for planting garden plants, the roots of which receive a sufficient amount of moisture and oxygen. The use of sawdust allows you to get rid of the crust in the dry season.

They contain a large amount of fiber, essential oils and active substances. The material is successfully used to eliminate soil moisture. To do this, ditches are dug in the aisle and sawdust mixed with lime is poured. Their regular use improves the composition of the soil, reduces the number of weeds, and increases productivity.

What is their secret and how do they work?

They form a natural ecosystem for plants in the garden. It is important to use sawdust that has not been chemically treated or contaminated. Otherwise, they will become a real poison for horticultural crops. If rotted sawdust is used as mulch at the beginning of summer, then by the end of the season, as a result of loosening and the activity of earthworms, they will mix with the soil.

A thick layer of sawdust spread over the surface of the earth during the rainy season prevents moisture from evaporating from the soil surface. This negatively affects the state of fruit and berry crops.

Basic rules for the use of sawdust

Wood shavings are great for mulching the soil. They are sprinkled with a thick layer after planting seedlings.

Advantages:

• the weed disappears;
• soil moisture is maintained;
• insect protection;
• the soil remains loose;
• favorable conditions for the growth of bacteria.

Mulching

Do you need sawdust for the garden in the fall? Everyone is trying to figure out their benefits and harms. As a rule, the soil is mulched for the winter. To do this, fresh sawdust is mixed with peat or manure and scattered on the beds. During the winter, the wood decomposes and becomes a nutritious substance. In the spring they dig or loosen the soil.

High warm beds

The benefits and harms of sawdust for the garden should be studied by every summer resident. How to make multilayer high beds in the bottom of the plot? For such purposes, it is convenient to use sawdust. The top layer of fertile soil is removed. They build a side, cover it with a film to preserve moisture in the garden. A trench is formed and filled with straw, hay or grass. Further, sawdust soaked in urea is placed on top of this, then a layer of organic residues is placed and everything is completed with a fertile layer of earth.

Mulch for strawberries

Do coniferous sawdust in the garden bring benefit or harm? Sawdust, used as mulch under strawberry bushes, protects them from contact with the soil. Thanks to them, the berries are protected from the effects of gray rot. For this purpose, fresh coniferous shavings treated with urea are used. Mulch is applied in the fall to protect the strawberries from freezing and create a barrier to many weeds. Weevil is repelled by pine sawdust in the garden, the benefits or harms of which are learned by practical experience.

Sawdust in a greenhouse and greenhouse

Sawdust is a useful fertilizer for soil in a greenhouse. They are sprinkled with plant residues and manure, which warm up in the spring and quickly overheat. The air permeability of the soil increases, it becomes loose and nutritious. In autumn, straw, mowed grass and tops are laid out on the garden bed.

In the spring, fresh manure is added and sprinkled with lime and sawdust, mixed with a pitchfork. Then lay the soil mixed with ash and mineral fertilizers. To increase the speed of heating, pour boiling water.

Sawdust for early potato harvest

So, why do we need sawdust for the garden? What are their benefits and harms? The use of sawdust helps speed up the potato harvest. Choose tubers of early varieties and germinate in the light. At the bottom of the boxes, 10 cm of sawdust is poured, tubers with sprouts are laid out and sprinkled with moistened sawdust. Set aside for 2 weeks.

Features of substrate care:

• the optimum temperature is not higher than +20 ° С;
• sufficient moisture.

Before planting, the soil is covered with a film to warm up. Sprouts 8 cm high are watered with complex mineral fertilizer and planted in prepared holes. First, the potato planting is covered with straw or hay, and then with a film.

Sawdust and plant insulation

So that the sawdust does not get wet, they are stuffed into bags. Then spread around the plants. If sawdust is poured around the plant and not covered, then they will get wet and turn into an ice crust in winter. Rodents also like to hide in them, so be sure to cover them with polyethylene.

Sawdust for seed germination

Seeds are comfortable in moistened sawdust, but if the plant is not transplanted on time, it will die.

The germination technology is as follows:

1. Sawdust is poured into the container and the seeds are laid out.
2. Sprinkle with a thin layer of sawdust.
3. Cover with polyethylene and clean in a warm place (+25 ... + 30 ° C).
4. As soon as shoots appear, the container is cleaned in a cool place.
5. Remove the polyethylene and sprinkle with soil.
6. Dive when the first true leaf appears.

This technology can be applied when germinating any kind of seeds.

DIY fertilizer

Nutritious compost can be prepared in 4 months. Dense polyethylene is spread on the ground, shavings, weeds, foliage are poured. Add 200 g of urea and pour 10 liters of water or mullein. Cover with polyethylene on top to create a greenhouse effect. Under the influence of sunlight, the process of reproduction of microorganisms begins, and the sawdust quickly rots. The main thing is to monitor the humidity inside the heap and mix it periodically. Vegetables and raspberries can be mulched with half-ripe sawdust.

A month later, the sawdust that has percolated is ready for use in the beds. The constant use of such a fertilizer will make the soil loose, similar in consistency to the one sold in flower shops.

Cons of using sawdust and cautions

So, we have already found out whether fresh sawdust in the garden brings benefit or harm. If sawdust is introduced without waiting for the moment when it is completely overheated, then the wood will take some of the nitrogen from the soil for the decomposition process, as we discussed above. And also the acidity of the soil may increase, the growth of beets and cabbage will slow down.

Before the onset of winter, it is not recommended to cover the beds with a thick layer of sawdust, since the layer will begin to overheat from below, and no changes will occur from above until the onset of spring. Spruce or pine shavings contain a lot of resin, which garden plants do not like. Sawdust generated during construction work may contain chemicals. Therefore, they are used with caution.
