Wood sawdust as fertilizer: how to properly mulch the soil. What can be made from sawdust: we extract benefits and benefits from wood waste Is it possible to use chips

At correct application wood sawing waste (sawdust) increase the fertility of any soil, making its composition not only balanced in trace elements and nutrients, but also more loose.

Thanks to this, the roots of plants germinate deeper into the soil more easily and receive more nutrients from the earth, as well as oxygen and nitrogen from the air.

In addition, sawdust is well suited for the manufacture of soil mixture, which is used to grow high-quality seedlings.

So, why sprinkle the beds with sawdust, can they be painlessly added and what does it give in general?

Wood sawing waste contain many useful substances that increase soil productivity.

After all, all these substances extracted from the earth are integrated into cellulose, of which wood is composed.

In addition, during decay, cellulose breaks down into glucose, which is necessary for plants to grow.

Another useful feature wood waste – change in soil structure which is especially important for clay soils.

After all, the looser the soil, the easier it is to soak. aqueous solutions of fertilizers and trace elements, as well as the roots penetrate the soil more easily, creating a more powerful root system.

Sawdust is used both as a single-component fertilizer and mixed with:

• manure;
• litter;
• humus;
• sand;
• lime;
• mineral fertilizers;
• trace elements.

Read more about the preparation of fertilizers from sawdust.

But it should be borne in mind that in addition to the undoubted benefits, sawdust can also cause significant harm if used incorrectly. But we will talk about this below.

Seed and seedling care

Wood sawing waste can be used to germinate seeds and grow seedlings.

Moreover, the seeds are germinated in clean, rotted sawdust of high humidity.

Their advantage over other methods of seed germination is that wood waste resembles soil in its structure.

The seed puts out a root and a stem due to internal reserves of nutrients, and sawdust provides the root with the ability to produce shoots that penetrate into the soil.

Thereby root system rapidly developing and takes the desired shape.

During transplantation, the loose structure of wood waste allows you to extract the root without damage, so that the seedling quickly takes root in a new place.

Germination in sawdust gives the greatest effect when the seedling is placed in a soil mixture containing, in addition to soil, peat and rotted wood sawing waste.

Mulch

Used for mulching various materials including sawdust.

The main advantage of sawdust is that it shipping is cheaper than buying any other materials.

The only exception is mulch from grass plucked or mowed in its area.

Mulching with rotted wood sawing waste has little effect on the microclimate in the soil, so no active processes in the waste occur.

That is why it is impossible to mulch with fresh sawdust, because bacteria that break down cellulose consume nitrogen from the soil and release various substances that increase the acidity of the soil.

Mulching reduces the water needs of plants, because a layer of mulch separates the soil from the air and prevents moisture from evaporating.

Because of this, plants need less watering and there are no problems caused by excessive moisture in the upper layer of the soil. In addition, the less the plant is watered, the less water hits the leaves.

If the beds were mulched in the spring, then after harvesting, applying manure or litter and various fertilizersthey need to be dug up or plowed. Thanks to this, the soil will receive a portion of balanced fertilizers, and sawdust will make its structure looser.

You can read more about all these issues in the article.

Weed control

For many beds and greenhouses weeds are a serious problem, because even in imported soil their seeds are found.

In addition, many weeds throw seeds into the air, causing them to scatter over a long distance and germinate in any soil.

Chemical methods of struggle are not applicable, because it is difficult to process the weeds and not hurt useful plants and pulling them out by hand is very difficult.

So good way to combat such pests - put sawdust.

Layer of wood waste 10-15 cm thick prevents the germination of weeds, after all, at this stage, seedlings can only grow 2–5 cm due to the energy reserves in the seed. For further growth, they need both food from the ground and solar energy, the flow of which is blocked by a layer of mulch.

The type of wood does not matter, the only condition is that the waste must completely rot, otherwise it will acidify the soil and draw nitrogen out of it, which will negatively affect plant growth.

To protect the beds or greenhouse from weeds, mulch should be sprinkled in several stages:

1. At the first stage (immediately after planting the seedlings), the layer thickness should be such that the mulch does not reach the bottom sheet a little.
2. After rooting the plant and resuming its growth, add another layer of mulch.
3. The third bedding is done along with trimming the lower and unnecessary leaves (stepping). During the third bedding, the layer thickness is adjusted to the required level.

Slug Protection

The leaves of many plants are food for various slugs and snails, which eat and damage them.

Chemical control methods (including the use of tobacco) are not always applicable, so gardeners and greenhouse owners are forced to look for other ways to protect plants from these pests.

One such method is sawdust mulching.

After all, the surface of the mulch is filled with sharp fragments sticking up, which is why it is difficult for slugs to move on them.

As a result, sawmill mulch is more effective at controlling slugs and snails than grass mulch.

After all, grass, even dried up, is more convenient and familiar to slugs than a layer of sawdust.

Therefore, beds and greenhouses mulched with sawdust, reliably protected from slugs and snails, moreover, this protection prevents the germination of weeds, and after autumn and spring digging / plowing, it will improve the soil structure and fill it with the substances necessary for plant growth.

Is it possible to pour fresh sawdust?

Why are beds sprinkled with sawdust at all, and why is it believed that fresh sawdust can harm plantings?

To answer this question, you need to understand - what processes are going on in fresh sawdust and how they affect the soil and plants.

Fresh wood waste consists of cellulose and various resins, into which the juices that feed the tree trunk are converted.

When the humidity of the waste exceeds 30-50%, aerobic bifidobacteria and various fungi begin to multiply intensively in them, which convert cellulose into glucose, carbon dioxide and water.

While eating wood, these fungi and bacteria also consume huge amounts of nitrogen, some of which they get from the air. However, there is not enough nitrogen in the air, so microorganisms pull it out of the ground on which sawdust is poured.

This leads to a decrease in the level of nitrogen in the soil, which reduces the fertility of the soil, because nitrogen is essential for the development and growth of any plants.

Besides, microorganisms secrete various acids, which penetrate the soil and increase its acidity. This is good on alkaline soils if they are going to grow cucumbers, tomatoes and other plants that love acidic soil.

However, on neutral and acidic soils oh it will lead to excessive acidification and a drop in yield, as well as to frequent plant diseases.

In addition, in the process of sawdust rotting, they heat up and heat up surrounding soil. This effect is used for soil heating with early planting of seeds and seedlings in greenhouses or open ground, however, there, decaying wood waste is separated from the soil in which the plant grows with a layer of earth.

Therefore, it is impossible to pour fresh sawdust into the garden or into the greenhouse, you have to wait until they get over. This applies to both the bottom layer of mulch and subsequent layers.

The exception is the addition of wood waste to the paths between the beds, because they will be separated from the ground by a layer of rotted sawdust and will not be able to affect the soil. If you are going to completely dig up not only the beds, but also the paths between them, then it is advisable to let them completely overturn, because fresh waste will negatively affect the soil.

Dumping between beds

Despite the fact that the paths between the beds are not used for planting, sprinkling them with fresh sawdust will reduce the yield of the beds.

After all ground water, which transfer trace elements and nutrients between individual soil particles, even with low humidity will lead to the ingress of part of the acids and the outflow of nitrogen from the beds.

The exception is upper layer mulch, detached from the ground rotted wood waste.

In greenhouses it is difficult, and sometimes it is impossible to completely plow the soil, therefore, the use of fresh sawn wood residues in the top layer of mulch on the paths is justified.

However, where they regularly plow or dig up the entire area, fresh sawdust cannot be used.

After all, hitting the ground, they will reduce the nitrogen content and increase the acidity of the soil which will negatively affect the yield.

Therefore, even for filling paths between the beds, it is advisable to use prepared (rotted) sawdust.

Preparation of the mixture for addition in the spring to the greenhouse or on open ground

The method of preparation depends on how and when you are going to use sawdust.

If time permits, the easiest way is to dump them in big pile on earth and pour abundantly with solution, consisting of warm water and litter or manure in a ratio of 1:50–1:100.

For each cubic meter of sawdust, 100 liters of such a solution must be used.

Manure and litter activate bacteria and fungi, which will ensure the decay of wood waste and the whole process will take 1-2 years. If watered clean water, then the process will stretch for 2-4 years.

Such sawdust can be used for:

• mulching beds;
• additions to the soil mixture for growing seedlings;
• seed germination;
• protection of plant roots from frost;
• plant nutrition.

If you are going to make a complex fertilizer from sawdust, then they need to be mixed with droppings or manure and left to rot.

Such humus is a better fertilizer than rotted wood sawing waste alone, due to the fact that they contain many different useful substances, and the structure is close to that of black soil.

To speed up the rotting process, add drugs that accelerate the growth and reproduction of bifidobacteria. To reduce acidity finished fertilizer added to the mixture slaked lime, dolomite flour or wood ash.

Preparations that accelerate the reproduction of bacteria can also be used for clean or watered with a solution of manure / manure / dung sawing waste.

However, even with bacteria the process will take at least six months for deciduous and year for conifers.

If you need to quickly turn the sawdust into rotted, then you need to process them:

• an aqueous solution of humus or manure in a ratio of 1:20 at the rate of 100 liters of solution per 1 m3 of wood waste;
• urea solution 1:100 (10 l per 1 m3);
• slaked lime or dolomite flour (50–100 g per 1 m3);
• a drug that accelerates the reproduction of bifidobacteria (the dosage indicated on the package is multiplied by 2).

Conclusion

Wood sawing waste may be very useful material for fertilizing the soil in beds and greenhouses, however, their improper use can not only ruin the crop, but also make the land barren for several years.

After reading the article, you learned:

• how to properly apply sawdust in beds and greenhouses;
• is it possible to use fresh sawdust;
• how to prepare wood sawing waste for use in greenhouses or garden beds.

In contact with

Often, gardeners use them for mulching and warming some crops for the winter. However, not everyone knows that sawdust can also be used as a fertilizer. The pre-treated material will be fine organic top dressing- in particular, the main component of the nutritional complex natural origin.

Can sawdust be added to the soil?

Sawdust is an excellent soil softener. Thanks to them, the soil becomes much lighter, perfectly passes air and water. The rhizomes of plants begin to receive the necessary amount of oxygen, moisture and nutrients. This will certainly affect their growth, development and fruiting.

However, controversy does not subside around sawdust: some gardeners are confident in their benefits, others see one harm.

Benefits of sawdust:

• Serve as an integral component of organic complexes.
• They have excellent heat dissipation.
• Retain moisture.
• Improve soil structure.
• Does not contain weed seeds.
• Capable of repelling harmful insects.

One of the interesting advantages of sawdust is the ability to scare away the main enemy of all gardeners without exception - colorado potato beetle. This pest cannot stand the fresh resinous spirit. Pine shavings are especially hated for him.

When planting potatoes, the aisles are sprinkled with sawdust. It's pine. To enhance the effect, this should be done at least 3 times during the summer.

The most valuable organic raw materials do not allow the crop to dry out and overheat, which has a positive effect on the formation of tubers and the crop as a whole.

Sawdust damage:

• When entered into fresh they pull nitrogen out of the soil, which significantly depletes it.
• If you dump the sawdust, combining them with manure, into a pile and forget to mix, soon a fungus will start there.
• Wood shavings contain not only useful substances, but also resins harmful to some plants.
• Not suitable for dry climates.
• Fresh raw materials can lead to acidification of the soil.

Composition and properties

Overripe sawdust contains necessary for plants trace elements, essential oils, a large number of fiber and a number of other essential substances. They supply the soil with carbon, in which beneficial microbes then settle with pleasure.

Only competently processed, composted sawdust is endowed with such properties.

Pure wood shavings cannot be fertilizer. It contains too much nitrogen, cellulose, as well as resins and lignin, which impoverish the soil. This is due to the formation of countless microorganisms in the decaying raw materials that absorb the nutrition intended for plants. First of all, it pumps phosphorus and nitrogen.

At the same time, the process of soil acidification is underway.

For this reason, fresh sawdust is not recommended to be applied to the soil. Plants deprived of nutrition will simply die. But it is not forbidden to sprinkle the beds with fresh sawdust from above. They retain moisture and prevent the growth of weeds. Under strawberry bushes, sawdust is most useful: it protects the berries from rotting, weevil damage, and simply from pollution.

Coniferous sawdust not only fights pests, but also disinfects the soil. However, their composition is replete with resins that not all cultivated plants like.

Oak and birch sawdust are allelopathic - emit chemical substances that inhibit the growth of certain crops.

Manufacture of fertilizer and preparation for application

To obtain a full-fledged organic fertilizer from sawdust, it is best to compost it. There, thanks to the heat, they quickly overheat. Already in the spring, the humus is ready for laying - it is breathable, loose.

Sawdust based compost

Its preparation requires careful adherence to technology. Just pouring sawdust in a bunch and waiting for overheating will not work. They need moisture to decompose. A pile of sawdust will never get wet through. Accordingly, the process of overheating can drag on for years.

Technology:

1. Choose a place for the future compost heap.
2. Mix sawdust (1 cubic meter) pre-moistened with water or slurry, any manure (100 kilograms), chicken droppings (15 kg).
3. Plant waste, weeds, fallen leaves will only increase the process of overheating. Therefore, you can safely add them to the compost.
4. In the absence of manure, uric acid (200 g of urea per 30 liters of sawdust) or fresh mullein should be used.
5. When the compost dries out, it needs to be moistened periodically.
6. To speed up the process, cover the heap.

The quality of the compost can be improved by simultaneously laying all the components and a small part of the earth (a couple of buckets are enough). This will help earthworms and microbes do their job more efficiently.

Do not forget that sawdust in contact with weeds is likely to become an involuntary carrier of their seeds. They can be cleaned by hot composting, which deliberately increases the temperature inside the organic mass. To do this, the pile is immediately covered with polyethylene or simply spilled with boiling water.

Use in the garden and garden

It is best to use sawdust as a fertilizer late autumn or in the spring. Preparatory work may vary depending on the type of fertilized plants:

• Solanaceae (peppers, tomatoes, potatoes, eggplants) prefer the autumn introduction of fresh sawdust mixed with manure.
• Umbrellas love it too autumn top dressing fresh organic.

Carrots fertilized in the spring will respond with the formation of small, gnarled root crops.

• Melon plants favor spring fertilization. But it is better to feed them with rotted biomaterial.

sawdust for greenhouses

Their positive effect is difficult to overestimate. Sawdust is brought into greenhouses both in autumn and in spring. And in any form: plant remains, with any kind of manure, in the form of compost.

So that sawdust does not pull nitrogenous compounds from the soil, they are pre-prepared - they are allowed to overheat.

The beauty of such organic raw materials is that, together with manure and other organic matter, it warms the soil better. Plants begin to consume nutrients faster and more efficiently.



Greenhouse sawdust for the growth of cucumbers

Most gardeners tend to sow cucumbers in greenhouses early in order to quickly harvest the first crop. However, in early spring the weather is changeable, frosts can occur. Not everyone has the opportunity to put at least the simplest heater in the greenhouse in order to save seedlings from death. A proven method of warming the beds with sawdust will come to the rescue. They do it like this:

• They remove the top layer of soil, lay rotted sawdust, spill it with slurry.
• Sprinkle with the same soil and form beds.

In such an environment, cucumbers are not afraid of minor temperature changes, because the culture will have enough heat until the end of the season.

Sawdust does an excellent job with cucumber pests. It is enough just to sprinkle the trunk with a small layer of such organic matter as insects will rush to leave the plant.

sawdust for beds

Sawdust serves as the main material for the formation of beds and rid the site of an excess of moisture. When flooding the garden with showers or flooding during the period of snow melting, do this:

• a trench is dug around the perimeter (35 cm wide, 25 deep),
• they fill it with sawdust, and the earth is sent to the beds themselves - the excess water will go away.

After a couple of years, the most valuable organic fertilizer will be ready in the trench. It remains only to extract and use.

Sawdust-based fertilizer is used for:

• vegetables and berries (from potatoes to strawberries);
• garden trees;
• colors;

Potato sprouting

Many gardeners want to enjoy young potatoes already in June. In the preparation of this culture for planting sawdust has no equal.

About a couple of weeks before sending the potatoes to the open ground, the germinated tubers are placed in boxes with sawdust. From above they are sprinkled with a wet substrate. Leave indoors at +20 degrees.

As soon as the sprouts reach 7 cm, they are fed complex fertilizer and planted in the ground.

The soil must be warm enough, otherwise you will have to cover the planting with a film.

Such potatoes begin to bear fruit 3-4 weeks earlier than usual.



mushroom cultivation

In this case, fresh sawdust that has passed comprehensive training. It is recommended to take birch, oak, willow, poplar, maple, aspen sawdust for the substrate. They are suitable for creating the perfect mycelium, which will hasten to please the owners with a rich harvest.

Warming of garden trees

Fruit trees, berries require warming for the winter. Sawdust here is very welcome. They are laid out in packages, well pulled, in order to prevent the ingress of water, insects, rodents. Then they cover young trees. This type insulation has been tested over the years. There is no doubt about its reliability. It is also used to cover clematis and roses.

Grapes are warmed differently. Take a strong wooden frame, cover the plant with it, completely fill it with fresh sawdust, wrap it with polyethylene.

Organic raw materials should not get wet in the rain. Otherwise, the first frost will turn the sawdust box into an ice block.

Mulching with sawdust

Some gardeners are limited to complex compost. Others, with the help of sawdust, protect crops from freezing in winter or being attacked by dangerous pests.

It is customary to mulch plants with semi-rotted, completely rotted or even pre-prepared fresh raw materials. A layer of 5 centimeters is enough. This mulch is perfect for berry bushes, in the beds, in the thickets of raspberries.

Mulch is needed at the beginning of summer when active growth plants. It helps retain moisture in the soil. At the end of the season, the mulch mixes with the soil and becomes less visible.

Conclusion

The use of sawdust in the garden greatly simplifies the life of gardeners. They receive not only excellent fertilizer, useful mulch, but also an effective covering material. All this, along with affordable cost, makes them a very popular raw material for household plots.

Sawdust, like other wood sawing waste, is a good material for making fertilizer and compost.

However, errors in the process, which are made out of ignorance, as well as the incorrect use of ready-made fertilizer, can not only harm plantings, but change the characteristics of the soil, making it unsuitable for certain plants.

• why does the earth need fertilizers;
• how sawdust turns into compost;
• how to make compost from wood waste and litter or manure;
• how to determine the readiness of humus;
• which sawdust is best suited for getting humus;



As the plants grow, their roots pull nutrients from the ground and various minerals in the form of aqueous solutions.

These substances are concentrated in the upper (fertile) layer, consisting of:

• clay;
• sand;
• humus (humus).

During irrigation, water impregnates the top layer of soil and, mixing with these substances, forms water solution. The more intensive the growth of roots and other parts of the plant, the more strongly it draws water from the earth and an aqueous solution of nutrients and minerals.

Gradually, the concentration of nutrients and substances necessary for growth in the soil falls and the plant no longer receives them in due measure. Because of this:

• the growth rate is reduced;
• immunity decreases and vulnerability to diseases and pests increases;
• the quantity of fruits decreases and their quality decreases.

In nature, the consumption of nutrients by plants is compensated the formation of humus from various organic matter:

• dead roots, leaves and branches;
• excrement of birds and animals;
• corpses of various living beings.

In gardens and orchards, this method of renewing the fertile qualities of the land is not applicable, therefore, in the soil must be paid special formulations , which contain nutrients and substances necessary for the development of plants.

By impregnating the top layer of soil, they increase its fertility, supplying the roots of plants with the necessary nutrition and building material.

Humus production



The transformation of sawdust into humus is natural result of the work of various bacteria, which break down cellulose into simple organic substances, and also perform many other actions.

Therefore, the rate of obtaining humus, as well as its quality, directly depend on the conditions created for these bacteria.

In addition, very the composition of the source material is important- processing only one wood waste allows bacteria to make a good nutrient out of them, but does not supply the soil with substances and microelements necessary for plant growth.

The sawdust fertilizer production process starts under the following conditions:

• positive temperature and sufficient humidity;
• oxygen availability;
• the presence of a minimum number of bacteria.

For the vital activity of bifidobacteria, which break down cellulose into glucose and other substances, nitrogen is needed which they absorb from the air and the earth. The nitrogen contained in the air is not enough for the active activity of bacteria, so their activity is low.

You can increase it by adding:

• urea;
• land;
• dung or manure.

In the process of bacterial activity, a lot of carbon dioxide, so the process of turning compost into humus should only take place outdoors.



In addition, bacteria that turn sawdust into humus generate a lot of heat, so process does not stop even at sub-zero temperatures.

However, when the temperature drops, the bacteria living in the outer layer of the compost heap slow down their work, so the rotting process is less even.

But heat inside the heap allows bacteria to convert the material in the outer layers of the heap.

In addition to processed cellulose and other organic matter, the compost should also contain inorganic substances, primarily calcium and phosphorus.

Therefore, to obtain a high-quality balanced humus, it is necessary to add slaked lime and other minerals to the compost.

During the vital activity of bacteria, they mix with humus to the maximum and form compounds that are optimal for plant nutrition.

How to make rotted sawdust quickly?

For making compost free space is needed separated from the garden by a "sanitary zone" measuring 5–7 meters.

Despite the fact that you can simply dump all the materials in a heap and leave to rot, many gardeners and gardeners prefer neat boxes, which prevent compost spillage.

What is composting?



As such a box can be used ditches, platforms and any containers.

Putting compost in pits and ditches is most effective if various plants are planted over them.

In this case, the high temperature created by the bacteria will allow seedlings or seeds to be planted 3-6 weeks earlier, thereby the harvest will be earlier. In addition, a slight heating of the earth will have a beneficial effect on the development of the root system.

Depending on the type of wood, natural decay under such conditions is 1–3 years, and the rise in temperature in the compost is 1-5 degrees.

Adding manure or manure to sawdust reduces rotting time up to 6–10 months, and the addition of drugs that accelerate the reproduction of bifidobacteria reduces the period to 3–5 months.

At the same time, the temperature of the compost rises to the level of 40-60 degrees, even when the air temperature drops to zero or a slight frost.

More details about this method of obtaining humus, as well as compensation negative impact on the ground, you can read in the article about.

To get manure from compost any suitable container can be used from materials resistant to bifidobacteria and light acids. Easiest to use plastic containers suitable size.

If you only have metal barrel or box then it can be covered with roofing material, but it will negatively affect the bacteria in the outer layer.



good for making compost bin suitable wood. Although it does not serve long (5–15 years), it does not disturb the microclimate in the compost heap.

A wooden box can be made from boards or bars, or from old doors.

Sometimes the box is even made from disassembled cabinets (chipboard boards), but the phenols contained in them negatively affect the microflora of the outer layers of the pile.

In such boxes, the rotting process does not stop, but becomes a little more uneven.

Subject to the terms of decay, the humus from it is in no way inferior to any other, therefore the only drawback- you need to wait 1-2 weeks longer.

The shape of the compost bin can be any, but it is important to remember that the higher the height of the heap in it, the stronger the pressure on the walls.

It's easier to make a box bigger size in length and width, using for it thin bars and boards, than to fence a powerful structure that can withstand the pressure of a large heap.

After all, the task of such a box is prevent spillage of contents over the surrounding area.

It is not necessary to make the walls of the box completely closed, it is quite acceptable to make them in the form of a grid with a cell height of 3-10 cm (depending on the composition of the compost - for sawdust no more than 3 cm, for a mixture of sawdust and excrement up to 10 cm). Cells can be any length.



If there is no box, or you don't want to do it, you can compost right on the ground.

At the same time, you must understand that the area under the pile will receive too much nutrients and minerals, and the soil on it will become acidic.

Therefore, even next year it is undesirable to plant anything there.

After the compost has completely rotted, such an area should be sprinkled with ash and slaked lime or dolomite flour, then plowed up so that the earth can absorb nutrients, and after a year it can be used for planting.

Therefore, the area under compost heap must be chosen very carefully- if possible, close to the landing site and so as not to damage the plants.

After all, even at a distance of 2-3 meters from the edge of the pile, the concentration of acids, nutrients and minerals will be dangerous for plants.

Ways to get humus

Exist 8 compound combinations to obtain humus from wood waste, which differ both in the components used and in the final result:

• clean sawdust;
• treated with urea;
• a mixture of any parts of plants;
• with kitchen waste;
• with manure/compost;
• with the addition of the contents of cesspools;
• from wood waste, manure/compost and mineral additives;
• with the use of drugs that accelerate the reproduction of bifidobacteria.

First way simplest, but also the longest.



Wood waste is piled up and watered to increase its moisture content.

Sometimes, before stacking, the waste is soaked for 1-2 hours, but this is justified only with small volumes.

The decay time of such a heap depends on:

• tree species;
• air temperature;
• the composition of the earth below it.

Soft hardwoods rot in 10–15 months, and conifers in 2–3 years. At intervals of 2 weeks check heap humidity and temperature putting his hand into it.

If the pile is dry or cold, then it needs to be watered. If it is wet to the touch, then there is too much water in it, so the pile needs to be stirred up to dry out, then raked again.

You can speed up the process of turning compost from wood waste into humus using urea treatment.

To do this, urea is dissolved in water and this solution is poured over a bunch. The urea solution fills the wood with nitrogen, which is necessary for bacteria for normal existence, so the rate of their reproduction, as well as the efficiency of work, increase markedly.

Both types of humus, obtained from sawdust alone, contain only good nutrients, therefore, along with them need to add micronutrients. Otherwise, they will be effective only as top dressing on non-depleted soils.

In addition to sawing wood waste, you can make compost from any part of the plant. For example, in the fall, you collect leaves and rake, then form a pile by laying sawdust and leaves in layers.



If you cut trees, then cut branches grind with special equipment, which we talked about in this.

Twigs and branches big size will rot for decades, and the bacteria will process the chopped wood as quickly as sawdust.

Remember, diseased or pest-infested leaves and branches should not be allowed into the compost. Such waste should pile up and then burn.

After all, the bacteria that process wood will not be able to kill pathogens or pests, so humus from infected materials will pose a threat to your plantings.

In addition to waste from the garden or garden, you can use it to get humus and any kitchen leftovers with the exception of meat.

They can be either fresh or sour or moldy, the only condition is that all waste must be crushed , Otherwise, the process of decay will stretch for several years.

A mixture of sawdust and droppings or manure is obtained in barns, pigsties and other places where animals are kept. The most popular mixture of sawdust with chicken manure or manure.

Excrement of animals and birds not only fills the compost with nitrogen, but also are a source of many trace elements required for normal plant growth.



Such compost rots in 8-12 months.

If drugs are added to it that accelerate the reproduction of bifidobacteria, then humus will be ready in 4-6 months.

In addition, such humus is the most balanced and suitable for use on any soil for any plant.

Together with litter or manure, the contents of cesspools and street toilets can also be poured into the compost heap.

The only condition is that they shouldn't go out domestic sewerage, because water containing shampoos and washing powders is poured into it, and such chemistry negatively affects both the soil and plantings.

To create the correct heap, first lay a layer of sawdust 10 cm thick, then water it with the contents of the cesspools (1 bucket per 2–10 m 2) and lay a new layer of sawdust.

The height of the pile is chosen based on convenience and total volume.

Signs of the completion of decay are:

• completely absent smell of excrement;
• loose structure, similar to loosened sandy soil;
• lowering the temperature to street temperature both outside and inside the heap.

If you have acidic soil in your area, and plants like less acidic or alkaline soil, then stacking a compost heap, sprinkle it with slaked lime or dolomite flour..

How to apply humus?

AT agriculture humus, including from sawdust, is used in various ways.

Completely prepared humus is scattered over the site and plowed up to mix with the ground. This way most effective in early or late autumn.

If you plant green manure, then you can scatter humus both before planting and during the preparation of the field for winter.

During autumn and winter, humus and soil mix, so that plants get a more balanced diet. Ready-made humus can also be applied during spring plowing, but this method is less effective, because the soil will not have time to be saturated with humus and the plants will not receive a balanced diet.



You can also use compositions that have not had time to overheat.

If they are treated with agents that accelerate the growth of bacteria, then such compost can be applied after the collection of green manure, during autumn plowing.

During the winter, sawdust and other components will completely rot and mix with the soil.

Therefore, in the spring, the plants will receive the most balanced nutrition.

Fresh compost is applied to the soil only in three cases:

• its composition provides rapid decay and treated with drugs that accelerate the growth of bacteria;
• the field is left fallow;
• compost is used for heating planting material in pits and grooves.

In all other cases, fresh compost reduce plant yield and can make the land unusable.

In, where the soil around the trees is not dug up or is dug up very rarely, ready-made humus laid out around the trunk and watered abundantly.

Nutrients and microelements from humus, together with water, penetrate the soil and saturate it, thanks to which the tree grows faster and bears fruit better.

The same method is used for fertilizing fields planted with currants, raspberries and other bushes.

Let's figure out how to use sawdust correctly so that they will surely benefit. Sawdust is really good as a fertilizer for the garden, but there are some nuances. You should not expect a rich harvest if they were simply thoughtlessly scattered along the garden until a stable microbial community has been created.

1st method: sawdust as compost

This is how it is done, and everyone has been scared for a long time that you should not use fresh sawdust for any crops. Decaying, they will use up the available nitrogen in the soil, while expelling toxic substances. It would be much more rational to make compost from sawdust.

To do this, the bottom layer of grass or hay is first laid out in the compost tank, and then sawdust is compacted in layers of 10-15 cm. Each layer is significantly filled with a solution of water with urea, made in proportions of 200 grams of this substance per bucket of water.

Of course, mineral water can be replaced with weed infusion (there are more nettles and dandelions, but with roots) or bird droppings can be diluted. It is also good to layer each layer of 10-15 cm with earth in order to populate the compost with beneficial microbes.



When the whole pile is ready, it should be covered with a film or any material that does not allow drying. After two weeks, the pile must be poured with a shovel (transshipment should be done). After a two-month period, the sawdust will completely darken and a safe organic fertilizer for the garden is ready.

Method 2: Nitrogen Enriched Sawdust - A Quick Mix for the Lazy

There is not always time and patience to make a full-fledged compost fertilizer. Not a problem. Plants will get excellent nourishment from sawdust from raw wood mixed with nitrogen fertilizer prepared in any of the following ways:

• 20 grams of urea per kilo wood chips;
• 0.5 liters of solution bird droppings on a bucket of water;
• 3 liters of weed infusion for 7 liters of water.

You can mix dry sawdust with urea in advance, or first scatter them on an empty garden bed and spill it with a solution - it doesn’t matter. After a while, the ground covered with sawdust can be processed as usual. Enriched sawdust is great to use when laying high beds - they give looseness to the soil, improve moisture capacity.

Whoever has a little sawdust, you can enrich them with home remedies - rinse the bowl from the preparation of the dough for the jellied pie (another name is "charlotte") and soak the sawdust. The wash from the dough contains everything you need - the remains of eggs, flour, sugar. Soil biota will definitely be delighted with such a freebie. By the way, it is not a sin to powder the soil in pots of home flowers with such sawdust - evaporation from the soil surface will decrease, transpiration jumps will smooth out.

3rd way: enrichment of fresh sawdust with EM cultures

Wood sawdust as fertilizer for the garden can be enriched with EMs. It doesn't matter if it's purchased or homemade. We cook just like OFEM in this video of charming Valeria Zashchitina:

4th method: a mixture of fresh sawdust with compost or manure

Potatoes, tomatoes and carrots can be fertilized with sawdust interspersed with organic fertilizers. In this case, it is better to shower them on the ground autumn sometimes.

As for cucumbers, cabbage, gourds, then fertilize them in this way, preferably in the spring, mixing with farm animal manure and ash.

5th method: mulching the soil with sawdust

As already mentioned, due to the many publications, novice summer residents doubt whether it is possible to mulch with fresh sawdust. It seems to us that such articles are incomplete and scare beginners in vain. sawdust - beautiful natural material, and to refuse such cheap organics is simply a sin. By the way, such a wonderful fertilizer as lingohumate is obtained from wood waste. Haven't tried? Try at least on seedlings.

How sawdust mulch will remarkably protect the soil from adverse weather conditions and drying, because they perfectly retain moisture. In addition, many rooted weeds will not be able to break through their stratification.



After a year, the sawdust will rot without a trace, saturating the soil during this process. nutrients which will ensure a good harvest. In the next season, it is advisable to take care of the plants by soaking sawdust mulch with aerated compost tea or weed solution.

To avoid trouble

And, as usual, having considered all the advantages, we must still recall the harm of sawdust to the soil. There are not so many cons. For example, do not sprinkle the soil around the plants with sawdust of unknown origin. Varnishes, glues, carcinogens and other chemicals they contain can kill crops or ruin expected crops. If a mistake has already been made, all the beds should be generously watered with rotten humus. It will gradually cleanse the soil of unwanted substances.

The second warning is also quite simple - softwood sawdust contains organic resins, and they acidify the soil. It is desirable for them to mulch the soil near rhododendrons, blueberries and heathers. Or add deoxidizers - dolomite flour, ground eggshell and/or wood ash.

Third - sawdust of poplar, oak, walnut known to be allelopathic. That is, their excretion inhibits the growth of many cultivated plants. But do not throw away such organic matter! It is better to accumulate sawdust, shavings and foliage of these tree species somewhere separately (bag, box, etc.), spilling them with EMs or urea and calmly use them in a year or two.



By this time, the natural colins will have weathered out, the waste will be saturated with natural organic acids, saprophytes will develop in it, and the entire armada of soil biota will pounce on these sawdust when you distribute it in the garden.

Here are some ways to use sawdust in the garden. So do not be afraid of incomplete publications, and do not try to collect and take sawdust in the country somewhere, and even more so burn it - this is blasphemy! We hope excessive emotionality the article did not prevent you from understanding how you can use sawdust for the garden - the benefits and harms of their use in the country have become obvious.

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.
