It is made by grinding dolomite stone. This mineral is very common in our country. Today, its production volumes are quite enough to fully meet the needs of the state. Used this product in many areas National economy- in construction, animal husbandry, road construction, in the glass and paint and varnish industries. It has found its widest application in agriculture. How to properly use dolomite flour on suburban area and we'll talk further.
These funds are used primarily to improve acidified soils. That on such a land it is impossible to obtain good harvest practically from no culture, it is known, probably, to all summer residents. The fact is that the roots of plants in acidic soil very poorly absorbed nutrients. Even the application of fertilizers and an increase in the "fat content" of the earth does not change the situation. One of the most effective means used to neutralize acidic soil is just dolomite flour. The use of this tool in the fall for digging is a great way to increase crop yields for next year. Limestone flour is applied in certain doses, depending on the degree of acidification of the site.
Among other things, dolomite flour helps to loosen the soil and enrich it with useful minerals. For example, it contains a lot of calcium. This substance has an unusually beneficial effect on the root system of plants, increasing the efficiency of its work. Horticultural and horticultural crops begin to digest faster and easier different forms substances such as nitrogen, phosphorus, molybdenum, potassium. Dolomite flour also contains magnesium. It is able to stimulate photosynthesis. This substance also has a beneficial effect on the vital activity of various microorganisms useful for plants.
The ability to prevent a decrease in yield as a result of damage to crops by certain types of insects is also one of the useful qualities of a fertilizer such as dolomite flour. The use of this substance in autumn will lead to the destruction of the chitinous cover of beetles and worms wintering in the ground. This white dust has a particularly strong effect on the hard integuments of insects at the points of their articulation.
Another interesting property dolomite flour is that it is able to bind radionuclides. Therefore, after introducing it into the soil, you can get a much more environmentally friendly crop of horticultural and horticultural crops. It will keep much better.
In the event that the soil has an acid reaction over the entire area of \u200b\u200bthe site, it is worth filling it up in the fall. dolomite flour fully. In this case, it is important to correctly calculate the required amount. The dosage depends largely on the composition of the soil. So,
If the soil on the site is loose and light, the dose should be reduced by 1.5 times. On heavy dense soils, on the contrary, it is increased (by 10-15%). The flour should be distributed throughout the garden as evenly as possible. Leveling is done with a rake. Then the soil is dug up on the bayonet of a shovel. Re-treatment of the site will need to be carried out after about 8 years.
Next, let's figure out when exactly dolomite flour can be introduced into the soil. The use of this fertilizer in the fall, as you already understood, is most appropriate. You can apply it to the soil in the spring when planting or even in the summer. However, it is the method of improving the soil with its use before winter that is considered the most effective. Usually, on light soils, dolomite flour is applied to the soil once every 2 years, on heavy soils - once a year. It is best to improve the soil with it in August-October, after harvesting this particular crop. Of course, it is important to observe the correct dosage. For example, in trunk circles currant flour is usually applied in the amount of 500 g per bush. For cherries and plums, it is also used in the fall in the amount of 1-2 kg per plant. If necessary, you can use this tool twice a year - both in spring and autumn.
Next, we will deal with exactly which plants limestone flour should be applied under. Dolomite flour, the use of which in the fall is a very effective procedure, can be used to increase the yield of almost any garden crop. From fruit trees stone fruits respond best to this substance. Also, when using it, the yield of vegetables is significantly increased. This method of improving the soil is most effective on cabbage. Also, this tool is often used to increase the yield of tomatoes, eggplants, peppers and potatoes. It is worth making flour for legumes, salads, barley and cucumbers.
In autumn, dolomite flour should definitely be sprinkled under everything. It can be garlic, winter onions, decorative garden plants etc. According to the results of research conducted by scientists, the use of lime flour can increase yields by 4-12%. The most noticeable effect from its use is manifested approximately one or two years after being introduced into the soil.
Of course, there are plants that do not respond too well to a substance such as dolomite flour. The use of this remedy in autumn or at any other time of the year under gooseberries or sorrel is not recommended. Do not use it under cultivated plants and if the soil on the site has a neutral or alkaline reaction.
It is also necessary to combine dolomite flour with other fertilizers correctly. In order to enhance the effect it produces, you can use it simultaneously with boric acid or with other substances containing them in their composition. Do not mix limestone flour with urea and ammonium nitrate. It does not mix well with manure either. Since the latter is used very often for plant fertilizer, it is still used simultaneously with dolomite flour. However, one must follow one important recommendation. In autumn, dolomite is scattered over the bed and only then manure. Then everything is dug up.
As already mentioned, most often limestone flour is used in the fall. When buying it, be sure to pay attention to quality. It is determined by the fineness of the grind. In addition, it also depends on the raw materials from which the flour was produced. Depending on these two factors, lime flour is divided into classes and groups. In agriculture, rather small (with particles up to 1 mm) dolomite flour is usually used. As a fertilizer, you can also use its burnt version. Such flour has the advantage over ordinary flour that magnesium is better absorbed by plants from it.
As you can see, limestone flour is a useful fertilizer and does not have any side effects on plants. negative impacts. Of course, only if correct use. The effectiveness of the use of dolomite flour is directly dependent on the correct dosage. Before applying this fertilizer, it is imperative to conduct research on the level of soil acidity. At pH greater than 6 is unnecessary. Do not use flour in combination with incompatible fertilizers.
Receive high yields and chic flowering plants The right soil helps. To do this, you need to determine its composition. In this article we will tell you how you can do it yourself in a country house or in an apartment and change the structure of the soil.
A mineral with a crystalline structure is called dolomite. It has a glassy luster and can have a different color: brown, reddish, white, gray.
If this mineral is ground, then flour will be obtained, which contains calcium and magnesium.
When making flour into the ground, the plant has advantages:
Disadvantages:
Pros:
Disadvantages:
Lime normalizes soil acidity. It should be applied once every 5 years. With active operation, the procedure is done more often, after three years. You can determine the frequency of lime application by analyzing the soil. In this case, you can use an indicator, a special device, or determine its acidity using grape juice and vinegar essence.
If the soil is covered with horsetail, wormwood or green moss– this is the signal to apply lime without any determination of acidity.
Autumn is a good time for this.
Partial processing is carried out in the spring. That is, during this period of time it is necessary to make a small amount of lime. The procedure is done 7 days before planting seeds or seedlings.
The frequency of application of lime is influenced by the applied fertilizers. Let's say we use only mineral fertilizers, then in this case liming will be more frequent.
Again, if the applied fertilizers are natural, then they themselves regulate the neutrality of the soil, without additional liming.
Lime is used to treat tree trunks which is pest control. Usually gardeners do this in autumn and spring.
There is no single answer when choosing dolomite flour or lime. But if we talk about the composition of calcium in products, then it is 8% less in lime. But it is he who improves the structure of the soil and forms the root system.
Next element magnesium. Part lime is he Excluded, a in dolomite flour, its content reaches up to 40%. The full passage of plant photosynthesis is due to the magnesium content in chlorophyll.
Magnesium deficiency affects:
Gardeners, for example, start from a crop that will grow on soil. In their opinion, if potatoes are planted, it is better to use dolomite flour. Since the nightshade family loves magnesium, which helps fight scab. The causative agent of this disease is a radiant fungus. A favorable environment for it is soil rich in calcium.
If your plantings are missing something and fertilizing isn't helping, they may not be suited for the acidity of the soil. In too acidic ground root systems plants cannot absorb nutrients, so fertilizer is not beneficial.
Then they turn to such a measure as deoxidation; make it by adding dolomite flour to the soil. This substance is ground rock, which contains substances useful for planting - potassium and magnesium. It is cheap (about a hundred rubles for a five-kilogram bag), environmentally friendly.
In addition to deoxidation of the earth, a lot speaks for the use of fertilizer, since it:
You can understand that the earth needs deoxidation without resorting to help special devices(although these are available to the owner of the site). There are three main ways.
First, you need to observe which plantings are comfortable to exist in this area. If buttercups and plantain, and possibly wheatgrass, coltsfoot and chamomile grow on the ground in a “violent color”, this is a sign of increased acidity. Plum, cherry and apricot develop poorly on such soils.
Secondly, a little vinegar can be poured onto a handful of "experimental" earth - if a reaction occurs and foam appears, the soil also has increased acidity.
Thirdly, a good natural indicator is grape juice. A handful of acidic earth placed in a glass of juice causes the liquid to change color.
All plantings can be divided into 4 groups according to their need for acidic or alkaline soil.
Beets and alfalfa grow well only on neutral and alkaline soils, as well as stone fruit trees.
Prefer neutral soils onion, lettuce, legumes and agricultural crops (barley and wheat). If the acidity is slightly increased, nothing can be done with the soil, but strong acidity must be neutralized.
Grows equally well in acidic and alkaline soils following plants: tomatoes, radishes, other crops not mentioned in the previous paragraph. Such plants respond well to liming with powder.
Only flax and potatoes require liming in highly acidic environments; it is recommended to fertilize the soil for potatoes with a mineral in combination with substances of the potassium group, otherwise scab appears on the tubers.
The use of analogues makes sense only if they are at hand, since their spectrum of action is different in the general complex, although they are not bad for deoxidation only.
The first and most famous analogue is lime powder, which was used to reduce acidity before the introduction of dolomite. Limestone top dressing works in a similar way, the only drawback is that it will interfere with the first time after application. beneficial substances and minerals (especially phosphorus and nitrogen) are absorbed by plantings, therefore it is usually brought in “before winter”, between the beds. While dolomite powder can be used when needed.
Wood ash neutralizes acidity as successfully as dolomite, but at the same time, the consumption is many times higher, and, as a result, the treatment of plantings with ash is more expensive.
About how to use the fertilizer so-called dolomite flour, the next few chapters.
If the gardener has determined that this area requires deoxidation, you can use the following instructions as a base, and from these numbers to carry out further calculations.
Proportions of making dolomite
All values are given in the calculation of fertilizer per 1 weave.
Up to 50 kg of dolomite flour is added to soil with high acidity (if you use instrument measurements, then a figure will come in handy - the pH value of such soils will be 4.5 or less).
Medium acidic soil (with a pH value of up to 5.2) requires dolomite fertilizer in the amount of 45 kg.
In slightly acidic soil (its pH is a maximum of 5.7 units), no more than 40, and often 35 kg of powder are applied.
It should be noted that for heavy clay and loamy soils, these figures are divided by a factor of 1.5, and for light ones, they take 15% more dolomite.
The mineral can be applied at any time of the year if necessary. If a gardener or gardener also uses other fertilizers (see below for compatibility with them), then the use of this substance will have to be regulated.
Stone fruit trees are fertilized annually in the fall - after the crop is fully harvested: about 2 kg per tree will be required.
Cabbage and turnips in the garden also require annual fertilizers with dolomite: in the amount of 0.5 kg per 1 sq. m it is made immediately before planting.
Blackcurrants, like cherries and plums, are fertilized in the fall after harvesting the fruits - but for currants, the frequency of treatment will be less: only once every two years.
Is it possible to apply dolomite flour as a fertilizer for soil deoxidation in closed ground? Yes. Such an application has a so-called sanitizing effect on the soil, that is, it destroys insects harmful to plants and activates the vital activity of worms (which increase the overall fertility of soils).
The substance as a top dressing is applied to greenhouse soil in spring: it helps to disinfect the earth, as this substance prevents the development of fungal and mold diseases in plantings. It has been noted that greenhouse plants planted on soil that has been treated with such flour not only develop better, but also produce fruits with better preservation.
Powder is applied in quantities from 200 grams per 1 sq. m, while the soil is not dug up, since high humidity environment and without it contributes to the good absorption of the mineral.
The mineral is good not only as top dressing: it is abundantly fertilized with compost and especially vermicompost (biologically active compost). Worms in the latter die if they are in an environment with hyperacidity; if you deacidify the compost, bringing it to a normal pH value, they will feel comfortable, multiply quickly and efficiently process organic matter.
1 kg of powder mixed with 8 grams of powder boric acid, distributed over the treated surface and dug up. After 10 days, all the remaining minerals necessary for this soil are added and dug up again.
2 kg of fertile land is mixed with 30 grams of flour, 4 liters of peat are added, 1 liter river sand, two glasses of coal or ash, 30 grams of double superphosphate. This mixture will be the basis for the soil for indoor and greenhouse plantings; at the same time, it is necessary to add a substrate to it precisely for those plantings for which the soil is being prepared.
Dolomite powder is preferably used simultaneously with blue vitriol- these substances complement each other, mutually reinforcing the action. It is also good to use it with boric acid.
Dolomite flour is not compatible with most dressings; among them manure, urea, nitro - and azofoska, superphosphate, ammonium nitrate and ammonium sulfate. If any of these substances still needs to be applied, you just need to wait at least ten days from the moment of fertilizing with dolomite: then no destructive chemical reaction will not happen.
In clay and other heavy soils, dolomite should be applied annually, and remember that such lands require an increase in the amount of flour. The full effect of flour on this site will end in eight years.
Light sandy and peat soils require fertilization with flour every three years.
Having diluted 200 grams of powder in a ten-liter bucket, gardeners get liquid fertilizer, which can be watered plants in late spring and early summer.
To get the most out of using flour, it is mixed into the topsoil, digging up and loosening it about 15 cm deep; scattered over the surface of the site, it will begin active action in a year.
Gooseberries, sorrel and blueberries are never fertilized - the mineral has a negative effect on these plantings.
Greatest Benefit the powder will begin to bring in the second - third year after the first application - this should be remembered and the dosage should not be increased without special reasons.
The undoubted plus of the mineral is its environmental friendliness; as it is just a powder obtained from rock, it cannot be classified as a chemical. While it also plays the role of insecticide and pesticide, destroying harmful insects, as well as mold and fungal diseases- analogue among natural, not chemical substances he just doesn't.
Dolomite flour is the most popular and effective tool to quickly reduce the acidity of the soil. Low consumption, environmental friendliness and low cost are the main advantages of this substance. In this article, we will explain what dolomite flour is and how to use it in gardening.
Dolomite flour has proven to be a convenient natural remedy to reduce soil acidity. It is a crystalline carbonate mineral with a characteristic luster and light color from white to grey. In some cases, the flour may acquire a reddish and even brown tint. Dolomite flour is obtained industrially by crushing the dolomite mineral into small pieces. The tool is popular not only among summer residents, but also lovers of home gardening. Unlike the most well-known means for reducing soil acidity, dolomite flour is not so expensive, and its consumption is much less. So, slaked lime, containing a calcium ion and a hydroxyl group, “deacidifies” the soil too much and sharply, as a result of which plants cannot adapt to new conditions and absorb phosphorus very slowly. For this reason, lime should only be applied to autumn period when the crop is harvested, and the earth has time to come into relative chemical equilibrium before the next gardening season. Wood ash is another powerful way lower acidity. It contains from 30% to 60% calcium salts, but the problem is that it is impossible to know the exact composition. It depends on the type of trees used for the production of ash, on the parts of the plant that went into processing (roots, trunk, branches), on the nature of the soil and the climatic conditions of the area where these trees grew. Calculate the exact amount of ash at home without chemical analysis absolutely impossible, so you have to act at random. Most often, the ashes are used for seedlings and indoor plants because it contains a sufficient amount of potassium, magnesium and phosphorus. In both cases (lime and ash), fertilizer is required 2 times more than dolomite flour, if we consider the same unit area. Properties of dolomite flourDolomite flour is a powdered dolomite. It is a mineral with a high percentage of calcium. Over time, after long-term use of soil for cultivation fruit crops her Chemical properties are deteriorating, so replacement of the lost elements is required. The addition of dolomite flour allows you to maintain required level hydrogen and calcium ions artificially. When lime meal enters the fertile soil layer, it not only neutralizes its acidity, but also enriches micro and macro elements useful for plants. How and when to make dolomite flour? The main advantage of the fertilizer lies in its versatility - in addition to the fact that flour can be applied at any time of the year, it helps to improve the yield of almost any crop: berries, vegetables, fruits, cereals and even flowers. Moreover, lime flour fertilizer gives the same positive effect in the garden for fresh air, and in greenhouses or at home on the windowsill. Particularly effective in sandy soils and soils with a low magnesium content. It is not recommended to use flour on soil with neutral acidity, since in this case it can only upset the natural physico-chemical balance. What effect does flour have after being applied to the soil:
Dolomite flour is known as an effective pest control agent with absolute non-toxicity in relation to the soil and horticultural crops. The smallest particles of flour act as a highly irritating abrasive, destroying the chitinous shells of insects. The use of dolomite flourTo determine required amount dolomite fertilizer, you should find out the acidity of the soil in the area and its mechanical composition (sandy, clay, light, heavy, etc.). To do this, it is recommended to use the appropriate devices and disposable tests, which are sold in any gardening store. The acidity of the soil is expressed in pH and is indicated by numbers from 0 to 14. There are three types of acidity:
You can measure the acidity of the soil at home: The effectiveness of the use of dolomite flour will increase if it is added simultaneously with copper sulphate and boric acid. And one more useful video that will help you determine the characteristics of the soil before deoxidizing the soil with dolomite flour: How to fertilize the earthDepending on the acidity of the earth, dolomite flour should be applied to the soil in different proportions. So, in acidic soil, you need to add about 600 g per sq. m, in neutral - up to 500 g per sq. m, in slightly acidic - up to 350 g per sq. m. If you're dealing with the lungs sandy soils, reduce this amount by 1.5 times, if with heavy clay - increase by 10-15%. Helpful Hint: To increase the effectiveness of lime meal, try to distribute it as evenly as possible on the ground. The benefits of properly spread fertilizer will last for 7-10 years. It should be borne in mind that plants may respond to flour application in different ways. Based on this, garden and horticultural crops divided into several groups:
Features of soil fertilizer
Get ready for the fact that the positive impact of dolomite flour will not appear immediately, but gradually. It begins to bring the greatest benefit on the 2nd and 3rd year after liming the soil, increasing crop yields by 5-15%. We hope this article helped you figure out how to use dolomite flour in the garden to always get rich harvests. |
The quality of the soil greatly affects the yield. Of course, there are cultures (and there are many of them) that prefer an acidic environment. However, the vast majority of modern agricultural varieties and hybrids are designed for growing in soil with low acidity.
The use of dolomite flour in the garden helps to bring the acid-base balance of the soil back to normal. The use of this natural mineral, among other things, also improves the structure of the soil, creating more perfect conditions for growing fruit crops.
And at the same time, the use of dolomite flour in the garden must be accurately dosed. Perhaps this is only after measuring the level of acidity. To determine the actual pH of the soil, the usual experiment with litmus paper is suitable.
The structure of the soil also matters when choosing a dosage. For heavy, compacted soil, the dosage can be increased by a quarter of the indicated amount. And light soils need to reduce the volume of dolomite flour by half.
Liming the earth in autumn is more justified due to the fact that dolomite flour does not act immediately, but only after it has penetrated into the deeper layers. garden soil. Melting snow contributes more to this process.
Dolomite flour should be distributed evenly over the site. Then you need to carefully dig the garden. Or cover the flour with earth so that upper layer soil was at least 10 cm. Mixing dolomite flour with other fertilizers is not worth it. Especially dangerous is the combination with urea, superphosphate or ammonium nitrate.
Such an operation can be carried out no more than 1 time in 5-7 years. Maximum effect from the use of dolomite flour is achieved for 2-3 years after its introduction into the soil. It is permissible to add a small amount of boric acid to the dolomite flour powder (7-8 g per 1 kg of flour). This microfertilizer promotes the formation more ovaries on and reduces the likelihood of diseases in root crops.
The introduction of dolomite flour under the bushes of cherries and plums positively affects the yield. It is permissible to add up to 2 kg of flour to the soil under the trees. Currant bushes also respond well to the deoxidizer. For them, about 500 g of fertilizer is enough per bush, scattered in the fall once every 2 years.
Many gardeners know how to use dolomite flour in the garden to grow flowers. , and violets are more susceptible to the effects of dolomite than others.
To improve the soil for flowers - you need to add a small amount of dolomite flour directly to the hole before planting flower bushes. In the spring, flour is also introduced for planting turnips and. This technique allows you to get more large fruits as soon as possible.
The use of dolomite milk has also received good reviews. Regular watering of the beds with a weak solution of dolomite mixed with water, when watering in the spring and early summer, contributes to a more active vegetation of plants.
Dolomite flour is applied in the spring for digging and, if used as autumn fertilizer garden of phosphate rock. This method of fertilizing the soil is especially effective in those areas that have not been used for a vegetable garden for several years.
Well, in the end, we invite you to watch a video that tells and shows some of the principles of using dolomite flour in the garden:
