Dolomite flour is a finely ground rock used as fertilizer. Raw materials for making flour contain calcium and magnesium in large quantities. These minerals are essential for improving the physical and chemical properties of the soil. Calcium ions can artificially reduce the acidity of the soil. Dolomite formula: CaMg (CO2).

Dolomite is a rock.

Soils with high acidity are of little use for growing useful crops. Natural minerals help improve the properties of the soil, change its composition. Dolomite flour contains calcium and magnesium. Calcium has a beneficial effect on root system plants, reduces the acidity of the substrate. Magnesium is involved in photosynthesis.

Regular use of dolomite flour allows you to increase yields, intensify the growth of useful crops. With excessive acidity, the effect of other mineral fertilizers is neutralized. After adding dolomite flour, the digestibility of nutrients by plants is improved.

We measure the acidity of the soil

To avoid causing harm, you need to know how to use lime fertilizer. Before adding it, it is necessary to check the acidity of the substrate. Based on the test results, it will become clear in what quantity to add dolomite flour, and whether it is worth doing. The easiest way to independently test the acidity of the soil is to test using litmus paper.

There are ways to roughly determine the acidity. Their use is advisable if there is no litmus paper at hand. The easiest way is to pour vinegar over the ground. To do this, you need to take a small amount of soil from the garden, place it in a glass. Pour some vinegar on top. If foam appears on the surface of the substrate, then the earth has a very low acidity. If the liquid is completely absorbed, then the earth is very acidic.

Determine acidity on garden plot you can by looking at the growing weeds. Woodlice and plantain take root well on acidic soils. Neutral soils are attractive to nettles and quinoa. Chamomile and dandelion grow well on an alkaline substrate. If some of these plants predominate on the site, then you can understand whether dolomite is necessary for the earth.

Determine the amount of fertilizer

Having determined the acidity of the soil on the site, you can add flour. For increased acidity (pH less than 4.5), 500-600 grams per 1 sq. M. Is required. With an average value (pH 4.5-5.2), 450-500 grams per square meter is enough. If the soil is weakly acidic (pH 5.2-5.6), then the amount of dolomite flour should not exceed 350-450 g per 1 sq. M.

When the acidity is neutral (pH 5.5-7.5), it is sometimes necessary to add mineral flour. It all depends on the crops that are planned to be planted on this site. It is impossible to increase the amount too much per 1 sq. M., As the acidity can be greatly changed, and this will negatively affect the quality of the soil.

The fertilizer package contains instructions for use. It is recommended to add acidity-changing flour to the soil no more than once every three years. This is best done in the fall, since the main components of flour enter into a chemical reaction with the elements that make up the soil. By spring, all chemical reactions cease, and the earth acquires the necessary qualities.

results

After using dolomite flour, physical and Chemical properties soil. The dolomite composition enriches the sandy soil with magnesium. As a result, the assimilation of nutrients from the soil by plants is improved. The quality of the grown products increases, its safety improves.

The use of ground dolomite in the garden helps to neutralize slugs, which can spoil most useful crops. The product is not toxic, and the desired effect is achieved due to the structure of the flour. The smallest particles of calcium destroy the chitinous covers of pests, as a result of which the insects die.

It is useful to add dolomite flour under garden trees and shrubs. For trees with stone fruits, the amount of fertilizer should be 1-2 kg. The introduced ground dolomite must be distributed around the shaft. It is not necessary to wait for the pre-winter period to fertilize the trees. Soil enrichment with calcium can be carried out immediately after harvest.

Black currants and raspberries can be fertilized in late summer or autumn once every 2 years. For each bush, it is necessary to add 0.5-1 kg of the mineral. The exact amount depends on the size of the bush and the frequency of fertilization.

Advantages

Limestone, charcoal and some other substances resemble dolomite flour in their properties. However, ground rock has advantages over other fertilizers. Its application contributes to the fastest and most accurate soil deoxidation. This result is difficult to achieve when using wood ash, since the amount of calcium in this substance fluctuates and depends on many factors. Lime fluff deoxidizes the substrate well, but its incorrect dosage can cause plant burns.

Every gardener who wants to increase his yield knows what dolomite flour is. There is a low price for this fertilizer in stores, so anyone can use ground dolomite for use on their site.

Soil quality greatly affects yield. Of course, there are cultures (and there are many) that prefer an acidic environment. However, the vast majority of modern agricultural varieties and hybrids are designed for cultivation in low acidity soil.

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. This is possible only after measuring the acidity level. To determine the actual pH of the soil, a routine litmus test is suitable.

• For strongly acidic soils, the pH of which is less than 4.5 units, you will need 600 g of flour per 1 m 2;
• For moderately acidic soils with a pH of 4.5-5.2, 450 g of a deoxidizer per 1m 2 is required;
• For slightly acidic soils, with a pH level of 5.2 - 5.6, it will be enough for square meter only 350 g.

Soil structure 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.

Rules for the autumn introduction of dolomite flour into the soil

Liming the earth in autumn is more justified due to the fact that dolomite flour does not act immediately, but only after it penetrates into the deep layers of the garden soil. Snow melting contributes to this process to a greater extent.

Dolomite flour should be evenly distributed over the area. Then you need to carefully dig up the garden. Or cover the flour with earth so that the topsoil is at least 10 cm. Mixing dolomite flour with other fertilizers is not worth it. The combination with urea, superphosphate or ammonium nitrate is especially dangerous.

Such an operation can be carried out no more than 1 time in 5-7 years. The maximum effect of using dolomite flour is achieved 2-3 years after it is introduced into the soil. It is permissible to add a small amount of boric acid (7-8 g per 1 kg of flour) to dolomite flour powder. This microfertilizer promotes the formation of more ovaries on and reduces the likelihood of diseases in root crops.

The introduction of dolomite flour under cherry and plum bushes has a positive effect on 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 a deoxidizer. For them, about 500 g of fertilizer per bush, scattered in the fall every 2 years, is enough.

Rules for spring use of dolomite in the garden

Many gardeners know how to use dolomite flour in their 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 added for planting turnips and. This technique allows you to get larger fruits in the shortest possible time.

The use of dolomite milk 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 in the case of using phosphorite flour as an autumn fertilizer for the vegetable garden. This method of fertilizing the soil is especially effective in those areas that have not been used for gardening for several years.

VIDEO: features of making dolomite flour

Well, at the end, we invite you to watch a video, in which it is told and shown about some of the principles of using dolomite flour in the garden:

Dolomite flour is called crushed dolomite - rock formation, whose chemical formula looks like CaMg (CO2). This is an effective tool for reducing the acidity of the soil, the main advantages of which are, first of all, an affordable price and environmental friendliness. It is thanks to this that the fertilizer described in the article is very popular among the owners of suburban areas.

Dolomite flour is a convenient way to reduce soil acidity. The substance is a crystalline mineral with a light color (gray or white, less often reddish) and a characteristic luster.

A feature that favorably distinguishes dolomite chips from other means of similar action is not only lower cost, but much lower consumption. Moreover, slaked lime, for example, which contains a hydroxyl group and a calcium ion, reduces the acidity of the soil too sharply, as a result of which plants that are unable to get used to such conditions begin to absorb phosphorus extremely slowly. That is why lime is applied exclusively in the fall after harvesting - in this case, the soil will still have enough time to find chemical equilibrium for the new gardening season.

Another powerful acid lowering agent is wood ash... The concentration of calcium salts in it - the main active ingredient - ranges from 30-60%, but the difficulty is that it is not possible to determine the exact composition. The concentration of calcium salts depends, first of all, on the rock from which the ash was produced, on which parts of the plants were used (branches, trunk, etc.), as well as on the characteristics of the soil and climate conditions in that region, where these trees grew. Independently, without resorting to chemical analysis, it is impossible to accurately determine the required amount of ash, which means that people act at random. By the way, ash is usually used for seedlings and flowerpots, since it contains a lot of phosphorus and potassium.

Note! The volume of ash or lime should be approximately two times that of dolomite flour, assuming the same area.

How dolomite affects the soil

In the described fertilizer, as noted above, a large percentage of calcium. If the soil is used for a long time for fruit plants, then it deteriorates over time. chemical characteristics, which means that the lost elements must be replenished somehow. The use of dolomite flour makes it possible to artificially maintain the required concentration of hydrogen and calcium ions.

Penetrating into the soil, this fertilizer not only normalizes its acidity, but also enriches the microelements necessary for plants. But when and how should fertilization be applied? One of the differences of the mineral is its versatility: not only can you fertilize the site almost all year round, but flour also increases the yield of all crops: vegetables, fruits and grains. Finally, the effectiveness of fertilization is equally high in the garden, in the greenhouse and even in the house (when it comes to indoor plants).

But the remedy is especially effective on:

• sandy loam soil;
• soil with a low concentration of magnesium.

As for the soil with a neutral pH level, it is better not to use flour here, since this can cause a disruption of the natural chemical balance.

Fertilizer applied to the soil has the following actions:

• improves its biological characteristics;
• improves plant photosynthesis;
• increases the concentration of various minerals and trace elements that are necessary for plants;
• helps to bring out environmentally friendly products;
• increases the effectiveness of other means applied to the soil;
• improves productivity;
• improves the nutritional quality of crops;
• finally, due to the presence of calcium in its composition, flour activates the development of both ground and underground parts (rhizomes).

Note! In addition to all this, dolomite flour is an excellent remedy for harmful insects, while being absolutely non-toxic. Small particles of the product act as an irritating abrasive that destroys the chitinous shells of insects.

Methods for determining acidity

In order to determine the required amount of fertilizer, you must first find out what is the mechanical composition of the soil (for example, clay or sandy) and the level of its acidity. Usually, one-time tests or other special devices (for example, the KS-300V soil analyzer) are used for this, which are sold in all gardening stores.

Acidity is expressed in pH, it is indicated by numbers from 0 to 14 and can be:

• weak (more than 7);
• neutral (pH is 7);
• high (less than 7).

By the way, it is possible to determine the acidity of the soil with the help of improvised means.

Determination of soil acidity by improvised means

Method number 1. Pour a small amount of vinegar onto a handful of earth.

If, as a result, a violent reaction begins with the formation of foam, then the earth is either neutral or non-acidic.

The absence of a reaction (vinegar is simply absorbed into the soil) indicates that the acidity is increased.

Method number 2. A lump of earth must be dipped into a glass of grape juice.

If the color of the contents changes, and bubbles form on the surface, then the soil is either neutral or slightly acidic.

Method number 3. Weeds will not grow on soil that is not suitable for their acidity level. That is why they can be used as a kind of indicators that indicate the pH level.

On soil with weak acidity, coltsfoot, clover and wheatgrass grow.

On soil with neutral acidity - nettle, quinoa.

If the acidity is high, then plantain and wood lice will grow on the site.

Note! The efficiency of the fertilizer will increase markedly if boric acid is added with it in combination with copper sulfate.

One useful video material that can help in determining the properties of the soil before the deoxidation procedure.

Dolomite flour how to use in the garden

The specific proportions of the mineral depend on the acidity level. So, about 0.6 kg / m² should be added to acidic soil, if it is slightly acidic, then no more than 0.35 kg / m², and if neutral, then a maximum of 0.5 kg / m². If the soil is sandy on the site, then the amount of flour should be reduced by one and a half times, and if it is clayey, it should be increased by about 15%.

Note! You can increase the efficiency of fertilizer by distributing it as evenly as possible. If the flour is sprinkled correctly, then the benefits from it will be enough for about eight to ten years.

Do not forget that plants react differently to the application of the product. In this regard, cultures can be conditionally divided into several groups.

Table. Plant groups by sensitivity to acidity

When to fertilize?

As noted above, the described fertilizer can be used regardless of the time of year, since it does not in any way affect the composition of the soil or the intensity of assimilation of other nutrients. But in most cases, flour is sprinkled before using other fertilizers, since it does not organically interact with all of them.

If vegetables are grown on the site, then dolomite flour is crumbled in the spring, two to three weeks before planting. This tool not only nourishes, but also sanitizes the soil, which is especially important, for example, for potatoes that are prone to various diseases, whose development dolomite can suppress. In addition, it is important for potatoes that the fertilizer fights pests. As for feeding closed-type crops, the introduction of the mineral in the greenhouse will prevent the spread of fungi.

In autumn, it is recommended to fertilize the soil under fruit bushes and trees. Here, under each tree, you need to apply about 2 kg of fertilizer (along the edge, with a slight deepening), and for shrubs - from 0.5 kg to 1 kg (it all depends on the size) according to a similar scheme.

1. Do not mix dolomite with superphosphate, urea or ammonium nitrate, otherwise a dangerous reaction may start.
2. Clay soil should be fertilized annually.
3. You cannot fertilize gooseberries or sorrel with flour.

   

4. Fertilizer should be distributed as evenly as possible, thoroughly mixing with the soil and plowing about 15 cm (with the exception of shrubs and trees).
5. In spring, vegetables can be periodically watered with dolomite "milk" (a mineral diluted with water).
6. Manure is also good for the soil, but it shouldn't be mixed with flour. First, you need to scatter fertilizer, then - manure, and only after that the site can be dug up.

   

7. Turnip and cabbage yields will improve if flour is added directly at the time of planting.
8. Plums with cherries need to be fertilized every year after harvesting (the dosage is described above). So the fruits will be large and juicy.

   

9. When growing black currants, flour should be scattered every two years (0.5-1 kg under a bush, depending on size).

   

As a result, we note that dolomite flour acts gradually, so you should not expect an immediate positive effect. The greatest benefit observed two to three years after fertilization - the yield increases by 10-15%.

It is made by grinding dolomite stone. This mineral is very common on the territory of our country. The volume of its production today is quite enough to fully meet the needs of the state. This product is used in many areas of the national economy - in construction, animal husbandry, road construction, in the glass and paint and varnish industries. He found the widest application in agriculture. How to properly use dolomite flour for summer cottage, and we'll talk further.

Using dolomite flour to neutralize soils

This means is used primarily to improve acidified soils. The fact that on such a land it is impossible to get a good harvest from almost any crop is probably known to all summer residents. The fact is that the roots of plants in acidic soil very poorly absorb nutrients. Even the application of fertilizers and the increase in the "fat content" of the land does not change the state of affairs. One of the most effective means used to neutralize acidic soils is dolomite flour. The use of this agent for digging in the fall is an excellent way to increase crop yields by next year... Limestone flour is introduced in certain doses, depending on the degree of acidification of the site.

What other useful qualities does flour have?

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 extraordinary beneficial influence on the root system of plants, increasing the efficiency of its work. Garden and horticultural crops begin to assimilate different forms of substances such as nitrogen, phosphorus, molybdenum, and potassium faster and easier. Also, dolomite flour 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 crop deterioration due to damage to crops by certain types of insects is also one of the beneficial qualities of fertilizers such as dolomite flour. The use of this substance in the fall will lead to the destruction of the chitinous cover of beetles and worms wintering in the ground. In particular, this white dust strongly affects the hard integument of insects in the places of their articulation.

Another interesting property dolomite flour is that it is able to bind radionuclides. Therefore, after applying it to the soil, you can get a much more environmentally friendly harvest of garden and vegetable garden crops. It will be stored much better.

How much dolomite flour should be added

In the event that the soil has an acidic reaction throughout the entire area of ​​the site, in the fall it is worth filling it with dolomite flour completely. At the same time, it is important to correctly calculate the required amount. The dosage depends largely on the composition of the soil. So,

If the soil in the area 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%). Distribute flour throughout the garden as evenly as possible. Leveling is done with a rake. Then the soil is dug onto the bayonet of the shovel. Re-processing of the site will need to be carried out after about 8 years.

The timing of the introduction of limestone flour

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 expedient. You can add 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 introduced into 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 the harvest of this particular crop. Of course, it is important to observe the correct dosage. For example, flour is usually applied to the trunks of currants in an amount of 500 g per one bush. For cherries and plums, it is also used in the fall in the amount of 1-2 kg for one plant. If necessary, you can use this tool twice a year - both in the spring and in the fall.

Which plants respond best to limestone flour

Next, let's figure out what kind of plants limestone flour should be applied to. 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 soil improvement works most effectively on cabbage. Also, this tool is often used to increase the yield of tomatoes, eggplants, peppers and potatoes. It is worth adding flour for legumes, salads, barley and cucumbers.

In autumn, dolomite flour should be poured under everything.It can be garlic, winter onion, decorative garden plants etc. According to the results of research carried out by scientists, the use of lime flour can increase yields by 4-12%. The most noticeable effect from its use appears in about a year or two after application to the soil.

Of course, there are plants that don't respond well to a substance like dolomite flour. The use of this remedy in the fall or at any other time of the year under gooseberries or sorrel is not recommended. Do not use it under cultivated plants and in the event that the soil on the site has a neutral or alkaline reaction.

Dolomite flour compatibility with other fertilizers

It is also necessary to combine dolomite flour with other fertilizers correctly. In order to enhance the effect produced by it, 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 go well with manure either. Since the latter is used very often for plant fertilization, it is still used simultaneously with dolomite flour. However, you should follow one important recommendation. In the fall, dolomite is scattered over the garden bed and only then manure. Then they dig everything up.

What dolomite flour should be used in the fall

As already mentioned, limestone flour is most often 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 subdivided into classes and groups. In agriculture, rather fine (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 from it by plants.

Which conclusion follows from all this?

As you can see, limestone flour is a useful fertilizer and does not have any negative side effects on plants. Of course, only on condition correct use... The effectiveness of using dolomite flour is in direct proportion to the correct dosage. Before applying this fertilizer, it is imperative to conduct research on the level of acidity of the soil. Above pH 6 is unnecessary. You should not use flour in combination with incompatible fertilizers.

Dolomite flour is a fertilizer in the form of a powder, which is produced from the mineral dolomite, belonging to the carbonate class (formula - CaCO3 MgCO3), by grinding it to the smallest fractions. The introduction of this fertilizer into the soil not only normalizes its acidity, but also improves the structure of the upper fertile horizon, simultaneously enriching it with useful microelements such as magnesium and potassium. Also, dolomite flour helps to reduce the number of weeds on the site, and to activate the activity of beneficial microorganisms and small-bristled (annelid) worms. Another plus is availability, since its price is low, and you can buy this mineral fertilizer of natural origin in containers of any volume, based on personal needs.

Since this mineral dressing is of natural origin, it is not additionally saturated with various additives, and is used in its pure form. This allows us to attribute it to a high ecological class of use, and to conclude that the use of dolomite flour does not harm human health. Calcium and magnesium are in its composition in a carbonate form, which prevents their deposition and accumulation in finished fruit and vegetable products in too large quantities.

Properties

As mentioned above, dolomite flour, the composition of which includes calcium and magnesium, significantly affects the composition of the soil, changing its acidity.

But, in addition to the ability to deoxidize the soil - that is, to bring its composition to the values ​​most suitable for growth different plants, dolomite flour has a number of other advantages. She:

• Improves soil structure;
• Promotes the development of colonies of microorganisms in it, which have a healing effect on the soil;
• If dolomite flour is constantly applied, then it saturates the upper layer of the earth with easily assimilable nitrogen, phosphorus and potassium;
• Increases the return on the applied mineral fertilizers;
• Increases the content of calcium and magnesium in the soil;
• Helps plants to cleanse themselves of radionuclides;
• Destroys insects by dissolving their chitinous cover. Dolomite is completely safe for all other living things.

Determination of soil acidity

In order not to be mistaken with the amount of dolomite flour introduced, before applying fertilizer, it is necessary to determine the acidity of the soil. This can be done in many ways, here are the most affordable and popular ones:

Weed plants

Weeds, as well as cultivated plants, will not grow on soil that is not suitable for their acidity. Therefore, they are a kind of indicator indicating the pH factor. potting soil Location on. For example, dandelions, wheatgrass, chamomile, clover and coltsfoot grow on slightly acidic soils. On acidic ones - woodlice, plantain, buttercup, and on neutral ones - quinoa and nettle.

Vinegar

Using this table sauce is one of the easiest and quick ways to establish the norms for the introduction of dolomite flour. It is used this way - a handful of soil is poured with a few drops of vinegar and the reaction is monitored. If the earth begins to swell and bubble, then its pH reaction is neutral or acidic.

Grape juice

This natural ingredient is used as follows: a handful of earth is placed in a container with juice, and if the juice changes color and bubbles appear on the surface of the liquid, the soil has a neutral reaction.

Special devices

Of enough a large number specialized devices, which are produced by both foreign and domestic manufacturers, the following models of digital and analog portable pH meters can be recommended for private use. These are non-volatile EPA-102 and EPA-103, manufactured in Brazil, and HI-9025 and HI-9024, digital portable devices, made in Germany, providing high measurement accuracy. You can also use plain litmus paper.

Video: determination of soil acidity using litmus paper

Dolomite or lime - what to choose?

To deoxidize the soil, in addition to dolomite flour, slaked lime (Ca (OH)) is often used, which is popularly called "fluff". It is more commonly found on the market and is cheaper than dolomite powder. But does it surpass him in consumer properties?

Limestone flour is considered to be the most powerful agent for normalizing soil acidity. Calcium is included in its composition in the form of hydroxide (unlike dolomite, in which Ca is included in the form of carbonate), which enhances its effect on the acidity of the soil, increasing its ability to neutralize one and a half times.

Lime "works" faster and more active, but this property also has negative aspects. For example, in the first time after application, it interferes with the assimilation of the most essential substances for plants, such as phosphorus and nitrogen. Therefore, immediately after its introduction, nothing can be planted, the land must "rest". Therefore, lime flour is usually applied in the off-season, when the beds are prepared for winter, or in early spring to provide a good clearance before planting seeds and seedlings.

Unlike lime, dolomite can be applied at any time, as soon as the need arises. Therefore, it has become one of the most popular fertilizers that normalize the acidic environment of the soil.

Dolomite flour application

Dolomite flour is always used only after the acidity of the soil has been accurately determined, otherwise it can cause significant harm to plants, up to their complete destruction. General instructions for the use of dolomite flour are as follows:

• If the pH of the soil is less than 4.5, it is considered acidic. In such soil, 50 kg of dolomite flour are introduced per 1 hundred square meters.
• At a pH of 4.5-5.2, the soil is considered to be moderately acidic, and the rate of application of this mineral fertilizer- about 45 kg per 1 hundred square meters.
• Weakly acidic soils, with a pH reaction of 5.2 to 5.7 units, are fertilized with dolomite powder at the rate of 35-40 kg per hundred square meters.

Also, the amount of fertilizer applied depends on the structure of the soil. On light soils, the use of dolomite flour is reduced by 1.5 times, and on heavy, loamy and alumina soils, on the contrary, it is increased by 10-15% to normalize their structure.

When you are going to buy dolomite flour for fertilizing your beds, garden or lawn, all these nuances must be taken into account when calculating. It can be purchased both in the store and ordered on the Internet. This fertilizer has different packaging, it is sold in bags, bags and in bulk. To fertilize all the land in a summer cottage with an area of ​​six acres, 300 kg will be enough. Given that the price of one bag weighing 50 kg, according to the prices of leading suppliers for the spring of 2015, does not exceed 200 rubles, then you can completely fertilize the entire site for 1200 rubles. Given that dolomite flour is added no more often than once every three to four years, the price of the issue is more than acceptable, because all this time the soil will bring good harvests, and will not turn sour.

Dolomite flour is also added to compost, both in simple and in its biologically active form - vermicompost. Worms launched into untreated humus cannot live in compost with an inappropriate pH reaction, therefore, for their comfortable existence, which causes their active reproduction, which in turn accelerates the processing of organic matter, ground dolomite must be added to the pile. It will provide the required level of acidity.

When to deposit?

As stated above, dolomite fertilizers can be used at any time of the year, since they do not have a negative impact on the assimilation of others nutrients from the composition of the soil. But, usually they are applied before using other fertilizers, since dolomite flour can not organically interact with all of them.

On a plot intended for growing vegetables, in the spring it is scattered in advance, a couple of weeks before planting. It not only fertilizes and improves the structure of the soil, but also sanitizes it. This is very true for various cultures, including for, which is often affected by various diseases, whose occurrence and distribution dolomite is able to suppress. It is also especially important for potatoes that this mineral destroys insects by dissolving their chitinous shells at the joints. This helps to fight the bear, Colorado potato beetle and other potato pests.

Dolomite flour, the use of which has a sanitizing effect on the soil, is especially relevant in spring, as a mineral supplement for plants in greenhouses. When processing the soil with this mineral in the greenhouse, various fungal diseases do not spread, which has a positive effect on the harvest, and on the subsequent safety of the fruits and berries obtained.

In autumn, this mineral dressing is used to process and feed fruit trees and shrubs. In this case, the following rates of application into the soil are recommended - under a tree - about 2 kg, along the edge of the near-trunk circle, deepening into the ground, for shrubs (depending on size) - 0.5-1 kg according to the same scheme.

Liming is a term that is often used to describe the fertilization of the soil with rocks that contain calcium. This is not always true, since different substances have different effects on plants. Therefore, before starting to improve the soil by normalizing its pH-factor, it is necessary to carefully study the instructions for using the fertilizer intended for this purpose, since an excess of Ca and all its compounds is much more harmful than its deficiency.
