Depending on the varietal group, the age of the seedlings suitable for planting in open ground, is: for early tomatoes - 45-50 days, average ripening - 55-60 and late terms - at least 70 days. When planting tomato seedlings in more young age the period of its adaptation to new conditions is significantly lengthened. But success in obtaining a high-quality crop of tomatoes also depends on the careful implementation of the basic rules for planting seedlings in open ground.

Unpretentious plants Sansevierias of the "second plan" do not seem boring to those who appreciate minimalism. They are better than other indoor decorative leafy stars for collections that require minimal maintenance.

At the same time, it is able and very diversified the picture in the garden, moreover, from spring to autumn.

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. That on such a land it is impossible to get good harvest almost no culture is known, probably, to all summer residents. The fact is that the roots of plants in acidic soil absorb very poorly 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 tool for digging in the fall is an excellent way to increase crop yields for the 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 unusually beneficial effect on the root system of plants, increasing the efficiency of its work. Horticultural and horticultural crops begin to be absorbed faster and easier different shapes substances such as nitrogen, phosphorus, molybdenum, potassium. 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 yield decline due to crop spoilage by certain insect species is also one of the useful qualities fertilizer 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 adding it to the soil, you can get a much more environmentally friendly net harvest garden and 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 trunk circles 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 sprinkled 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%. 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 product 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 its 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, one should observe 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 made. Depending on these two factors, lime flour is divided into classes and groups. In agriculture, rather fine (with particles up to 1 mm) dolomite flour is usually used. The burnt version can also be used as fertilizer. 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 side effects on plants. negative impacts... Of course, only on condition correct use... The efficiency of using dolomite flour is in direct proportion to 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 is a carbonate rock, which is a complex of calcium and magnesium, and the so-called "dolomite flour" is crushed dolomite. This mineral is widely used in plant growing. Knowing what dolomite flour is, how to use this product in the garden and in what ways to apply it, you can significantly improve the condition of the soil and increase the productivity of plants.

Most of the Russian garden plots are located on acidic podzolic soils. Among garden crops, it is difficult to find acidophilic plants that prefer to grow on such soils.

The acidic reaction of the environment negatively affects the development of plants:

  • nitrogen is poorly absorbed, plants show symptoms of nitrogen starvation: chlorosis, growth retardation, crushing of leaves and fruits, kidney death;
  • phosphorus passes into an indigestible form, the plants show symptoms of phosphorus starvation: general depression, leaf death, deterioration or cessation of flowering and fruiting;
  • useful soil flora is suppressed, the activity of pathogens increases, plants are strongly affected by root rot and fungal infections.

At high level the acidity of the soil (pH less than 5.5 units), it becomes mandatory to use a deoxidizer, which is dolomite flour. When transferred to a soil solution, calcium and magnesium carbonates neutralize acids and make the soil more suitable for crop production.

Speaking about why dolomite flour is needed in the garden, it is worth noting the important role of calcium in fertility. Analysis different types soil shows that the less of this element the soil contains, the lower the fertility:

This dependence is explained by the fact that calcium ions help the formation of soil colloids, due to which the porosity increases and the structure of the soil improves.

For which plants is it useful?

Almost all garden crops will respond well to the introduction of dolomite flour.

Its use is especially useful when growing the following plants:

  • all types of cabbage;
  • radish, turnip, daikon;
  • beets and chard;
  • green crops: dill, parsley, celery, cilantro, salads, mustard;
  • onion crops: onions, leeks, slugs, batun, shallots, chives, garlic;
  • carrot;
  • potatoes and eggplants;
  • pepper;
  • garden strawberries;
  • pumpkin crops: cucumbers, zucchini, pumpkins, squash;
  • melons and gourds: watermelons and melons;
  • legumes: peas, beans, beans.

More tolerant of increased level pH of tomatoes, but the addition of dolomite flour will also have a beneficial effect on their yield. Under acidophilic fruit and decorative crops(blueberries, sorrel, cranberries, gooseberries, rhododendrons) the soil does not deoxidize.

How to use it correctly?

Before using dolomite flour, it is necessary to determine the acidity and granulometric composition of the soil. The application rates directly depend on this:

soil pHGradingDolomite flour application rate per 1 m2
5,0-5,5 Medium to light loam300 grams
350 grams
Sandy loam or sandy soil250 grams
4,5-5,0 Medium to light loam400 grams
Heavy loam, clay, peaty or silty soil450 grams
Sandy loam or sandy soil350 grams
Below 4.5Medium to light loam500 grams
Heavy loam, clay, peaty or silty soil550 grams
Sandy loam or sandy soil450 grams

If the pH of the soil is from 6.0 and above, it is not recommended to use dolomite flour.

Dolomite flour addition

Dolomite flour can be added to the soil in four ways:

  • Over the entire area of ​​the site. Based on the application rates, flour is scattered over the surface of the site, after which the soil is dug up.
  • In the garden or near the trunk circle. Based on the application rates, the flour is distributed over the prepared bed and embedded in the soil with a rake. Embedding in trunk circle is made with a flat cutter, after which the soil is mulched.
  • Into the landing hole. When planting seedlings or when planting potatoes, 5 tablespoons of dolomite powder are poured into each hole, mixed with the soil and planted.

To increase the efficiency of dolomite flour, it is useful to apply it simultaneously with well-ripened compost, manure or leaf humus. It cannot be used simultaneously with mineral fertilizers. If this type of dressing is preferred, the deoxidizer and fertilizers are applied at intervals of at least 1 week.

Fertilizer application terms

Most often, dolomite flour is used in autumn or spring preparation soil. In autumn, this is done after harvest, in spring - 2-3 weeks before sowing.

Dolomite powder can be used in summer time... During this period, it is more convenient to process perennial crops by embedding the product in the trunk circles.

The frequency of treatments depends on the properties of the soil. On heavy clays, dolomite flour is used every year. On medium and light soils - once every 3-5 years.

The effect of feeding

The effect of adding dolomite flour does not appear immediately. The shift in acidity occurs in a few months, so it is more profitable to cultivate the soil in the fall on highly acidified soils. Spring and summer applications are carried out on well-cultivated soils in order to maintain an optimal acid-base balance.

The systematic and competent use of dolomite flour in the garden leads to the following results:

  • a noticeable improvement in the physicochemical characteristics of the soil;
  • increasing the activity of beneficial soil flora;
  • reducing the incidence of fungal and bacterial infections in plants;
  • reduction of plant infestation by soil pests;
  • an increase in the power of the root system of plants, the formation of healthy, even root crops and tubers;
  • general increase in crop yields.

The maximum effect develops in 2-3 years after the introduction of dolomite powder and the transition of calcium and magnesium into the soil solution.

How to replace dolomite flour?

In addition to dolomite flour, the following means are used to deoxidize the soil:

MeansCharacteristicMethod of application
Fluff limeRepresents slaked lime - Ca (OH) 2. Has a more active neutralizing effect than calcium carbonate. Requires a longer interval between tillage and planting.Deep incorporation into the soil when digging in autumn time, after harvest. It is used no more than 1 time in 6 years.
Wood ashDeoxidizing properties are milder than dolomite flour. Suitable for slightly acidic soils with a pH of at least 5.5. It is valuable as a potassium-phosphorus fertilizer with a large additional set of elements - calcium, zinc, sulfur, etc.Shovel filling in spring or autumn processing soil. Nesting in the holes when planting seedlings or planting potatoes. Summer watering with water solutions.
AgromelPartial analogue of dolomite flour, pure calcium carbonate, no magnesium carbonate. In terms of deoxidizing effect, it is equivalent to dolomite powder.In spring or autumn, it is sealed under a shovel once every 6 years. It is introduced into planting holes or beds, like dolomite flour. It dissolves well in water and is used for summer irrigation.

Thus, dolomite flour on strongly acidic soils can be replaced with either fluff lime or agromel. In areas with a slightly acidic soil reaction, it is more profitable to use wood ash.

Pros and cons of using

Like any other product, dolomite flour has its advantages and disadvantages:

Considering the fact that dolomite flour has noticeably more advantages than disadvantages, it can be considered an almost ideal tool for improving the soil. When dolomite powder is applied in accordance with the application rates, there are no negative side effects not visible.

For normal growth and maturation of various crops, fertilizers are used. It is not uncommon to hear from experts and agro amateurs with experience about dolomite flour as a lime fertilizer. What is dolomite flour, its composition, how it is used and for which crops it is suitable, we will tell our readers.

Dolomite lime - plant reaction and dosage

Lime fertilizer made from dolomite flour is an ideal groundbait for crops such as beets, carrots, onions. buckwheat, alfalfa, potatoes, flax, clover, etc.

Dolomite flour consists of a fine powder of light gray, brown or white... Groundbait composition: limestone + boric acid. Compound boric acid at different manufacturers can vary from 5 to 10 g per 1 kg of limestone. Since it contains boric acid, dolomite flour is often used for disinfection and protection of plants from insect pests. The limestone included in the composition is an excellent bait for various crops. They began to use it more than 50 years ago, first in large agricultural land, then on any private plot. Fertilizer is inexpensive, but brings a lot of benefits.

Dolomite flour is introduced into any kind of soil on open beds or in greenhouses. it is especially effective for sandy or sandy loam soil. Since the soil is enriched with magnesium during use. It makes no sense to apply on neutral ground.

Pros of using lime fertilizer

It is necessary to add dolomite flour every 3-4 years, since the effect is long-term. After using dolomite flour, the soil acquires a number of positive qualities:


The benefits of dolomite lime are undeniable. But for correct processing fertilizer must be applied correctly.

Dolomite lime application rates

It is necessary to apply lime fertilizer in accordance with the type of soil. In this case, it is necessary to take into account the acidity of the earth. Read more about the rates of lime application depending on the type of soil in the table:

It is important when making to take into account not only acidity, but also the lightness of the soil. So if the earth is light, then the dosage must be reduced by 1.5 times, for heavy clay add 10-15% of general norm... In order for the effect to be the same, you must try to cultivate the land evenly. If you add the required proportions of ash, the effectiveness can last up to 5 years, and on dense soil up to 8 years.

To obtain greater efficiency, together with dolomite flour, they are introduced into the soil copper sulfate and boric acid. Microfertilizers will enhance the effect of dolomite.

More details on the introduction of bait can be seen in the video:


Reaction of various crops to dolomite soil fertilization

All crops under which dolomite flour is applied, according to their reaction to fertilizers, are conventionally divided into several groups:

  1. Plants for which growth in an acidic environment is unacceptable: all types of beets, cabbage, sainfoin, alfalfa. Plants love soil with a pH of 7 to 7.5, so the responsiveness to the use of lime is active, even when growing on slightly acidic soil.
  2. Plants that can grow on acidic soil, but are sensitive to it: winter and spring wheat, barley, soybeans, corn, cucumbers, onions, clover and broad beans, lettuce. Development goes well on soil close to acidic pH from 6 to 7. Lime is responsive to use on acidic, slightly acidic and neutral soil.
  3. Plants that react poorly to acidic soil: oats, buckwheat, carrots, radishes, tomatoes, rye. They grow well on soil acidity, pH 4.5 to 7.5. They react well to ash on slightly acidic soil with acidity of pH from 5.5 to 6. After application, it is recommended to use nitrogenous fertilizers.
  4. Plants that need to be limed only when growing on medium to strongly acidic soil: flax, potatoes. So if you do not lime potatoes, then it becomes covered with scab, starch in the culture decreases.

Before applying fertilizer, you need to analyze the soil in your area:

  1. For strongly acidic soil, more lime should be used.
  2. The absorption properties of the earth. For clay and loam, it is necessary large quantity than for sand.
  3. The amount of precipitation in the region. Melted water and rainwater quickly wash out calcium from the fertile layer.

Features of the introduction of dolomite lime

It is important during liming to evenly apply fertilizer to the soil and embed it in the top layer. To do this, after application, the soil of the upper layer is stirred by 15-20 cm. If you do not cover, the result will not come earlier than in a year. Dolomite can be added together with manure for greater efficiency and acidity reduction, but they cannot be mixed. lime flour is introduced first, then manure and dig up everything. Application: Dolomite - 200-500 g / m 2, manure - 4-5 kg ​​/ m 2.

Dolomite flour does not damage or burn the stem and leaves of crops, therefore it can be used on lawns and in places of grazing. Fertilizer can be applied in any season, but it is easier to do this in the fall after harvest. To be applied every few years, but on acidic soil it is better every year.

The rates and methods of application for various crops are shown in the table:

Do not add dolomite lime for crops: cranberries, gooseberries, blueberries, sorrel.

As we already said, it is good to use lime dressing with nitrogenous and mineral fertilizers, but there are exceptions, the use with which mixing is unacceptable: urea, ammonium nitrate, ammonium sulfate, granular superphosphate, double superphosphate.

The benefits of using lime fertilizing will be noticeable through different period time. Depends on factors:

  1. The acidity of the earth.
  2. The size of the applied lime fertilizers and their type.

The higher the acidity of the soil, the greater the rate of flour per 1 m 2 of soil. Since they disperse slowly in the soil, the maximum effect occurs in 1-2 years.

Mineral and organic groundbaits become more effective after adding lime flour, so they can be applied after processing half the usual rate. A greater effect appears after treatment with the introduction of acidic ammonia and potassium compounds.

Lime flour treatment according to Meathlider

According to the Mitlider method, it is necessary to add lime flour with a mixture: limestone or dolomite flour 1 kg + 7-8 g of boric acid. It is necessary to introduce before digging for each crop separately or when changing from one type to another. Together with the dolomite mixture, it is proposed to add mineral fertilizers... If the soil is clayey and heavy, peat bogs and swampy areas, then the application rates for a bed up to 1 m wide by 200 g per 1 m p., On light soil by 100 g. If the soil is saline or alkaline, then you can use simple gypsum for the same norms.

Many greenhouses and agricultural complexes work according to the Meatlider method. In private households, they began to use it relatively recently. Effectiveness occurs within 1-2 years after application.

How to buy lime flour correctly

Before buying a composition, you need to look at the shelf life of dolomite flour. the fact is that when correct storage the term is 2 years. But it is necessary to store the bait in a dry room with a temperature not lower than +5 0 С. Unscrupulous sellers keep products in winter in unheated warehouses, where it loses a number of its qualities. It is difficult to determine by eye before buying, so it is better to take products of a fresh year of production.

Dolomite flour is sold at large and small specialized stores, on the agro market or via the Internet. It is better to purchase in specialized centers. after asking the seller for a copy of the quality certificate for the goods.

You can buy dolomite flour from the manufacturer, but the batch size must be at least 1 ton. The price for it will be lower. Sold dolomite flour in packaged cellophane or paper bags weighing 1, 5, 10, 15 kg. 50-100 g and roll in bags. The price for the convenience of readers is presented in the table:

Packing size price, rub.
50 g From 20
100 g From 35
1 kg From 340
5 Kg From 1600

Dolomite lime in bulk in bags is cheaper (price from 135 rubles / kg), but it is more difficult for the seller to store it, and it is impossible for the buyer to determine the shelf life. It is safer to buy in the original packaging in packages of 1 and 5 kg.

To begin with, let us explain that dolomite is a mineral from the carbonate class with a crystalline structure. It has a glassy luster, and the color can be very varied - grayish, white, slightly reddish and even brownish. Dolomite flour is obtained by grinding minerals to a powdery state and further drying. All this is done in a production environment. Dolomite flour contains 8% more calcium than lime. And another important difference from lime is the presence of about 40% magnesium in dolomite flour. If there is little magnesium, then the plants stop in development and growth, and brown spot and chlorosis. The price of this fertilizer is relatively low, and a lot of useful properties are found, which contributed to its popularity among gardeners.

The benefits of dolomite flour

Dolomite flour can be introduced not only into open ground in the beds, but also into greenhouses and hotbeds. And flower growers use it widely. Its use is especially good for sandy and sandy soils, poor in such an element as magnesium. What can you expect if you periodically add it to the ground?

  1. Biological, physicochemical and physical properties soil. The increased acidity of the soil is neutralized.
  2. There is a significant increase in the amount of good available to plants forms of phosphorus, potassium, nitrogen, molybdenum.
  3. There is an increase in the efficiency of those fertilizers that summer residents make, especially manure.
  4. The soil is enriched with calcium, while improving root system plants.
  5. The soil is saturated with magnesium, which is a constituent of chlorophyll and actively participates in photosynthesis.
  6. Plants eat better, change in better side conditions of their maintenance.
  7. The harvest becomes of a higher quality, more environmentally friendly (radionuclides are neutralized), it is better and longer preserved in winter.
  8. It can be used as a means of fighting insect pests, because well-ground dolomite destroys the chitinous covers of insects dangerous to plants.

How to use it correctly?

The amount of dolomite flour that needs to be applied to a garden bed depends on the acidity of the soil at a given location and the mechanical composition of the soil mass. MirSovetov will name only average rates:

  • acidic soils (reaction of the environment less than 4.5) - on square meter the area is applied from 500 to 600 grams;
  • medium acid (reaction of the medium in the range from 4.5 to 5.2) - per square meter is from 450 to 500 grams;
  • slightly acidic (the reaction of the medium is from 5.2 to 5.6) - from 350 to 450 grams are taken per square meter.

If the soil is clayey, heavy, then the amount of this fertilizer is increased by 10-15%. For light soils, the dosage can be reduced by 50%.

You can check the soil and find out the acidity indicators by purchasing from a garden store or center special devices or tests.

The efficiency of use increases if copper sulfate and boric acid are added at the same time.

Crops are classified into the following main groups depending on how they relate to the reaction of the environment in which they grow and liming:

  1. Not tolerant of acidic soils - cabbage, beets, alfalfa. They need a soil with a neutral or slightly alkaline reaction. They love to be fed with dolomite flour.
  2. Sensitive to living in an environment with high acidity - cucumber, lettuce, beans, onions, peas, corn, wheat, soy. For them, the preferable soil, the reaction of the environment is close to neutral, respond well enough to the use of dolomite flour.
  3. Weakly sensitive to an increase in soil acidity - tomatoes, carrots, radishes, oats, buckwheat. They grow quite normally with any reaction of the medium of the soil mixture, but the best results are shown on slightly acidic soils. If the soil is highly or moderately acidic, then dolomite flour can be added to the soil in full dosage. Then the plants will better feed on nitrogen and ash compounds.
  4. Requiring liming only for strongly acidic and medium acidic soils. For example, flax likes to grow in slightly acidic soils. Slight acidity will not affect the yield of potatoes planted in this area.

Features of the introduction

On heavy clay lands, dolomite flour will have to be applied every year, on the rest - once every three years.

It is more convenient to do liming in autumn. But if necessary, dolomite is added in the spring or at any time.

When liming dolomite flour, spread evenly over the entire soil surface to a depth of 15 cm, stirring thoroughly. If you just sprinkle dolomite on the surface, then the effect will be, but you will notice it not earlier than after 12 months.

Dolomite and manure can be added to the soil at the same time, but they cannot be mixed together. First, dolomite flour is scattered, then manure is spread, the third stage is digging.

Leaves will not be affected if you scatter this flour over your lawn, pasture.

Under cherries, plums, add one or two kilograms of dolomite flour every year after you harvest.

Once every two years, apply under each bush black currant about 500 grams of dolomite. If the bush is large, then you can add a kilogram.

Under cabbage, turnips, add dolomite when planting plants.

In the spring you can water plants, for example, beets, clematis, with dolomite "milk" - water to which dolomite flour is added.

Do not apply this fertilizer under sorrel, gooseberries.

Dolomite flour is added under the flowers before planting - in a pot or hole, be sure to mix well with the rest of the soil mixture. Hyacinths, orchids, violets respond positively to the introduction of dolomite flour.

Do not mix dolomite flour with urea, superphosphate, ammonium sulfate, ammonium nitrate.

If it turns out that the soil on your site has a neutral reaction of the environment, then liming is not necessary.

Positive results will not be noticeable immediately, and the greatest effect appears somewhere in the second or even third year after liming. Scientists believe that dolomite flour can increase the yield by an average of 4-12%.
