Dolomitic flour: appointment, composition and application

Dolomitic flour – fertilizer in the form of a powder or granules, which is used in construction, in poultry farming and gardening in the cultivation of various plant crops. The main function of such an additive is to stabilize the acidity of the soil and the enrichment of the mineral substances of the upper land layers.

Properties and composition

Dolomite called mineral from carbonate class. His chemical composition:

  • Saa – 50%;
  • MGO – 40%.

Mineral also consists of iron and manganese, sometimes they find zinc, nickel and cobalt in small percentage. Dolomite is yellowish gray or has a light brown color. Less often occurs white mineral. Its density is 2.9 g / cm3, and the hardness is ranging from 3.5 to 4.

Back in antiquity, people noticed that plants growing on the rich dolomite lands were actively developed and fruited. Later, the mineral began to be mined and processed into flour intended for enrichment of soil with useful substances. Such an additive contains a large calcium percentage and magnesium. These minerals contribute to the active vegetation of plant crops and obtaining abundant yield.

Limestone dolomite flour make by grinding a mineral produced by nature. It does not need additional contribution to other fertile substances. Due to the moderate content of calcium and magnesium, these minerals do not accumulate in the soil. The additive is perfectly dissolved and evenly distributed over the top soil layers.

Properties of dolomite flour:

  • enrichment and improvement of chemical indicators of the soil;
  • creating optimal conditions for the development of useful microflora;
  • activation of the effectiveness of other mineral additives introduced into the soil;
  • improving plant growth;
  • Protection and release of plant crops from free radicals;
  • Developmental effect on harmful insects, damaging roots and foliage of garden crops (mineral contributes to the destruction of the chitinist protective layer of pests).

Dolomitic flour in the country or garden is needed for the deoxidation of the soil – stabilization of the acidic level of the soil.

Comparison with lime

Dolomitic flour and lime – two mineral fertilizers to enrich the soil. Both of these additives are applied with gardeners and gardens to deoxide the soil. However, there is a big difference between these fertilizers. Dolomitic flour differs from lime for calcium content. In the dolomite of this component contains 8% more than in the lime.

Additionally, there is a magnesium in the dolomite flour, which is not in lime. This substance contributes to the active growth of plants and the prevention of fungal diseases. Dolomite flour, unlike lime, speeds up the development of the root system of gardening crops. Its magnesium incomes to improve photosynthesis. The lime does not contain MG, and if not to make this component additionally, the plants will soon be covered, and their foliage will gradually fall.

However, harated lime has additional benefits. For example, it is about 1.5 times faster restores the acidic level of the soil, but at the same time the plants are more difficult to assimilate the high-speed fertilizer.

Purpose

Dolomitic flour has a positive effect on the structure of the soil. It is applied not only as a soil deoxidizer, it is also recommended to use for neutral-alkaline lands. Fertilizer helps to increase the level of calcium, hydrogen ions, promotes the reserves of the supply of nutrient components in the soil.

Dolomitic feeding is often used in the garden against moss on the lawn. Mineral additive is also used for fruit and vegetable crops, colors, coniferous plants and trees, “preferring” moderate, weakly acidic and alkaline types of soil. It is used for:

  • orchids, violets, hyacinths;
  • cherries;
  • apple trees;
  • pears;
  • carrots;
  • Bulgarian and acute peppers;
  • eggplants and other plants.

To increase the duration and abundance of flowering, it is recommended to pour under the strawberries and under raspberry in the late summer and early autumn. Feeding the best thing to make after harvesting.

Special attention is required when adding additives under tomatoes, potatoes and cucumbers. In this case, it is necessary to observe strict dosage standards of mineral feeding.

For potatoes

This garden culture prefers the weakly acidic soil with a pH level from 5.2 to 5.7. In order not to harm the plant, you should not produce severe tillage. Dosage dolomite flour:

  • For acidic soil, half aklogram of feeding for 1 m2 will be required;
  • For soil with medium acidity – no more than 0.4 kg per 1 m2;
  • For weakly acidic soils – no more than 0.3 kg per 1m2.

If there is severe earth on the summer ground, processing is recommended every year. For light soil, it is enough to make feeding 1 time in 3 years. Treatment of dolomite flour helps to increase the content of starch in the tubers and prevents potato disease in pairs. In addition, the Botomit scattered on tops is actively fighting with Colorado beetles and their larvae.

For cucumbers

In this case, 2 methods of making mineral additive are used – when planting seeds or during soil resistance for its deoxidation. During the sowing, a groove should be done in which the Dolomites flour mixed with the soil. Direct contact of seeds with Dolomite is unacceptable. During the spring resistance, the dolomite additive must be scattered on the site where the cucumbers are planned.

For tomatoes

Dolomite feeding for tomatoes is advisable only in soils. To stabilize the pH-level, flour with boric acid (100 and 40 grams, respectively) should be mixed. For sandy soil you need to take at least 100 grams of money per 1 m2, for clay – approximately 200 g.

Fertilizer is recommended before landing seedlings. Otherwise, the additive can “wash away” during rains in deep soil layers – in this case the composition will not have a useful impact on the development of the root system of tomatoes.

How to produce?

Dolomite flour is made from the corresponding mineral. His large deposits are located in the USA, Mexico, Italy and Switzerland.Dolomite is mined in Ukraine, Belarus and some Baltic countries. In Russia, the mineral deposit found in the Urals and in Buryatia. And he is found in Kazakhstan. Dolomite grinding is produced on specialized equipment – rotary crushers.

At the same time, fertilizer can be both fine-grained and crushed into powder. Additive Features in Waterproof Packages of Various Capacity.

Tempets trees

This is an important procedure for adults and young garden trees. Bring trees is recommended at least 2 times a year. The first processing is carried out in the fall (October-November), the second – spring (from the beginning to mid-March). Fruit trees need to break the barrel, ranging from the root cervix and to the skeletal branch located on the lower tier.

Teaches performs a protective function. It helps to significantly reduce the risks of obtaining bodies from the bright spring rays, protects from cracking with sharp temperature differences. In addition, lime compositions contribute to getting rid of trees from insects, which lay their larvae in the tree bark.

It is recommended to use non-pure lime flour to process the trunks, but a special solution. For its cooking you need to take:

  • 1 kg of chalk;
  • 1.5 kg of dolomite flour;
  • 10 liters of water;
  • 10 tablespoons of flour blasting (instead you can use soap or clay).

To prepare a working solution, you need to mix all the components before receiving a homogeneous mass (visually on the consistency, it should resemble sour cream). Do not use too liquid or thick. In the first case, it will drain from the trunks. The thick solution will fall onto the trunk with a thick layer, which will lead to its rapid exfoliance. The optimal thickness of the chicken layer is 2-3 mm, not more than.

Making to the Soil: Terms and Consumption Norms

Dolomite flour is needed in the soil according to the instructions. Supplement will be useful only if the soil has increased acidity. To determine the level of the pH, you need to use indicator lactium paper or special instrument. If there is neither one or the other, you can resort to folk methods.

To find out why the soil is screened or not, you need to scatter its samples on a flat surface and pour vinegar. The appearance of a rapid reaction will indicate an alkaline environment. In the absence of “hissing” or with a weak flow of a chemical reaction, it is possible to draw conclusions about the acidification of the soil.

Norms of emissions for the deoxidation of the upper fertile layers:

  • For soil with a pH from 3 to 4, it is necessary to take at least 55 kg (approximately 600 g of dry feeding for 1 kV.m);
  • For weakness soil with pH 4,4-5.3 – no more than 50 kg of dolomite flour;
  • For weakly acidic soils with pH 5-6, it is enough of 25-30 kg.

Decking dolomite flour is recommended to produce no more than 1 time in 5 years. And also there are certain rules for making a mineral supplement to the ground in the open plot and in the greenhouse.

In open primer

Dolomite powder is allowed to use as an additional feeding regardless of the time of year. In the summer of flour make “milk”, mixing the feeding with water in the ratio of 1:10, respectively. Such a solution is intended for watering plants. Processing frequency – 1 time in 5-6 weeks. Dolomite flour is recommended to be used in autumn for feeding fruit and berry crops. The lifting supplements are made after harvest – at the beginning, middle or late September. After that, the soil must be exploded.

For deoxidation, the dolomite flour is best to make spring under the steam. In this case, the additive must be evenly scattered over the entire area of ​​the site and to dissolve with rake. After that, you should switch the soil to the depth of the bayonet shovel.

In closed primer

Dolomitic flour is designed not only for use in open areas. It is also used in greenhouses, greenhouses, floral oranges. For closed soil, the dosage of additives should be reduced. In the greenhouses recommended for 1 m2 to take no more than 100 grams of powder. Since the earth is protected from precipitation and gusty winds, feeding can not be chopped into the ground, but leave on the surface. Due to the educated thin layer of moisture in greenhouses and greenhouses will evaporate slower.

Analogs

Many gardeners and gardeners are interested in how to replace the dolomite flour. The analogues include ash from the burned wood. It is necessary to take into account that for the deoxidation of the soil of ash will be needed 3 times more. Analogs also include haired lime. To eliminate the risks of burns in plants, limestones should be made only in the autumn period. This substance is characterized by speed.

After his introduction, plant cultures are poorly absorbed by phosphorus, so it is best to make a lime after harvesting into the ground under the pextop. Instead of dolomite powder, you can apply chalk. This substance is rich in calcium. Before making chalk, it is recommended to grind, then you need to sprinkle with the soil and explode it.

It is necessary to take into account that the chalk clogs the soil and helps to increase the level of salt in the soil.

Compatibility with other fertilizers

Dolomite flour combines with many types of feeding for gardening crops. Together with it is allowed to use Bordeaux liquid, iron vapor and compost. These components are able to neutralize the disadvantages of mineral additive. Active growth, vegetation and yield will be repaid by the plant to feed the dolomite flour in the complex with peat, cow or boric acid.

There are several types of fertilizers that cannot be used simultaneously with mineral flour. These include urea, superphosphate, ammonium sulfate. The introduction of these fertilizer components is allowed only after 2 weeks after feeding by a dolomite powder.

Precautionary measures

With a frequent payment of dolomite flour, it is possible to reduce yield volumes. Fingering plants need correctly without disrupting the instructions and dosage standards. For each culture, the desired amount of feeding should be made. If you do not consider these factors, then plants may get sick. When applying several fertile substances, you need to learn about their compatibility.

It should be remembered that the shelf life of dolomite flour is 2 years. The overdue composition is lost a number of unique properties, which is why it may be useless for plants.
