In the interaction of phosphate raw materials and wetting solution reaction occurs rapidly, requires intensive mixing, the temperature of the unheated rises to 33°C. For the further transfer of the components of phosphorite in an accessible, digestible form salts, macro - and micronutrients should the temperature be increased to 95-120°with a ratio of T:W=1:(7...10). This provides a fluid form of pulp, as well as the increased yield of digestible phosphorus.

With increasing duration of interaction between the phases, the content of free acid in the liquid phase decreases. pH homogeneous pasty mass does not exceed about 7.6 to 8.2.

Thus in the mass formed harmless soluble salts suitable for recovery of the soil and change its structure.

The introduction of the improver of bischofite brine gives it insectofungicide properties.

The resulting slurry of bischofite and phosphate are mixed to a homogeneous mass of slag metallurgical production with etching solutions and phosphate with the etching solution in the ratio of phase 1:1:1 for 1 hour at a temperature of 45-70°to obtain a pasty mixture.

Pasty mixture ensures that useful salts formed in the neutralization process slag and sludge, are in a soluble form. Drying and burnout to obtain dry solids or granules last again leads them into insoluble oxides. For drying and granulation requires 8-12 times more energy than receiving improver in the form of a water-soluble paste.

Steam at a temperature of 95-125°filed shirt cyclone chamber 8 under the handles of sustainable chemical reactions and homogeneous mixture for permanent issuance by the dosing pump 14 from the cavity of the chamber 8.

Flow divider 35 flow part of the ground phosphate rock in the cyclone chamber 9 and the liquid component of the brine natural mineral bischofite formula MgCl2·6N2O - from the tank 33 in the ratio of phases T:W=1:4, and the mixing screw mixer 13 at a temperature of 80-90°C for 1-2 hours allows, firstly, parafinoterapija materials to produce in soluble form, and secondly, the minerals from the brine evenly placed on macrostructure phosphate.

Next dosing pumps 14 cyclone chambers 7, 8 and 9 of the mixture in equal mass proportions (1:1:1) served in the cavity cyclone chamber 10 and is subjected to intensive mixing for 1 hour at a temperature of 45-70°to obtain a pasty mixture with an average humidity of 28-32%.

Vane pump 36 pasty mass improver of the cyclone chamber 10 is unloaded into containers or other container with a large volume, suitable for transportation on the highways and on track.

The processing described waste production and the presence of a large amount of the natural resource base with efficient production allows you to extend the functionality improver, as it contains all the basic nutrients NPK and trace elements in a wide range of their presence and a higher concentration than in the known micronutrients in scoprio the new production. Extended resource base eliminates landfill waste. This is an important factor in protecting the environment. The exception to technological cycle of operations of drying and granulation significantly reduces energy and labor costs of additional heating, mixing and transport.

All items improver in the form of sulphates, chlorides, nitrates and oxides in motociclete and limoniastrum forms.

With the proposed ameliorant in alkaline soil of phosphate and brine mineral bischofite come microelements, necessary for the growth and development of plants. The nutrient content in the received improver presented in table 8. For comparison, table 9 presents claravia the values of the elements in the soil.

Described improver was tested in the period 1999-2004 on salts, alkaline complexes and agrogenic sodic soils in the Volgograd region in wheat and collective farms, as in the southern and in the Northern zone.

Table 10 presents data productivity of spring barley varieties Donetsk 8 according to research in 2003 and 2004 in farms Kotelnikova district of the Volgograd region on the old cultivated sodic soils. Improver introduced in 2002 after the dress and the predecessor jagersbacher the rate of 3 t/ha Next, the field was subjected to disking and moldboard plowing to a depth of 0.25 to 0.27 m

Table 11 shows the structural response analysis improver on the development of the early-ripening barley Donetsk 8 and the value of the crop for grain.

Table 12 gives the results of the economic yield of spring barley varieties Donetsk 8 in Gorodishche district of Volgograd region.

Table 13 shows the economic yield of spring barley varieties Donetsk 8 when you make 3 tons improver in 2002 and its effects against diseases of cereal.

Efficiency made improver doses of 1 and 3 t/ha is also confirmed on the crops of spring and winter wheats released varieties (see data tables 14, 15 and 16).

Received improver has a prolonged action. Getting in the arable layer of the soil improver is further interaction with the soil aggregates and goes into a digestible form for plants and replacement with cations of Na+and Mg2+the soil solution.

The estimated dose of 3 t/ha is sufficient to rasoloniriana 50% alkaline complexes in the course of one year.

Described improver has a positive effect on the growth and development of plants grain formation and grain swelling and protection of plants from diseases.

Describes a method for improver on the basis of waste metal is formed production from phosphate rock and bischofite brine reduces the energy consumption to produce complex mineral fertilizers with microelements, get improver on the basis of mass-produced by industry processing equipment, actuators and devices, instrumentation conventional technological schemes, to use accumulated decades of metallurgical waste production, increase the degree of decomposition of the waste, to improve the quality and quantity of nutrients, garbarini functions and properties in improver, to reduce the time of the technological cycle and to ensure the continuity of the technological process of obtaining a paste-like material.

Presented in tables 9-16 data suggest prolonged action improver at 3 and 4 years after introduction and expansion of assortment of reclamation funds.

Described improver based on phosphate rock, salt and brine natural mineral bischofite and metallurgical wastes and electroplating can improve physical and physico-chemical properties of alkaline complexes. In addition, improver contains up to 13% of phosphorus, which is one of the most important elements of plant food, including cereal.
