(57) Abstract:The invention relates to the production of mineral fertilizers in the membranes of humic substances. Humanitariannet fertilizer includes granular fertilizer, HUMATE alkali metal and urea-formaldehyde resin in a ratio of components (wt. %) 95,7 - 96,6, 3,0 - 4,0 and 0.3 to 0.4, respectively; the method of producing fertilizer includes cladding granules of mineral base fertilizer shell of alkali metal HUMATE, after cladding hematopoi shell of the fertilizer granules further treated with a solution of alkali metal HUMATE and urea-formaldehyde resins. The consumption of fertilizers is reduced by improving the digestibility of its plants. 2 S. and 2 C.p. f-crystals. table 1. The invention relates to the production of fertilizers, in particular mineral, and can be used for the manufacture of mineral fertilizers in the membranes of humic substances.Known mineral fertilizers in hematopoi shell based on at least one of the group of fertilizers - urea, super phosphate or potassium chloride, clad biologically active humic drug.Known fertilizers increase the stress (drought, soil salinization and others) at the expense of increasing the digestibility of fertilizers humates.Also known is a method of obtaining mineral fertilizers in hematopoi shell, in which mineral based fertilizers sprayed humic drug, for example an aqueous solution of potassium HUMATE.A disadvantage of the known gumanitarnogo fertilizer and method of its production is the high consumption of fertilizers due to the fact that they do not provide optimal absorption by plants of mineral base fertilizers because of the low content of humus in the shell results in detachment from the fertilizer granules during storage, transportation and fertilizer into the soil.The objective of the invention is to reduce the consumption humated fertilizers by providing the possibility of preventing the detachment of hematopoi shell from granules of mineral base fertilizer.This technical result is achieved by the fact that humanitariannet mineral fertilizer, including granular fertilizer, such as urea, superphosphate or potassium chloride and alkali metal HUMATE, according to the invention further comprises a urea-formaldehyde resin when following the urea-Formaldehyde resin - 0,3-0,4
This technical result is also achieved by the fact that in the method of obtaining gumanitarnogo mineral fertilizers, such as urea, super phosphate or potassium chloride, comprising the cladding of granules of mineral base fertilizer shell of alkali metal HUMATE, according to the invention, after the cladding hematopoi shell fertilizer further treated with a solution of alkali metal HUMATE and urea-formaldehyde resin.Namely processing of the granules gumanitarnogo mineral fertilizers aqueous solution of alkali metal HUMATE and urea-formaldehyde resin provides penetration of humates in the structure of mineral base fertilizer and prevents delamination of hematopoi shell from its surface, thereby stabilizing the content of humates in the shell and, consequently, improve digestibility of plants fertilizer and increase its impact on growth, development and yield of crops while reducing the consumption of fertilizer.The introduction of gumanitarnogo mineral fertilizers urea-formaldehyde resin is justified to improve the adhesion of hematopoi shell with mineral-based fertilizers and polochanka a consequence, the reduced specific consumption and overdose prevention.A reduction in the content of urea-formaldehyde resin is less than the stated does not give the desired effect, as it leads to the production of fertilizers with low content of HUMATE due to insufficient adhesion of hematopoi shell surface of the mineral substrate fertilizer.The increase in the content of urea-formaldehyde resin is above the upper limit was not feasible due to unproductive consumption.Example. Mineral based fertilizers, such as urea in the form of granules with a size of 1-3 mm, treated with powdered potassium HUMATE humidity of 12%, while mixing in a rotating drum.Mixing mineral base fertilizer with potassium HUMATE is carried out at a ratio of 25-30:1 to the acquisition of granules of black or dark brown. Clad with hematopoi shell of the fertilizer granules are sprayed with vigorous stirring 10% solution of potassium HUMATE and urea-formaldehyde resins, enveloping them primary gummatovoy shell of the second layer.Humanitariannet fertilizer dried and then fed to the packaging.The experience gained is of estaline in the table.The table shows that the results obtained by the proposed method humated fertilizer claimed composition (PP 2-4) prevent delamination of hematopoi shell from the surface of the mineral substrate fertilizer and thereby allow a 30% reduction in its consumption.Thus, the use of the proposed gumanitarnogo fertilizer and method of its production compared to existing prevents delamination of hematopoi shell from mineral base fertilizer and thereby reduces the amount of fertilizer by improving the digestibility of its plants. 1.

SUBSTANCE: invention relates to agriculture. The method includes application of mineral fertilisers into the soil, drill sowing of the main spring nurse forage crop, followed by complementary seeding of intermediate forage crop, for example, spring rape, repeated mowing of herbage for animal feed. And after each mowing the stubble is combed and sprayed with insecticides. Sowing of the main spring nurse forage crop is carried out with seeds of sorghum crops, such as Sudan grass or forage millet with low seeding rate up to 50% and 75% respectively. Before sowing, as a mineral fertiliser, a controlled-release carbamide-formaldehyde fertiliser is applied in the soil containing 0.1-0.3 moles of formaldehyde per 1 mol of carbamide. The fertiliser is applied to the soil at the rate of 60-90 kg of active ingredient per 1 ha.
EFFECT: method enables to intensify the growth of plants due to preplant application of controlled-release carbamide-formaldehyde fertiliser and to increase the number of cuttings.
