成果简介	NOVELTY - Multilayer fertilizer of prolonged action is characterized by the fact that it contains a core, which is a granule of mineral fertilizer—carbamide, a first coating layer applied on it, which is a sulfur melt, and a second coating layer applied on the first layer, which is bitumen in the form of a solution in an organic solvent or a mixture of organic solvents, wherein the first coating layer makes 40–45% of the granule weight, the second coating layer makes 0.01–0.04% of the granule weight. Method of producing multilayer fertilizer of prolonged action, containing core, which is a granule of mineral fertilizer—carbamide, a first coating layer applied on it, which is a sulfur melt, and a second coating layer applied on the first layer, which is bitumen in the form of a solution in an organic solvent or a mixture of organic solvents, wherein the first coating layer is 40–45% of the granule weight, second coating layer is 0.01–0.04% of granule weight, consists in the fact that on heated to 60–65°C granules of mineral fertilizer—carbamide using a pelletizing method, sulfur melt is sprayed at temperature of 150°C, thereafter, a second layer is sprayed onto the sulfur coating at ambient temperature, which is a solution of bitumen in an organic solvent or a mixture of organic solvents. USE - Agriculture. ADVANTAGE - Inventions make it possible to increase prolonged effect of fertilizer and reduce negative effect on environment. 6 cl, 6 dwg, 5 ex
