ORGANOMINERAL FERTILIZER AND METHODS OF ITS APPLICATION FOR AGRICULTURAL CROPS Russian patent published in 2021 - IPC C05D9/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, namely to organic fertilizers. Organomineral fertilizer contains macroelements nitrogen and sulfur, microelement boron, trace elements of iron, zinc, copper, cobalt, manganese in a chelated form formed by the interaction of metals with a chelating agent, while L-aspartic acid is selected as a chelating agent, and the fertilizer additionally contains molybdenum and carbon with the following ratio of the starting components (wt.%): L-aspartate iron - 31.9-47.9, L-aspartate zinc - 13.9-20.9, L-aspartate copper - 5.9-8.9, L-aspartate cobalt 0.6-1.0 , Manganese L-aspartate - 15.3-22.9, boron - 2.08-3.12, molybdenum - 0.008-0.012, nitrogen - 7.7-11.5, sulfur - 4.4-6.6, carbon - 13.1-19.7. Organomineral fertilizer is used in the method for processing vegetable and melon crops for pre-sowing treatment of seeds or tubers or bulbs with a working solution at a concentration of 0.010-0.043 kg per 10 liters of water at a consumption of 1.0-2.0 liters per 1 kg of seeds or tubers or bulbs, for foliar top dressing at a fertilization rate of 0.25-0.43 kg/ha by spraying with a working solution at a flow rate of 200-800 l/ha and root top dressing at a fertilization rate of 1.0-4.3 kg/ha. In addition, organomineral fertilizer is used in the method for processing cereals, legumes, industrial and forage crops for pre-sowing treatment of seeds with a working solution at a concentration of 0.010-0.043 kg per 10 liters of water at a consumption of 10 liters per 1 ton of seeds, foliar feeding at a fertilization rate of 0, 25-0.43 kg/ha by spraying with a working solution at a flow rate of 200-800 l/ha and a frequency of treatments 1-6 times.

EFFECT: proposed organomineral fertilizer and method for processing agricultural crops accelerate the formation of seedlings and root mass while improving the quality of agricultural products and increasing yields.
