METHOD FOR PRODUCING GRANULAR INTEGRATED ORGANOMINERAL FERTILIZER AND SAPROPEL-CONTAINING GEL FOR ITS PRODUCTION Russian patent published in 2023 - IPC C05F7/00 C05C9/00 C05G3/00 

FIELD: agriculture.

SUBSTANCE: method for producing granular integrated organomineral fertilizer involves treating a sapropel-containing product with mineral components, and as a sapropel-containing product, a crushed dry mixture containing 95-98 wt.% sapropel is used, the rest is mineral components, a sapropel-containing gel is obtained with sapropel particle sizes from 5 to 10 μm by crushing the sapropel in a vortex mill followed by cavitation dispersion of sapropel in an aqueous solution of caustic potassium and urea, the crushed dry mixture is moistened with sapropel-containing gel in the following ratio of components: sapropel-containing gel - 10-15 wt.%, dry mixture - 85-90 wt.%, granulated for at least 60 minutes, during which wetting, rounding and formation of granules occurs, then dried at a temperature of no more than 50°C and get fertilizer granules with a porosity of 35-70%. Sapropel-containing gel used to produce granular integrated organomineral fertilizer using this method.

EFFECT: increasing the efficiency of fertilizer.
