METHOD OF PRODUCING GRANULAR ORGANOMINERAL FERTILIZER Russian patent published in 2022 - IPC C05F11/02 A01C21/00 C05C9/00 C05B17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Method of producing granular organomineral fertilizer involves mixing peat with mineral components, granulation, cooling, packaging, wherein peat with moisture content of 75–85 % is used, peat is ground to fraction of 500 microns in a grinder and loaded into a mixer, mixed successively with diatomite, carbamide-ammonium nitrate, phosphorite meal, wood ash, wherein mixing after each added component is carried out for 3 to 5 minutes, mixture of components is thoroughly mixed for 10 minutes, obtained mass with moisture content of 35–37 % and dry substances content of not more than 50 % is crushed and granulated to form rounded granules with size from 2.5 to 4.5 mm, followed by pelletizing, granules are dried and cooled, fed into a sieving machine by means of a conveyor, treated with a humic preparation in a humatizing chamber and supplied to packaging.

EFFECT: invention makes it possible to create granular organomineral fertilizer, balanced by composition, which improves agrophysical properties of soil, increases yield, quality of cultivated agricultural products.
