FIELD: chemistry.SUBSTANCE: invention relates to agriculture. The method of producing granular oranomineral nano-fertilisers, which involves mixing dry starting mineral components selected from: carbamide, ammophos, diammonium phosphate, ammonium nitrate, superphosphate, double superphosphate, ammonium sulphate, potassium chloride, potassium sulphate, potash, ground phosphorite; mineral components containing trace elements: Mg, B, Mn, Zn, Cu, Ni, Co, Cr, Mo; and an organic component selected from humic substances, wherein dynamic conditions in the moulding zone - thermobaric conditions in a rotary pelleting press: pressure of 20-35 MPa and temperature of 100-125°C, lead to mechanical and chemical processes to form nano-sized complexes of humic substances with mineral components of the mixture, having growth stimulant properties, prolonged action and high biological activity.EFFECT: invention enables to obtain granular organomineral nano-fertilisers using an energy-saving, single-step wasteless technique, wherein the granules have excellent mechanical properties, do not clump, are nonhygroscopic; the activated humic complexes encapsulated into the granules do not aggregate and do not lose biological efficiency during storage.5 cl, 7 dwg, 7 tbl |
