METHOD OF PRODUCING ORGANOMINERAL COMPLEX FERTILIZER Russian patent published in 2019 - IPC C05D9/00 C05F11/02 C05G3/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the agriculture. Method of producing organomineral complex fertilizer based on an adsorption additive in form of treacle is characterized by mixing aluminum hydroxocomplex solution with potassium K₃[Al(OH)₆] with quail, bringing the obtained suspension to boiling point and neutralizing it with phosphoric acid, wherein at the last step, combining the complex sorbent obtained from the rottenstone, and a suspension of hydrolyzed peat, which is an organic nitrogen containing fertilizer fraction, with further grinding and drying the mixture, wherein at the stage of producing the organic nitrogen-containing fertilizer fraction peat is treated with 25 % potassium hydroxide KOH solution in ratio of peat: potassium hydroxide equal to 1:2.6, and during boiling in a water bath for 1.5 hours, then the obtained organic mixture is neutralized with 30.7 % solution of H₃PO₄ to pH 7, additionally introduced into the mixture are following ingredients: urea CO(NH₂)₂ and microelements in form of boric acid H₃VO₃ and ammonium molybdate (NH₄)₆Mo₇O₂₄⋅4H₂O. All components are taken at a certain ratio.

EFFECT: invention allows to increase soil fertility, to regulate dosage introduction of microelements and simultaneously to absorb with high selectivity from soil toxic components and radioactive elements.
