SUBSTANCE: method of manufacturing complex granulated mineral fertilizer consists in mixing ammonium nitrate and monoammonium phosphatecontaining phosphate additive. The latter is granulated mineral double fertilizer simultaneously containing ammonium nitrate, monoammonium phosphate, and calcium phosphates at total content of digestible phosphorus 13#247;21% (calculated as
The present invention relates to a process for the manufacture of monopotassium phosphate using solvent extraction technique. According to the invention, the reaction occurs between phosphoric acid and potassium chloride at a temperature between 0 and 100 degrees C. in the presence of an organic solvent comprising a long chain primary amine having between 6 to 28 carbon atoms.
