Abstract

The invention relates to a complex nitrogen-phosphorus-potassium NPK-fertilizer, where mass fraction of total nitrogen is from 13-15%, mass fraction of total phosphates, in terms of P2O5, is from 9-10%, mass fraction of potassium, in terms of K2O, is from 13-15%, and also to method for the preparation of said fertilizer from a solid phosphate salt, being a mixture of fluorapatite Ca5(PO4)3F and dicalcium phosphate CaHPO4 x nH2O, where n is 0 to 2, with fluorapatite Ca5(PO4)3F content from 27% to 99%, using various potassium and ammonium salts as a source of nutrients in the fertilizer. The technical result is providing enhanced properties of NPK-fertilizer, in particular a method for its production allows to improve the strength of granules, solve the problem related to the plasticity of granulated complex fertilizers, improve water solubility of phosphorus contained in the fertilizer by 98%, thereby improving consumer properties of NPK-fertilizers.
