FIELD: chemistry.
SUBSTANCE: invention relates to agriculture. The method of producing magnesium phosphate fertiliser, which involves melting a mixture of natural calcium phosphates, olivine and dolomite, wherein 2.0-6.0 wt % aqueous solution of liquid glass, containing 23.0-26.0 wt % free colloidal silica, and 1.0-2.0 wt % belite are added to the mixture, and the mixture is melted at temperature of 1240-1300°C.
EFFECT: invention lowers the melting point of the mixture in the fertiliser while maintaining a high degree of conversion of magnesium oxide to a form that is assimilable by plants.
