FIELD: agriculture. SUBSTANCE: a complex suspended fertilizer is prepared by adding coquina lime to a 40-56% nitria acid used in an amount of 100 to 120% of the stoichiometric amount. Monoammonium phosphate is predissolved in said nitric acid to maintain P2O5 content in the final product at 1-10% The resulting mixture is maintained under agitation for 2 or 3 hours, and then neutralized with a liquid nitrogen fertilizer solution having 27-33% of total nitrogen and/or 5-25% of ammonia water. EFFECT: improved properties of the suspended fertilizer. 1 tbl
