FIELD: technology of fertilizers and food additions. SUBSTANCE: method involves preliminary liquid separation by settling to moisture content of mass 80-85%, liquid separation by pressing, granulation and the following drying in boiling layer at heat carrier feeding at 300-350 C. At pressing liquid is separated to moisture content of mass 30-39% and drying is carried out to moisture content of product 0.84-0.89%. Content of effective nutrient components in obtained product is the following, wt.-% (by dry matter): ammonium nitrogen 0.35; total nitrogen 10.5-10.9; phosphorus (by P<SB>2</SB>O<SB>5</SB>) 1.49-1.54; potassium (by K<SB>2</SB>O) 3.75, and protein 35-38. EFFECT: improved method of treatment. 2 cl, 1 tble
