The method of producing ammonium-phosphate fertilizers is developed which includes interaction of microelement compounds with nitrogen-phosphate solutions in presence of a stabilizing additive. As the nitrogen-containing reagent and stabilizer water-ammonium extinction from biohumus is used. The matter of the invention is in obtaining an ammonium-humate water solution through treatment with ammonia the products of biological composting (for example, biohumus). First the solution is saturated with microelements (copper, zinc, cobalt, molybdenum, lithium and boron) and afterwards it is neutralized by a phosphorous or polyphosphorous acid up to pH 7.0-7.5. Into the solution potassium and ammonium salts might be entered. The fertilizer obtained has a number of advantages: micronutrients content raises by 10 times; stable concentrated ammonium-phosphate solutions of micronutrients are obtained; as a stabilizer ecologically safe compounds (humates) are used; an universal micronutrient composition is achieved at less energy and labour consumption
