FIELD: agriculture, in particular, processing of animal wastes for further usage as fertilizers. SUBSTANCE: method involves chemical fixation of ammonia nitrogen by phosphogypsum through uniform dissipation of phosphogypsum over layer of manure scattered by manure scattering unit at the rate of 30 kg per 1 t of manure. Phosphogypsum is dissipated by manure applicator. This procedure is performed during field works in autumn or in spring, when ambient air temperature does not exceed 10-15 C. EFFECT: increased yield by increased manure fertilizer capacity and elimination of ammonia nitrogen loss. |
