FIELD: chemistry.
SUBSTANCE: method of producing organomineral fertiliser involves composting liquid cattle manure, intra-farm wastes, soil, straw and chemical production wastes - phosphogypsum. Said components are layered onto a packed clay platform with a depressed bottom in the following ratio in wt %: liquid cattle manure 65-70, soil 5-8, intra-farm wastes 2-5, phosphogypsum 15-20, straw - the rest. The mixture is mixed every month for 4-4.5 months before maturation.
EFFECT: method enables to obtain organomineral fertiliser with retention of organic substance, moisture and nitrogen, which has a positive effect on the soil and crop yield.
