FIELD: chemistry.
SUBSTANCE: invention relates to methods of producing organomineral fertiliser from wastes of processing enterprises and can be used in agriculture to increase soil fertility and improve soil structure. The method involves obtaining organomineral fertiliser containing an organic substance source and micro- and macronutrients. The organic substance and micro- and macronutrients in the fertiliser are brewing wastes - residual brewing yeast and kieselguhr filter cake, extraction wastes - natural zeolites, chemical industry wastes - phosphogypsum hemihydrate, cement production wastes - cement dust and chalk in ratio (5-31):(1-5):1:(1-2.5):(1-2.5), respectively.
EFFECT: invention enables to obtain fertiliser with prolonged effect, which is environmentally safe and can restore and improve soil structure.
