FIELD: agriculture, in particular, processes for manufacture of organic-mineral fertilizers.
SUBSTANCE: method involves dosing, grinding, mixing, granulating and drying components; mixing organic raw material constituting at least 40% by weight of ready fertilizer, mineral additives constituting at least 15% by weight of ready fertilizer; granulating organic-mineral mass by means of screw-type extruder and drying granules in apparatus where flowing layer is created and gases are supplied at temperature ranging between 200 C and 750 C. Organic raw material is peat or organic mud.
EFFECT: increased homogeneity of composition and stable sizes of granules of granulated fertilizer.
