FIELD: chemistry.
SUBSTANCE: invention relates to agriculture. The method of producing granular conditioned fertiliser involves granulation, drying the granules, sorting with separation of the commercial-grade fraction, cooling said fraction and adding a dry powdering substance, wherein the granules are powdered during packing, the powdering substance used being peat which is modified by heating to 150-200°C for 5-60 minutes, with particle size of 5-500 mcm, in concentration of 1-5 wt %.
EFFECT: invention reduces the cost of producing mineral fertiliser, prolongs storage life without change in physical and chemical properties thereof.
