FIELD: agriculture.
SUBSTANCE: invention relates to fertiliser with controlled release of nutrients. Coated granular fertiliser with controlled release of nutrient substances obtained by application of coating on granules of water-soluble fertiliser containing at least one nutrient based on nitrogen, where coating contains a mixture of epoxy resin with low molecular weight between 100 to 400 in amount of 50 to 85 wt%/wt, imidazole derivative in an amount of 1 to 20 wt%/wt, and a modifier in amount of 10 to 30 wt%/wt, modifier is an alkyl ester of vegetable oil.
EFFECT: preventing sticking of granules of fertiliser, slower release nutrients.
