FIELD: agriculture.
SUBSTANCE: invention relates to the agriculture. Method of producing slow-acting encapsulated fertilizers by treating urea granules with solutions of sodium silicate and calcium chloride with stoichiometric ratio of components with urease inhibitor addition, wherein the urease activity inhibitor used is paraaminophenol, wherein the urease activity inhibitor is introduced in amount of 0.002–0.08 wt% into an aqueous solution of sodium silicate used in the composition for coating granules.
EFFECT: invention enables to obtain encapsulated urea with prolonged action.
