FIELD: agriculture.
SUBSTANCE: method for producing capsular fertilisers by treating urea granules with sodium silicate and calcium chloride solutions with a stoichiometric ratio of the components is characterised by the use of a complex compound hydroquinone — a urease activity inhibitor, and copper (II) sulphate — a fungicide, wherein hydroquinone is added in the amount of 0.08 wt.%, and copper (II) sulphate in the amount of 0.5 wt.% to the aqueous solution of sodium silicate.
EFFECT: production of a fertiliser — capsular urea of prolonged action with a urease activity inhibitor (hydroquinone) and a fungicide (copper (II) sulphate).
