The present invention relates to a coated granular substance, wherein the coating comprises a resin comprising the reaction product of a polyol component and an isocyanate component and cured by the addition of a catalyst, said catalyst comprising a hydroxy group-containing amine compound. Further, the present invention relates to a process for coating a granular substance, comprising the steps of (a) providing a granular substance; (b) providing a polyol component and an isocyanate component; (c) optionally mixing the polyol component with the isocyanate component; (d) adding the mixture of step (c) or the polyol component and the isocyanate component as individual substances to the provided granular substance and producing a coating on the granular substance; (e) adding a catalyst to cure the coating; (f) optionally repeating steps (d) and (e), wherein the catalyst comprises a hydroxy group-containing amine compound.

Polymeric compositions useful for use with solid or liquid phosphate fertilizers include one or more first copolymers having at least two repeat units selected from maleic, itaconic, and sulfonate repeat units, and one or more second copolymers having maleic and olefinic repeat units. The compositions are capable of synergistically reducing or eliminating phosphate fixation, and are relatively low in cost. The compositions may also be supplemented with product-marking dyes and second copolymers having high and low molecular weight profiles in order to control fines or dust during handling and application of solid phosphate fertilizers.
