ABSTRACT:
A delayed release fertilizer composition consisting essentially of a mixture of a urea-formaldehyde resin and a lignosulfonate prepared by spray-drying an aqueous mixture of a urea-formaldehyde resin and a lignosulfonate. The composition of this invention, is also use as a fertilizer carrier as a replacement for expanded vermiculite fertilizers.
