ABSTRACT:
A method of coating urea by first wetting urea pellets with water or an aqueous acid solution, and then blended the wetted urea pellets with a phosphate salt. During the coating process, when using an aqueous acid solution, the acid liberates a portion of the phosphate to a form available to the plant, and reduces the loss of urea nitrogen due to volatilization.
