ABSTRACT:
The present invention describes a sulfur-coated urea slow release granular fertilizer having a uniform, durable polymeric coating over the sulfur-coating. The polymer coating is formed by the direct in situ co-polymerization of diethylene glycol-triethanolamine polyol and a diisocyanate on the surface of the sulfur-coated urea granule. The polymeric coating provides improved impact resistance of the composite coated granule.
