PRECURSOR COATINGS FOR SULFUR COATED CONTROLLED RELEASE FERTILIZERS

摘要

A controlled release sulfur coated fertilizer with improved abrasion resistance is produced by applying a precursor coating that forms a cohesive film which adheres to the fertilizer substrate particles and to the sulfur that is subsequently applied in molten form. The improved fertilizer also optionally comprises a sealant coating applied after the molten sulfur. This invention is to the composition of the fertilizer and the method of production.
