Abstract
A slow release particulate fertilizer product in which the fertilizer particles are encapsulated with a sulfur coating. The sulfur coating is substantially crystalline and contains in admixture therewith from 0.05 to 2% (by weight of the coating) of a substituted symmetrical dialkyl polysulfide plasticizer as the sole organosulfur compound in the admixture. Fertilizer efficiency over standard sulfur coatings improves typically 40-50% with the plasticized sulfur coatings.
