A controlled release fertilizer composition and methods to produce the controlled release fertilizer composition. The controlled release fertilizer composition includes a fertilizer core that is coated with a polymeric layer, such as polyurethane, that includes an organic carbonate additive.

Fertilizer granules having polymeric coating with organic carbonate

A nutrient or medicinal composition for administration to ruminants, which includes a core of one or more biologically active substances coated with a film of polyurethane, overcoated with an 'intermediate' wax is disclosed. This polyurethane/wax coating is resistant to rumen conditions, but will release the biologically active substance(s) in the abomasum and subsequent digestive tract of the ruminant animal.

Ruminant feed composition and method of making

A controlled release fertilizer material comprising a particulate plant nutrient surrounded by a coating of a mixture including an isocyanate and a polyol, and further comprising a modified wax that may include a polyhydroxyl compound in which the wax and/or the polyhydroxyl compound are cross-linked with a sulfur or oxygen or a peroxide cross-linking moiety. In certain embodiments, the wax and polyhydroxyl compound are cross-linked at unsaturated sites in the wax or polyhydroxyl compound using heat, UV or ionizing radiation.

Cross-linked modified waxes for controlled release fertilizers

A controlled release fertilizer material comprising a particulate plant nutrient surrounded by a coating which is the reaction product of a mixture including a cross-linked polyol, an isocyanate and a wax is described. The cross-linked polyol is a reaction product of a polyhydroxyl compound, such as glycerol, and a triglyceride and the monoglyceride and/or diglyceride products are cross-linked with sulfur, oxygen and/or a peroxide cross-linking moiety, or are directly cross-linked at unsaturated sites in the monoglycerides and/or diglycerides.

Controlled release fertilizers made from cross-linked glyceride mixtures

A granular controlled-release pesticide comprising &ldquo;core&rdquo; granules such as ammonium sulfate, an inner polymer membrane formed in situ on said granules of ammonium sulfate, an acephate pesticide applied to the inner polymer membrane on the core granules, and an outer controlled-release polyurethane membrane formed in situ on said pesticide to permit controlled release of the pesticide.

Controlled-release pesticidal composition and method of making

The present invention described a polymer coated fertilizer, such as urea, subsequently coated with a layer of sulfur and thereafter a further coating of polymer. Preferably, the polymer coatings are formed by the direct in situ co-polymerization of the components of the polymer on the fertilizer and on the sulfur coating. The compositions provide positive controlled release characteristics, are abrasion and impact resistant and are substantially more economical to produce than polymer coated fertilizers.
