Abstract

See full text

The present invention relates to increasing and/or maintaining nitrogen content in soil by administration of nitrogen sources particles coated with urease inhibitors. In one embodiment, urease inhibitors are dispersed in an improved organo liquid delivery system at concentration levels of 60-95%. In another embodiment, urease inhibitors were applied in a non-aqueous, organo liquid delivery system coating nitrogen sources particles utilizing simple blending equipment at temperatures of 20°-70° C. Another embodiment discloses dry, flowable nitrogen sources coated with a urease inhibitor which can be administered directly to the soil, to a dry natural and/or a manmade fertilizer or to a liquid fertilizer which provides for the reduction of nitrogen loss from the soil. In another embodiment, a composition of urea and <0.2% dimethyl sulfoxide improves the crush resistance of the urea particles.
