  • Publication number: 20240101494
    Abstract: The present invention relates to improving the efficacy of man-made and/or natural organic-based animal manure fertilizers by administration of an organic solvent formula containing polyorganic acids and/or their salts. The formulation liberates nutrient(s) that are normally bound in the soil as insoluble salts and complexes. These delivery formulations also provide an environmentally sound and inherently safe solvating system that improves diffusion of polyorganic acids to the granule fertilizer. These delivery formulations enable safe storage, transport and subsequent application or blending with solid or liquid fertilizers. The combined formulation and fertilizer can be applied to soil to provide improved efficacy of fertilizer by liberating nutrients bound in the soil for uptake by plant life.

  • Publication number: 20230140913
    Abstract: Animal waste contains most of the essential nutrients required for plant growth. However, animal waste also contains microbes that convert urea to ammonium ions, nitrification of the ammonium ions to NO2 and NO3 and denitrification of NO2 or NO3 to N2. N2O is produced as an intermediate of nitrification and denitrification processes and N2O is a 300 times more potent greenhouse gas than CO2. The instant invention discloses low-cost, fluid suspension compositions comprising a combination of urease, nitrification and denitrification inhibitors that decrease the loss of nitrogen from animal waste and lessen the biological formation of the greenhouse gas N2O. These compositions comprise nitrogenous phosphoryl compounds and nitrification inhibitors that utilize manufacturing processes for the formation of low cost, fluid suspensions comprising one or more inhibitor particles selected from the group consisting of urease inhibitor particles, b) nitrification inhibitor particles, and c) fused particles.

  • Publication number: 20220242802
    Abstract: 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.
