  • Publication number: 20220411346
    Abstract: The present invention relates to increasing longevity of the nitrogen content of soil through improved liquid delivery formulations of nitrification inhibitors. The liquid formulation can also be comprised of nitrification inhibitors and optionally urease inhibitors that are blended solutions of each. The nitrification inhibitors are present in a mixture that comprises both a protic and an aprotic solvent system. The novel formulations are designed to be applied to fertilizers, especially urea and manure based fertilizers. The delivery formulations provide an environmentally sound and inherently safe solvating system that improves the storage stability of the urease inhibitors by utilizing liquid organic non-water containing solvents, maintains the nitrification inhibitors in solution to storage temperatures of at least 10° C., and provides improved application to fertilizer of nitrification inhibitors.

  • Patent number: 10301230
    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.
