  • Patent number: 9163110
    Abstract: A coated granule is obtained by coating a bioactive substance-containing granule with a urethane resin obtained by reaction of an aromatic diisocyanate with a polyol mixture containing a polyesterpolyol and a C2-C8 polymethylene glycol, wherein the molar ratio of the polyesterpolyol to the polymethylene glycol is 1:20 to 20:1. The granule is capable of controlling elution of the bioactive substance appropriately, and the urethane resin forming the coating film shows degradability in soil.

  • Patent number: 9073798
    Abstract: The present invention relates to plant fertilizer compositions and methods that may be used over the growth and blooming or fruiting stage of plant life. In some aspects, the present invention relates to blending plant fertilizer constituents and more particularly, the present invention relates to tailoring the ratio of nutrients in a fertilizer composition by colorizing fertilizer constituents according to their nutrient content and mixing the colorized fertilizers until the resultant color matches a reference color associated with a desired fertilizer composition. In other aspects, the present invention relates to plant fertilizers that avoid the unavailability of calcium due to precipitation, and in additional aspects, dual-component plant fertilizers and related kits and methods are provided that permit admixing of only two fertilizer concentrates while avoiding deleterious precipitation of reactive moieties.

  • Patent number: 9056940
    Abstract: The invention provides polyester polyol compositions and resin blends, useful as components of polyurethane and polyisocyanurate polymers, produced from cyclohexane oxidation reaction byproducts, such as water extracts and non-volatile distillation residues from the reaction. Such byproducts of industrial processes for preparation of adipic acid and caprolactam, important intermediates in the production of various types of nylon, have hitherto largely been used only as fuels. The present invention provides value-added products, methods for making, and methods for using the byproduct-derived polyester polyol compositions. For example, the invention provides polyurethane (PU) and/or polyisocyanurate (PIR) polymers made using the polyol compositions and polyfunctional isocyanates. The PU and PIR polymers can be used as adhesives, binders (e.g., for wood fibers), coatings (e.g., for controlled release fertilizers), and foams.

  • Publication number: 20150143860
    Abstract: Increasing longevity of the nitrogen content of soil through improved liquid delivery formulations of urease inhibitors and/or nitrification inhibitors designed to apply to fertilizers, especially urea and manure based fertilizers These delivery formulations provide an environmentally sound and inherently safe solvating system that improves the storage stability of the urease inhibitors by utilizing aprotic solvents, maintain the urease inhibitors and/or nitrification inhibitors in solution to storage temperatures of at least 10° C. and provides improved application to fertilizer of urease and/or nitrification inhibitors. These delivery formulations enable safe storage, transport and subsequent application or blending with urea based or manure based fertilizers that can be applied to soil in either a liquid or granular form to provide improved nitrogen retention in the soil for uptake for plant life.
