摘要： A renewable material-based furandicarboxylic acid (Bio-FDCA) coating material of a polyurethane controlled release fertilizer is prepared by performing cross-linking reaction between at least one polyester polyol and at least one isocyanate, wherein the polyester polyol is made from the Bio-FDCA. Moreover, a method for preparing a polyurethane controlled release fertilizer includes by spraying the coating material on a surface of granular fertilizer, forming a layer of film after cross-linking in situ on the surface of the granular fertilizer, so as to obtain the polyurethane controlled release fertilizer. In the present invention, it is the first time to introduce the furan ring structure into the coating material of the polyurethane controlled release fertilizer, and the Bio-FDCA is taken as the source of the furan ring structure.

摘要： 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. 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.
