摘要： An improved homogenous granular fertilizer composition is disclosed; the composition is comprised primarily of urea, N-(n-butyl)thiophosphoric triamide (NBPT), and dicyandiamide (DCD). The composition of this invention can be applied to a field crop in a single surface application and will nevertheless supply sufficient nitrogen to the plants throughout their growth and maturing cycles. The new improved composition increases the nitrogen uptake by plants, enhances crop yields, and minimizes the loss of both ammonium nitrogen and nitrate nitrogen from the soil.The NBPT is incorporated into the homogenous granular fertilizer composition of this invention by blending a concentrated solution of NBPT in a solvent selected from the group consisting of liquid amides, 2-pyrrolidone, and N-alkyl 2-pyrrolidones directly into molten urea prior to its granulation; the DCD may be added to the urea melt as a solid or in dissolved form along with the NBPT.
摘要翻译： 公开了一种改进的均匀颗粒肥料组合物; 该组合物主要由尿素，N-（正丁基）硫代磷酸三酰胺（NBPT）和双氰胺（DCD）组成。 本发明的组合物可以在单一表面施用中应用于田间作物，并且在其生长和成熟周期期间将向植物提供足够的氮。 新的改进的组合物增加植物的氮吸收，增加作物产量，并最小化来自土壤的铵氮和硝态氮的损失。 NBPT通过将NBPT的浓缩溶液在选自液体酰胺，2-吡咯烷酮和N-烷基2-吡咯烷酮的溶剂中直接掺入到熔融尿素中之前，将NBPT掺入本发明的均匀颗粒肥料组合物中 制粒 DCD可以与NBPT一起作为固体或溶解形式加入到尿素熔体中。

摘要： Improved solvent systems for the formulation of N-alkyl thiophosphoric triamide urease inhibitors. These formulations enable the preparation of stable concentrated solutions of N-alkyl thiophosphoric triamides for storage, transportation, and eventual impregnation onto solid urea containing fertilizers and incorporation into liquid urea containing fertilizer compositions. These formulations are comprised primarily of a solvent selected from the group consisting of glycols and glycol derivatives. Optionally, in addition to the glycol base solvent, the formulations can contain a co-solvent selected from the group consisting of liquid amides, 2-pyrrolidone and N-alkyl 2-pyrrolidones, and/or a nonionic surfactant selected from the group consisting of alkylaryl polyether alcohols. The presence of the co-solvent and/or surfactant has been found to impart desirable properties to the formulations under certain conditions. N-alkyl thiophosphoric triamides have been known for some time to be effective inhibitors of the activity of urease enzymes, however, commercial use has been inhibited by the lack of an acceptable carrier. They are often thermally and hydrolytically unstable and difficult to handle. The use of the solvent systems offers many advantages including: (1) improved stability of the active ingredient urease inhibitor; (2) excellent solubility characteristics; (3) extremely low flammability and toxicity of the solvents; (4) excellent cold temperature storage and handling characteristics with the addition of the liquid amide co-solvent; and (5) good adsorption characteristics onto solid urea containing fertilizers and excellent miscibility with liquid urea containing fertilizer formulations.

摘要： An improved aqueous nitrogen fertilizer has been developed that increases first-year nitrogen uptake efficiency to plants. It is also a nitrogen fertilizer with features to minimize exposure to nitrogen loss. It is a nitrogen fertilizer consisting of urea, dicyandiamide, ammonium thiosulfate, and optionally a phosphate compound which is preferably an ammonium phosphate compound. This composition can contain a dye and/or various mineral micronutrients. This homogeneous granular fertilizer can be applied to a field crop in a single application and is available to the growing plant throughout its growth and maturing cycle. The homogeneous granular fertilizer composition is conveniently prepared by the addition of a dicyandiamide, and a solution of ammonium thiosulfate to molten urea. A phosphate compound and preferably ammonium polyphosphate, would be added along with these components.

摘要： An improved aqueous nitrogen fertilizer has been developed that increases first-year nitrogen uptake efficiency to plants. It is also a nitrogen with features to minimize exposure to nitrogen loss. It is a nitrogen fertilizer consisting of urea, ammonium nitrate, dicyandiamide, ammonium thiosulfate, and a phosphate compound which is preferably an ammonium phosphate compound. This composition can contain a herbicide and/or various micro nutrients. This aqueous fertilizer solution can be applied to a field crop in a single application and is available to the growing plant throughout its growth and maturing cycle. The aqueous fertilizer composition is conveniently prepared by the addition of a slurry containing dicyandiamide, ammonium thiosulfate and the phosphate compound to a urea-ammonium nitrate solution wherein the nitrogen content has been adjusted to account for the nitrogen that will be supplied by the slurry.
