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.

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： 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.
摘要翻译：改进的用于制备N-烷基硫代磷酸三酰胺脲酶抑制剂的溶剂体系。这些制剂使得能够制备N-烷基硫代磷酸三酰胺的稳定浓缩溶液，用于储存，运输和最终浸渍到固体含尿素肥料上并掺入含有液体尿素的肥料组合物中。这些制剂主要由选自二醇和二醇衍生物的溶剂组成。任选地，除了二醇基溶剂之外，制剂可以含有选自液体酰胺，2-吡咯烷酮和N-烷基2-吡咯烷酮的共溶剂，和/或选自以下的非离子表面活性剂：烷基芳基聚醚醇。发现共溶剂和/或表面活性剂的存在在某些条件下赋予制剂所需的性质。 N-烷基硫代磷酸三酰胺已知已有一段时间是有效的尿素酶活性抑制剂，然而商业用途已被缺乏可接受的载体所抑制。它们通常是热和水解不稳定的并且难以处理。使用溶剂系统具有许多优点，包括：（1）提高活性成分脲酶抑制剂的稳定性; （2）优异的溶解度特性; （3）溶剂的易燃性和毒性极低; （4）通过加入液体酰胺共溶剂，具有优异的低温储存和处理特性; 和（5）对固体含尿素肥料的吸附性能优异，与含有液体尿素的肥料配方具有优异的混溶性。
