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.
摘要翻译：已经开发了改进的含氮氮肥，其提高了植物的第一年氮吸收效率。它也是一种具有最小化氮损失暴露的特征的氮。它是一种由尿素，硝酸铵，双氰胺，硫代硫酸铵和优选磷酸铵化合物的磷酸盐化合物组成的氮肥。该组合物可含有除草剂和/或各种微量营养物质。这种含水肥料溶液可以在单一应用中应用于田间作物，并且在其生长和成熟周期中可用于生长的植物。通过将含有双氰胺，硫代硫酸铵和磷酸盐化合物的浆料加入到硝酸铵 - 硝酸铵溶液中，其中氮含量已经被调整以考虑由浆料供应的氮气，方便地制备了含水肥料组合物。
