ABSTRACT 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.
