Granular fertilizer compositions are described herein that are capable of supplying a wide array of beneficial nutrient and compounds to soil for uptake by the root systems of plants. In preferred embodiments, the compositions provide a source of phosphorus, a source of nitrogen, a source of boron, a source of copper, a source of manganese, a source of zinc, and a source of sulfur in a single application, with highly efficient uptake by plants. The compositions generally comprise a mixture of two or three types of granules, each providing a supply of one or more nutrients. It has been discovered that the components of the three types of granules interact in a synergistic manner, such that problems associated with certain nutrients in soil are overcome, thereby providing a highly efficient multi-nutrient fertilizer.

The present invention is a liquid fertilizer comprising a calcium cyanamide component that is dissolved, co-applied, dispersed, or suspended in a solution of aqueous triazone urea. The combination of calcium cyanamide and triazone urea produces a slow release of nitrogen that requires fewer reapplications and is more effective than heretofore fertilizers. In one preferred embodiment, the fertilizer or plant treatment is further combined with a soil treatment including polycarboxylate acids and polyaliphatic acid salts in combination with potash to further enhance the properties of the fertilizer.

A fertilizer-application method comprises (a) receiving an aqueous solution of a cyanamide compound into a heated segment of a hydrolyzer; (b) allowing the cyanamide compound to hydrolyze in the heated segment, thereby forming an aqueous cyanamide hydrolysate (ACH); (c) allowing the ACH to cool under pressure; and (d) applying the ACH, after cooling, to soil.

The present subject matter relates to a stable pesticidal formulation which exhibits improved dispersibility in cold water and full compatibility with fertilizers.
