The present invention relates to increasing longevity of the nitrogen content of soil through improved liquid delivery formulations of nitrification inhibitors. The liquid formulation can also be comprised of nitrification inhibitors and optionally urease inhibitors that are blended solutions of each. The nitrification inhibitors are present in a mixture that comprises both a protic and an aprotic solvent system. The novel formulations are designed to be applied to fertilizers, especially urea and manure based fertilizers. The delivery formulations provide an environmentally sound and inherently safe solvating system that improves the storage stability of the urease inhibitors by utilizing liquid organic non-water containing solvents, maintains the nitrification inhibitors in solution to storage temperatures of at least 10° C., and provides improved application to fertilizer of nitrification inhibitors. These delivery formulations enable safe storage, transport and subsequent application or blending with urea-based or manure-based fertilizers that can be applied to soil in either a liquid or granular form to provide improved nitrogen retention in the soil for uptake for plant life.

An inhibitor composition contains dicyandiamide as a nitrification inhibitor, alkyl thiophosphoric triamide as a urease inhibitor, or a combination thereof, dissolved in a liquid medium comprising an organic solvent selected from, among others, one or more polar aprotic solvents, including one or more organophosphates, amine solvents, heterocyclic alcohol solvents, and mixtures thereof, is useful in making fertilizer compositions and in a method of fertilizing target plants.
