1. A liquid urease inhibitor formulation for application to urea-based fertilizers and waste containing urea compounds comprising:
(a) a urease inhibitor selected from the group consisting of N-substituted thiophosphoric triamides and N-substituted phosphoric triamides represented by Structure I and mixtures thereof, wherein X=O or S, R1=unsubstituted and substituted C4-C6 alkyl, unsubstituted and substituted C5-C8 cyclo alkyl, phenyl and substituted phenyl having a nitro, amino, alkyl, or halide substituent; and Y=H, NO2, halide, NH2 or C1 to C8 alkyl; and (b) a primary solvent selected from the group consisting of dialkyl sulfones according to Structure II, polymethylene cyclic sulfones according to Structure III, and mixtures thereof; wherein the urease inhibitor is soluble in the primary solvent. |
