Beschreibung
Zusammenfassung:	The present invention relates to a solid composition (1) comprising (A) a mixture comprising N-(n-butyl)thiophosphoric acid triamide (NBPT) and optionally N-(n-propyl)thiophosphoric acid triamide (NPPT); (B) a solvent selected from the group consisting of glycol ether, glycerin ether, and mixtures thereof; and (C) urea, wherein the solid composition (1) is polymer free. Further, the present invention relates to the use of a solvent selected from the group consisting of glycol ether, glycerin ether, C3-C10-alkanediol, carboxylic acid amide, and mixtures thereof for stabilizing at least one (thio)phosphoric acid triamide in a solid composition (1) comprising a mixture (A) comprising the at least one (thio)phosphoric acid triamide, urea, and the solvent.
