The present invention relates to a mixture comprising a) a (thio)phosphoric acid triamide (2) according to the general formula (I) wherein X1 is O or S; R1 is C6-C20-aryl, optionally substituted with electro-withdrawing groups (EWG) selected from the group consisting of fluoro (-F), chloro (-CI), bromo (-Br), iodo (-I), halogenalkyl, trihalomethyl, trifluoromethyl, trichloromethyl, tribromomethyl, nitro (-NO2), cyano (-CN), carbonyl (-(C=0)R7), ammonium (-NhV), and substituted ammonium (-N(R8)3+); R2 is H, C1-C20-alkyl, C3-C20-cycloalkyl, C6-C20-aryl, C6-C20-aryl-C1-C4-alkyl, or C1-C6- (di)alkylaminocarbonyl; R3, R4, R5, and R6 are independently of each other selected from the group consisting of H and C1-C4-alkyl; R7 is H, halogen, alkyl, aryl, hydroxy, alkoxy, aryloxy, carbonyloxy, or amino; and R8 is H, alkyl, or aryl; and b) a fertilizer mixture (3) comprising a urea-containing fertilizer (3a) and an additional P-containing fertilizer (3b) which is preferably a NPK fertilizer, a NP fertilizer, a PK fertilizer, or a P fertilizer.
