A novel composition is disclosed, comprising (a) an aqueous solution of an N-P or N-P-K fertilizer and (b) an attapulgite clay. The composition provides improved emulsion stability when combined with an emulsifiable concentrate of an organophosphorus compound of the formula <IMAGE> in which R1 is selected from the group consisting of C1-C6 alkyl, C1-C6 alkoxy, and C1-C6 alkylthio, R2 is selected from the group consisting of C1-C6 alkyl, C1-C6 alkoxy, and C1-C6 alkylthio, R3 is selected from the group consisting of C1-C6 alkyl, C2-C8 alkylthioalkyl, phenyl, and C7-C12 phenylthioalkyl, the phenyl rings optionally substituted with halogen, C1-C3 alkyl, nitro, or C1-C3 alkylsulfinyl, X is oxygen or sulfur, and Y is oxygen or sulfur.
