PCT No. PCT/DE95/00243 Sec. 371 Date Aug. 13, 1996 Sec. 102(e) Date Aug. 13, 1996 PCT Filed Feb. 20, 1995 PCT Pub. No. WO95/22514 PCT Pub. Date Aug. 24, 1995This patent describes nitrification inhibitors characterized by the fact that they contain as their active ingredients a substituted pyrazole, or a salt or metallic complex thereof, dicyanodiamide, and one of the compounds ammonium thiosulfate, biguanide, or ammonium rhodanide. The combinations of the present invention are more efficacious than the individual ingredients alone and binary combinations of the same ingredients, and are thus superior to same from the ecological, phytotoxicity, and cost-effectiveness stand-points, as well as in terms of their tendencies to form undesirable residues.
