The invented composition for inhibiting the nitrification of ammonium nitrogen consists of 1H-1,2,4-triazole being optionally substituted with guanyl or hydroxymethyl, their chlorohydrogenated or alkali salts or iron, copper or manganese based metal complexes and optionally substituted 3-methylpyrazole, chlorohydrogenated or alkaline earth salts or zinc and magnesium based metal complexes and/or at least one compound being selected from the group comprising dicyanodiamide, guanylthiourea, thiourea, ammonium rhodanide, and ammonium thiosulfate. Mixing ratio of two components ranges within 0.5 : 99.5 and 99.5 : 0.5 and mixing ratio of more than two components is arbitrary. |
