Abstract: The use of anorganic or organic polyacids to treat mineral fertilizers, in particular the use of polyacids as a mixture with at least one nitrification inhibitor to treat mineral fertilizers. The invention also concerns the use of selected pyrazole derivatives as inhibitors in mineral fertilizers ans as stabilizers for liquid manure or liquid fertilizer formulations, and the treated mineral fertilizers themselves, as well as new pyrazole derivatives that can be used as nitrification inhibitors in mineral fertilizers and as stabilizers in liquid manure or liquid fertilizer formulations.

Abstract: The use of inorganic or organic poly acids is claimed for treating mineral fertilisers containing a nitrification inhibitor. The use of compounds of formula (I) is claimed as nitrification inhibitors. R1 = H, halo or 1-4C alkyl; R2 = 1-4C alkyl; R3 = H or CH2OH, and when R3 = H, the compound may be converted to a phosphoric acid salt. A mineral fertiliser containing a poly acid and optionally (I) is also claimed. 3,4-dimethylpyrazole (Ia), 4-chloro-3-methyl-pyrazole (Ib), N-hydroxymethyl-3,4-dimethylpyrazole (Ic), N-hydroxymethyl-4-chloro-3-methylpyrazole (Id), acid addition salts of (Ic) and (Id), and mixtures of two or more of (Ia)-(d) are new.
