Certain metal salts of certain substituted pyrazole compounds are employed as the active nitrification inhibitor in the presence of reduced nitrogen fertilizers. Compositions containing these salts can be applied to the surface of soil and can remain on said soil surface for up to 3 days or more without incorporation into the soil and retain at least about 70 percent of the pyrazole in the salt in the composition.
The use of inorganic or organic polyacids for the treatment of inorganic fertilizers, in particular the use of the polyacids as a mixture with at least one nitrification inhibitor for the treatment of inorganic fertilizers; the use of selected pyrazole derivatives as nitrification inhibitor in inorganic fertilizers and also as stabilizers of liquid manure or liquid fertilizer formulations, as well as the corresponding treated inorganic fertilizers per se; and novel pyrazole derivatives which can be used as nitrification inhibitors in inorganic fertilizers and also as stabilizers of liquid manure or liquid fertilizer formulations are described.
