New nitrification inhibitors and the use of polyacids to treat mineral fertilisers containing a nitrification inhibitor

摘要

The use of inorganic or organic polyacids to treat mineral fertilisers, in particular the use of polyacids as a mixture with at least one nitrification inhibitor to treat mineral fertilisers. The invention also concerns the use of selected pyrazole derivatives as inhibitors in mineral fertilisers and as stabilisers for liquid manure or liquid fertiliser 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 stabilisers in liquid manure or liquid fertiliser formulations.
