FIELD: agrochemistry.

SUBSTANCE: present invention relates to agrochemistry, namely to use of novel nitrification inhibitors of formula (I), which are N-functionalised alkoxypyrazole compounds. Disclosed is the use of an N-functionalised alkoxypyrazole compound of formula I

(I)

or a salt thereof as a nitrification inhibitor, where R¹ is C₁-C₂-alkyl or benzyl; R² is C₁-alkyl; R^N is CHR^aOR^b 1 and where R^a is H; R^b is H; n is 0 or 1. Use of a composition for reducing nitrification containing at least one compound of formula I and at least one carrier. Agrochemical mixture containing at least one fertilizer and at least one compound of formula I. Method of reducing nitrification. Method of treating fertilizer or composition for reducing nitrification.

EFFECT: disclosed group of inventions provides the use of N-functionalised alkoxypyrazole compounds of formula I as nitrification inhibitors, which have high activity, have low volatility and toxicity.
