Abstract (en)
[origin: DE4446194A1] Disclosed is the use as nitrification inhibitors of pyrazole derivatives of formula (I), or salts thereof, in which the groups R<1>-R<4> have the following meanings: R<1>, R<2> and R<3> represent C1-C20 alkyl, C3-C8 cycloalkyl, C5-C20 aryl or alkyl aryl (these four groups can be singly or doubly substituted by a halogen and/or hydroxyl), and halogen, nitro or hydrogen; and R<4> represents either (a) C6-C20 alkyl, one or two hydrogen atoms being optionally substituted by a halogen; or (b) C1-C20 alkyl. In the latter case, 1-4 hydrogen atoms can be substituted by a group of formula (II), in which R<5>, R<6>, and R<7> represent C1-C20 alkyl, C3-C8 cycloalkyl, C5-C20 aryl or alkyl aryl (these four groups can be singly or doubly substituted by a halogen and/or hydroxyl), as well as halogen, nitro or hydrogen; and 1 or two hydrogen atoms are optionally substituted by a halogen.
