Abstract

A method for suppressing soil nitrification, characterized by the use of one or more compounds that fall into the following general groups: a) trichloromethyl-pyridines and their salts; b) R-nitroso compounds with the general formula ** (See formula) ** where A is methyl, ethyl, phenyl, tolyl or chlorophenyl if B is methyl or ethyl or A and B are interconnected to form with the basic nitrogen atom a ring of 1-piperidyl, 1-pyrrolidyl, 4-morpholinyl, 3-pyrroline or hexamethyleneimine; c) tertiary alkynes that have the structure ** (See formula) ** where R is hydrogen or methyl, R1 is an alkyl radical having from 1 to 9 carbon atoms and R2 is an alkyl radical having from 1 to 4 carbon atoms; d) a halophenol compound or its salts with the general formula ** (See formula) ** where X and Y are each chlorine or bromine and the second Y is hydrogen; e) a Haloanilide with the formula ** (See formula) ** where X is halogen, n is 1 or 2 and R is an acyl radical derived from a monocarboxylic acid having a molecular weight of 46 to 300 and containing only the carbon, nitrogen and oxygen elements in its structure; f) halcanilines or their salts with the general formula ** (See formula) ** wherein X is hydrogen, methyl, chloro, bromo, or fluoro, Y is fluorine, chlorine or bromine and R is an amino, dimethylamino, lower alkylamino or alkynylamino group; g) aminopyridine or its salt with the general formula ** (See formula) ** where X is hydrogen or methyl and Y is hydrogen, chlorine or bromine; h) a haloalkane having 2 to 3 carbon atoms and 5 to 8 chlorine and/or bromine atoms.
