Mittel zur Regulierung der Nitrifikation von Ammoniumstickstoff in Böden

摘要

The invention relates to novel agents for preventing or regulating the nitrification of ammonium nitrogens in arable ground. It is the purpose of the invention to improve the efficiency, durable action and volatility of the basic type of prior art nitrification inhibitors. It has astonishingly been found that agents which contain as active components metal salts corresponding to the general formula (I) in which M is NH4, alkaline and alkaline earth ions and preferably Ca and Mg, Fe and Al, R is hydrogen, halogen or methyl, X can include a monovalent inorganic anion, preferably halogen, m is usually zero but can be 1 or 2 in the case of alkaline earth or aluminium cations, and S may assume values between 1 and 3, have a better nitrification-preventing action and are less volatile.
