Web30 de jan. de 2015 · Nitrification is a fundamental step in the N cycle, converting reduced N to oxidized N pools. Variation of nitrification with N fertilizer in agroecosystems is related to agronomic N-use efficiency (NUE) and environmental/human health problems [ 10, 11, 12 ]. WebAnammox would constitute a shortcut in the conventional N cycle, in which nitrification and denitrification are linked at the level of nitrite, without going through nitrate. Therefore, natural environments where ammonium and nitrite both occur in the presence of low oxygen concentrations might be suitable habitats for anammox-like reactions. nerf couteauWebAbstract.
