WebDenitrification is the process during which the nitrogen compound is released back into the atmosphere by converting nitrate (NO3-) into gaseous nitrogen. What is nitrification? The fixing of atmospheric nitrogen in the form of nitrites and nitrates by microorganisms is called nitrogen fixation. Nitrification inhibitors are chemical compounds that slow the nitrification of ammonia, ammonium-containing, or urea-containing fertilizers, which are applied to soil as fertilizers. These inhibitors can help reduce losses of nitrogen in soil that would otherwise be used by crops.
