Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere. Dinitrogen gas (N2) is the ultimate end product of denitrification, but other intermediate gaseous forms of nitrogen exist (Figure 7).
Nitrogen fixation - produces ammonia, denitrification - produces molecular N2 through intermediate gaseous nitrogen oxide products, Nitrification - biology oxidation of ammonia or ammonium to nitrite, Putrefying bacteria, assimilation - this is where plants incorporate NO3- and ammonia formed through nitrogen fixation and nitrification and take up ...
