Atmospheric nitrogen and proteins are not readily available as a source of nitrogen by … WebMay 11, 2024 · Nitrate is the form most living plants use to absorb nitrogen. Denitrification: Denitrification follows the process of nitrification and is where nitrates are returned to the atmosphere as nitrogen gas by denitrifying bacteria in soils [6]. Denitrification generally occurs in anoxic environments with exhausted oxygen levels. WebMar 5, 2024 · The two nitrogen atoms in a molecule of nitrogen gas are held together by a very stable triple bond. This bond must be broken for the nitrogen to be used. The nitrogen gas must be changed to a form called nitrates, which plants can absorb through their roots. The process of changing nitrogen gas to nitrates is called nitrogen fixation.
