WebJul 23, 2024 · The processes of nitrification and denitrification produce a potent greenhouse gas called nitrous oxide (N 2 O). But about 40% of the N 2 0 in the atmosphere is due to human activities. For example, agriculture can result in more nitrogen in the soil. More nitrogen in the soil means more nitrification and denitrification. WebDenitrification is the last step in the nitrogen cycle. It is a naturally occurring, microbially mediated process, where nitrate is used as a form of energy for denitrifiers. In this process, soil bacteria convert plant-available soil nitrate (NO 3–) into nitrogen (N) gases that are lost from the soil. Denitrification produces several gases ...
