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 ... WebNitrogen compounds and potential environmental impacts Agriculture may be responsible for about half the nitrogen fixation on Earth through fertilisers and the cultivation of nitrogen-fixing crops. Increased nitrogen inputs (into the soil) have led to lots more food being produced to feed more people – known as ‘the green revolution’.
