WebJul 5, 2013 · Global nitrogen fixation contributes 413 Tg of reactive nitrogen (N r) to terrestrial and marine ecosystems annually of which anthropogenic activities are responsible for half, 210 Tg N.The majority of the transformations of anthropogenic N r are on land (240 Tg N yr −1) within soils and vegetation where reduced N r contributes most of the input …
WebDenitrification is a biological process of reduction in which the nitrogen compounds are released back into the atmosphere in their gaseous form – nitrogen gas (N) by the conversion of nitrate (NO 3– ). Therefore, this is the final stage of the nitrogen cycle, carried on without oxygen. The entire process of denitrification is carried out ... WebJun 3, 2024 · Total N 2 fixation was twice as high in algae- compared to coral-dominated areas, whereas denitrification levels were similar. We conclude that algae-dominated reefs promote new nitrogen input through enhanced N 2 fixation and comparatively low denitrification. The subsequent increased nitrogen availability could support net …
