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).
Denitrification is the biological process in which nitrate is converted to atmospheric N2. 1  It is one source of N loss from the soil. 2  Like other N processes, denitrification is a biological process that is mediated by denitrifying bacteria. 3  Waterlogged soils: In waterlogged soils, the flow of air is poor.
