Nitrous oxide production in wetlands

FIGURE 16.6 Zones of nitrification-denitrification reactions in continuously flooded wetland soils. 

In wetlands, N2O production via denitrification and subsequent emission is governed by the oxygen status of the sediment, supply of nitrifiable nitrogen, moisture content, and temperature. Since the denitrification pathway requires anaerobic conditions, a low partial oxygen pressure during the denitrification process enhances the formation of NjO.
