Riparian wetlands located in agricultural catchments may often receive a high nitrate (NO3−) load because of the leaching of nutrients derived from upland farming activities. Nitrate can be removed in wetland soils by denitrification which is the reduction of NO3− to the gaseous forms nitrous oxide...
