In continuously waterlogged soils, complete denitrification to N\u2082 tends to dominate, making these environments N\u2082O sinks or negligible sources. In partially drained or fluctuating water table wetlands, incomplete denitrification and active nitrification in oxic surface layers combine to produce significant N\u2082O emissions.<\/p>\n<div class=\"atmo-data-box\">\n<div class=\"atmo-data-box__title\">Wetland N\u2082O Fluxes<\/div>\n<p>Permanently flooded: often near-zero or negative<br \/>\nSeasonally flooded: 0.1\u20132.5 mg N\u2082O-N\/m\u00b2\/day<br \/>\nDrained peatlands: 1\u201310+ mg N\u2082O-N\/m\u00b2\/day<br \/>\nRewetted peatlands: variable, often decreasing<\/div>\n<h2>Peatland Drainage<\/h2>\n<p>When peatlands are drained for agriculture \u2014 as has occurred extensively in Southeast Asia, Europe, and North America \u2014 N\u2082O emissions increase dramatically.
