Nitric oxide emissions from drylands

Based on measurements of dryland soils near Santa Barbara, California, researchers report that the dry season limits the amount of nitrogen plants sequester and allows nitrogen to accumulate in soils, but at the onset of the wet season, dryland soils emit a pulse of nitric oxide, a regulator of atmospheric photochemistry, likely through abiotic mechanisms and microbial pathways, suggesting that intensification of droughts and increase in nitrogen deposition could increase nitric oxide outputs from drylands. - Read at PNAS.org
