denitrification

the process by which nitrogenous compounds are degraded and nitrogen is returned to the air in gaseous form, e.g. the breaking down of nitrates and nitrites to gaseous nitrogen, carried out in the absence of oxygen by soil bacteria. The process is associated with waterlogged soils and low fertility. See NITROGEN CYCLE.
