Bioremediation of nitrate-contaminated shallow soils and waters via water table management techniques: evolution and release of nitrous oxide


Nitrate (NO3±N) commonly accumulates in soils because of fertilizer additions or when crop demand is much less than the rate of NO3±N production. Water table management (WTM) has been proposed to stimulate denitrifying bacteria, thus removing the accumulated NO3±N by converting it to N2O (a greenhouse gas) and N2. We studied the emission of N2O and N2 as a… (More)
