Summary The influence of different O2 concentrations on denitrification was studied in an agricultural soil. In both nitrate and nitrite amended soil, denitrification was not observed until the O2 concentration decreased to 0.20 and 0.21 μmol/ml, respectively. Denitrification was not observed in soil samples with O2 concentrations above 0.28 μmol/ml in the gas phase. These findings suggest that a completely anoxic environment is not required for denitrification to occur in soil.
