The linkage between intrinsic differences in the denitrifying communities and pH effects on relative N2O production was also assessed. Soil pH values were adjusted just before DEA determination to obtain soil slurries with a range of pH values. The intrinsic differences in the denitrifier communities were assessed by measuring the kinetic constants of NO3- and N2O reductions. DEA for all three soils was highest at pH 8.4, regardless of native soil pH. Because DEA has typically been measured at native soil pH, our results suggest that DEA might have been underestimated in many previous studies.
