Overestimation of N2O mitigation potential by water management in rice paddy fields [Biological Sciences]

In PNAS, Kritee et al. (1) report extremely high nitrous oxide (N2O) fluxes from rice paddy fields with intermittent irrigation and alternate wetting and drying (AWD) and conclude that N2O can be reduced by up to 90%—with nitrogen management not playing a central role. However, we believe that this conclusion...
