Aerobic denitrification is the main process for high N₂O production in acid tea field soil. However, the biological mechanisms for the high emission are not fully understood. In this study, we examined N₂O emission and denitrifier communities in 100-year-old tea soils with four pH levels (3.71, 5.11...
