文摘

Nitrous oxide emissions and emission factors were determined. Emission factors determined were lower than the IPCC default value. Soil CH4-C uptake had a significant role offsetting N2O emissions. Only the use of NBPT significantly increased crop yield and N use efficiency, while only DCD reduced N2O emissions.
