Is indirect N2O emission a significant contributor to the agricultural greenhouse gas budget? A case study of a rice paddy-dominated agricultural watershed in eastern China

Characteristics of a rice-paddy-dominated agricultural watershed in eastern China. The run-off N generated from uplands can be intercepted by paddy fields below. And the lack of liquidity in water bodies result in the decrease of the redox potential, which may result in low ratio of N2O/N2 via denitrification.203
