Methane and nitrous oxide emissions from rice paddy fields
Recent field studies in rice paddy fields in Japan and China have shown that N2O is emitted to the atmosphere not only after the application of nitrogen fertilisers under flooded conditions but also in a period from the final drainage to submergence in the following rice-growing season through nitrification or denitrification. Those results clearly indicate that CH4 and N2O emissions in rice pa...

متن کاملA two-year field measurement of methane and nitrous oxide fluxes from rice paddies under contrasting climate conditions
The effects of three irrigation levels (traditional normal amount of irrigation [NA100%], 70%, and 30% of the normal amount [NA70% and NA30%]) and two rice varieties (Oryza sativa L. Huayou14 and Hanyou8) on CH4 and N2O emissions were investigated over two years under contrasting climate conditions (a 'warm and dry' season in 2013 and a normal season in 2014). Hanyou8 was developed as a drought...
متن کاملCarbon dioxide and methane fluxes from an intermittently flooded paddy field
To assess the role of floodwater in controlling the exchanges of CO2 and CH4 from soil, floodwater and the canopy in intermittently flooded rice paddies, an intensive field campaign (IREX96) was conducted in Japan during August 1996. Eddy covariance was employed to measure fluxes of heat, water vapor and CO2. The flux-gradient method was used to determine CH4 fluxes from measured profiles of CH...
