Nitrous Oxide Emissions from a Subtropical Agricultural Field

Abstract:

N2O emissions have been increasing in recent years due to intensive agricultural practices. This study was conducted to evaluate N2O emissions from a subtropical paddy field of south China with closed static chamber and a gas chromatograph in situ in the second crop season. Gas samples were taken simultaneously from rice-involved and rice-free plots. It showed that diurnal variation of N2O emission was more regular at the booting stage. The diurnal mean N2O flux of rice-involved plot was higher than that of rice-free plot during flooding time but lower during the drying time. It showed no significant correlation between N2O flux and temperature. The N2O flux was affected by soil water regime. Rice paddy field in growing season is a N2O source to atmosphere.
