Comparison of Carbon Dioxide (CO2) Fluxes between Conventional and Conserved Irrigated Rice Paddy Fields in Myanmar
Original language description
Rice (Oryza sativa. L.), a major food crop widely grown in Myanmar, is the most prominent cause of greenhouse gas (GHG) emissions in agriculture. Moreover, as a result of modification in agricultural management practices (such as soil tillage), the soil organic matter is exposed to more oxidizing conditions, releasing CO(2)into the environment, contributing to global warming. Therefore, we studied the effects of both conventional and conservation soil tillage management practices on CO(2)fluxes on an experimental rice paddy field in Myanmar. Total CO(2)emissions during the night from paddies farmed under conventional practices were significantly higher than those from paddies farmed under conservation practices; however, no net CO(2)flux differences were found between practices. Total net CO(2)fluxes ranged from -59 to 1614 mg CO(2)m(-2)h(-1)in conventional practices and from -282 to 1082 mg CO(2)m(-2)h(-1)in conservation practices, respectively. Significantly higher rice biomass and grain yields were observed in conventional practices when compared to those in conservation practices, causing a significant rise in both CO(2)uptake and emissions during the day and night, respectively. In addition, the results of this study revealed that CO(2)emissions in rice fields could be much higher than expected, requiring further study to elucidate key factors driving the dynamics of CO(2)in rice paddy systems.
