Measurement of methane emission from rice production systems is a methodology for data collection of Carbon Footprint from rice production system. Four major rice production systems were defined for methane emission measurement in 2012, including upland rice, rainfed rice, irrigated rice with good agricultural practices (GAP) and irrigated rice with alternative wet and dry (AWD). Gas samples were taken one week interval and analyzed by Gas Chromatograph; GC-8A as soon as possible after collection. The research found that upland rice could absorb CH4 at the rate of 0.176 kg methane rai-1 season-1. Rainfed rice production system in Northeast Thailand emitted CH4 at the rate of 85.26 kg rai-1 season-1 under transplanting and 51.64 kg rai-1 season-1 under...
