Resumen
The rice paddy is responsible for 12-16% of the anthropogenic emission of CH4 in the
world. Brazil is one of most important rice paddy producer. The goal of this study is to
understand the dynamics of methane exchange between rice paddy and the atmosphere in
the south of Brazil. Two estimation techniques are used: eddy covariance and soil chamber.
Data were obtained in a rice paddy farm in Cachoeira do Sul municipality. The total emission
of methane in 2015-2016 rice paddy growing season (November 14, 2015 to April 16
2016) was 35.7 gCH4m−2. The solar radiation is the weather forcing that showed a higher
correlation with methane emissions.
