- Abstract
The article presents research into empirical modeling of soil chemistry regarding atmospheric methane production in rice paddies. Measurements of carbon dioxide, methane and iron content in Japanese rice paddy samples were taken and analyzed concerning their role as indicators of iron reduction and organic matter decomposition processes. A resulting simulation model for methane production is given, determined through a derived relationship between total and reduced iron content found in the sample soils.
