Atmospheric methane concentration has been increasing at the rate of approximately 1% per year. How much of this increase is due to increased emissions from flooded rice fields is unknown but rice cultivation will continue to increase, raising the possibility of further methane emission increases. At the same time, irrigated rice is one of the few sources where management of methane emission is possible. This paper reviews several emission studies carried out by the authors over a 4 year period on three different soil types as well as new data. Evidence is presented that methane emission values in different soils can be compared by correlating them with soil texture quantified by the amount of sand present in the soil. Emission values were found to be characteristic of the soil type. 24 refs., 2 figs., 4 tabs.
