| Research Abstract |
This study is conducted to try to find practical water management on paddy fields by farmers for reduction of greenhouse gas emission. Assuming that underdrain systems are available, the effect of changes in percolation patterns and percolation rates by manipulation of the groundwater level on the methane emission from paddy soil was investigated. It was revealed that the methane emission was considerably low when the water percolates in an open system and that there was a strong negative correlation between the percolation rate and the methane emission.
