Along with the extension of rotational paddy filed through subsurface irrigation system, estimating carbon and nitrogen dynamics in the paddy soils is getting important. We perform several column experiments to investigate change in redox potential in soil with solute and water flow. The change in redox potential was summarized based on the flow rate and solute concentration. For the evaporation process, the response time and changing rate of soil redox potential against the air penetration were clarified.

随着地下灌溉系统轮作稻田的推广，估算稻田土壤中的碳和氮动态变得越来越重要。我们进行了几次柱实验来研究土壤中溶质和水流氧化还原电位的变化。根据流速和溶质浓度总结氧化还原电位的变化。对于蒸发过程，明确了土壤氧化还原电位对空气渗透的响应时间和变化率。
