Soils in agricultural lands contain large amount of organic matter and nutrients due to the injected fertilizers and manure. During heavy rain, surfacewater and base runoff pollutants flows into a nearby stream or lake with eroded soil from agricultural lands. On the other hands, agricultural landsnear the lake are inundated due to the increase of the water level in the lake, leading to organic matter and nutrient release from the inundated soil. In this study, releasing rates of nutrient salts and organic substances were analyzed for the soil in the agricultural land, where cultivation activities hasbeen carried out and periodically flooded, to account for the possibility of contamination from the inundated agricultural land in reservoir areas Theexperiment results have shown that COD was released from the soil in anaerobic conditions, and T-P was released in both anaerobic and aerobicconditions. However, in the case of T-N, it was found that the runoff by soil was not made before the rainfall occurred, and when the soil was impounddue to rainfall, the elution occurred under the aerobic conditions. Through the results of this study, it was possible to account for the effect of floodedagricultural lands on the water quality in the lake, and this could be reflected in an efficient agricultural non-point pollution management policy. Inorder to determine the precise releasing rate for each agricultural land, it is believed that the leaching experiment for paddy fields and grasslands areneeded.
