Regional and intensive rainfall pattern due to climate change has threatened the farming environment. While many structural and chemical countermeasures have been developed to reduce the damages of agricultural infrastructure, it was somewhat insufficient to consider site-specific and crop growth conditions. Therefore, this study adopted the soil enhancer(Polyacrylamide) developed in the early 1920s and applied to sloped areas in Korea to evaluate its effects to reduce soil erosion. Two factors, slope(10, 20, 30%) and usage dose(0, 20, 40kg/ha), were compared using nine lysimeters located in the National Soil Science, Rural Development Administration. The findings of this study were 1) as the usage dose of soil enhancer was increased, the amount of soil eroded was reduced(12.2~78.0% of reduction), 2) as the slope of fields was steeper, the amount of eroded soil was increased, however, the plots treated with soil conditioner obtained the desired results (35.9~56.6% of reduction). Further investigation, such as optimal dose determination, and applying period/method depending upon soil conditions, was also suggested in this study.
