Abstract
Changes in the soil physical property and the topographic condition derived fromagricultural activities like as farming activities, land clearance and cutting down resulted inenvironmental and economic problems including the outflow of nutrient from farms and thewater pollution. Several theories on the soil conservation have been developed and reviewed toprotect soil erosion in the regions having a high risk of erosion. This study was done using thesteepness made by Desmet and Govers (1996), and Nearing (1997) to evaluate the potential ofthe soil erodibility. Therefore, several results were obtained as follows.First, factors affecting the soil erosion based on the USLE could be extracted to examine theerosion potential in farms. Soil erodibility (K), slope length (L), and slope steepness (S) wereused as main factors in the USLE in consideration of the soil, not by the land use or land cover.Corresponding Author: Jang, Gab-Sue, Dept. of Environmental and Ecological Research, Chungnam Development Institute, 138-42 SangDae-Dong, YuSeong-Gu, DaeJeon 305-313, Korea Tel: 82-42-820-1182 Fax: 82-42-820-1129 E-mail: janggs@cdi.re.kr
