This study was conducted to estimate the upland soil loss and canopy cover subfactor for revised universal soil loss equation (RUSLE) on different soil types using a slope lysimeter. The lysimeters were installed with 13% steepness, 25 m length, 2 m width under three different soil textures which were clay loam (CL), loam (L), and sandy loam (SL). The experiment was done for five months from 27-May to 29-October, 2020 and the soybean seedling was transplanted on 27-May and harvested on 29-October. Upland soil loss and runoff, soybean growth response, and meteorological data were monitored. Total eight times rainfall events recorded 710.5 mm precipitation, resulting in rainfall intensity (EI<SUB>30</SUB>) of 3,351.6 MJ mm ha<SUP>-1</SUP> hr<SUP>-1</SUP>. Total amounts of soil loss from uncultivated and soybean cultivated soils were 31.8 and 6.9 ton ha<SUP>-1</SUP> for CL, 32.3 and 16.8 ton ha<SUP>-1</SUP> for L lysimeter, 61.04 and 14.4 ton ha<SUP>-1</SUP> for SL, respectively. In addition, the canopy cover subfactor of RUSLE values for CL, L, and SL were 0.564, 0.507, and 0.371, respectively. The highest soil loss was measured at 18 days after soybean transplanting (DAT18), occupied 75% of total soil loss over whole experiment period.
