Abstract

This study aims to determine the relationship between Organic C and soil texture on the erosion rate in agroforestry land use. This research was conducted from February to May 2025 in three locations: West Angkola, South Angkola, and East Angkola in Tapanuli Tengah Regency with three samples at each location. Data analysis was performed using USLE (Universal Soil Loss Equation) and simple linear regression (SPSS). This research shows that the results of regression analysis indicate that the correlation coefficient of Organic C to the erosion rate is 0.780 (very weak), the correlation coefficient of soil pH to the erosion rate is 0.372 (very weak), the correlation coefficient of sand to the erosion rate is 0.698 (very weak), the correlation coefficient of silt to the erosion rate is 0.318 (very weak), the correlation coefficient of clay to the erosion rate is 0.526 (very weak). This means that the higher the Presence Of :Organic C and soil texture in the soil, the rate of erosion will increase.
