Soil erosion reduced by diverse eco-agricultural systems in South China.
Soil erosion was studied in South China under different farming methods. The amount of soil loss varied between forest, agro-forest, crop, and crop and engineering systems. Soil erosion was highest at 15° slope compared to 10° slope. Early stages of farming systems had more erosion, but it decreased over time. Vegetation cover, slope, and farming frequency affected soil erosion. Complex farming systems had less soil and water loss than single-crop systems. The type of plants and community structure influenced soil and water conservation efforts.
