A. Soil erosion control

Accelerated soil erosion must be controlled. Because the nutrient reserves of most soils are mostly concentrated in the upper 10 to 15 cm layer of soil developed in situ (e.g., Oxisols, Ultisols, Alfisols), the loss of top soil has drastic impacts on productivity. Soil erosion control is the most important attribute of an ecologically compatible and productive land-use system.
