More specifically, it focuses on rill and inter-rill erosion and is not easily applied to areas where gully and stream bank erosion are widespread. Lateritic soils have low agricultural potentiality. The pH of a good soil should be about 7 but due to industrial effluents the pH increases or decreases causing pollution in soil.
Almost invariably, however, it is those ecosystems, in equilibrium with their environment, which offer most effective protection to the soil that supports them. Soil is disturbed by tillage operations and by the trampling of people and livestock.
