differentiate between soil erosion and soil exhaustion ?
Soil Erosion - Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage.
Soil Exhaustion - Soil exhaustion occurs when poorly managed soils are no longer able to support crops or other plant life. Soil exhaustion has consequences beyond limited food production; it also increases risk of soil erosion. Proper soil management -- including crop rotation, fertilizer applications and irrigation methods -- helps decrease the potential for soil exhaustion.
