Soil Erosion
The process of removal of topsoil either naturally or by human activities is called soil erosion. Naturally, erosion of the soil is done mainly by running water and wind. It is a slow process, and the majority of the time goes unnoticed. The destruction of soil structure caused by human activity accounts for the removal of soil to a large extent. This type of accelerated soil erosion results in the declination of the fertility of the soil.
Soil Conservation
The protection of soil deterioration of quality and quantity is called soil conservation. It can be done through various ways such as preventing deforestation, controlled grazing, dam construction, contour farming, crop rotation, strip farming, cover cropping, reducing shifting cultivation, etc.
