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 through forces associated with farming activities such as tillage.

Causes: The agents of soil erosion are water, wind, ice, and gravity. Running water is the leading cause of erosion. because water is abundant and has the power to erode the upper layers of the soil. The wind is also a leading cause of erosion as it can pick up and blow soil far away.

• Add mulch or rocks.
