The removal of topsoil by the natural forces is known as soil erosion. Causes of Soil Erosion Various agents, like wind, water, deforestation, overgrazing by cattle, etc., cause soil erosion. In some cases, sheet erosion washes away the top layer of soil in one continuous piece (one “sheet”). Or the force of water gives rise to the formation of small rills that can eventually develop into gullies.

There are ways to mitigate the 14 Sep 2020 The top layer of soil is often rich in nutrients and organic matter, making it important for growing food, fibres, feed and fuel.
Soil erosion decreases soil fertility, which can negatively affect crop yields. T value = Tolerable erosion equilibrium between soil gains and losses.” continuous cropping and maintain soil productivity without requiring additional management inputs.” • T ranges from: 1-5 t/ac/yr < 25 cm = 2.2 t/ha/yr > 152 cm = 11.2 t/ha/yr “Maximum soil erosion loss that is offset by the theoretical
Erosion comes in two forms: There’s degradation, which is a gradual erosion of the quality of the soil, and there’s loss of soil particles. Run-off from heavy spring or summer rainfall is not the only face of erosion — wind can just as easily blow soil particles down a slope. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.
