Because soil degradation contributes to land degradation, it also means that it creates a significant loss of arable land. Most agricultural practices involving the use of fertilizers and pesticides often entail misuse or excessive application, thereby contributing to the killing of soil’s beneficial bacteria and other micro-organisms that help in soil formation. All these physical factors produces different types of soil erosion (mainly water and wind erosion) and soil detachment actions, and their resultant physical forces eventually changes the composition and structure of the soil by wearing away the soil’s top layer as well as organic matter. These organisms interact with one another and with plants and small animals forming a web of biological activity. Soil pollution refers to the contamination of soil with anomalous concentrations of toxic substances. The complex forms of the fertilizer’s chemicals are also responsible for denaturing essential soil minerals, giving rise to nutrient losses from the soil. Soil degradation examples include decline in soil fertility, adverse changes in alkalinity, acidity or salinity, extreme flooding, use of toxic soil pollutants, erosion, and deterioration of the soil’s structural condition. Most of the soil eroded from the land together with the chemical fertilizers and pesticides utilized in agricultural fields are discharged into waterways and streams. Generally, the most important factor that determines healthy or good quality soil is organic matter.
