How does soil erosion impact soil health?

Soil erosion significantly impacts soil health primarily by leading to the loss of soil fertility. When soil is eroded, the top layer—rich in organic matter and nutrients—is often removed. This topsoil is crucial for supporting plant growth, as it contains essential nutrients, microorganisms, and organic matter that contribute to soil fertility. The removal of this layer can result in poorer soil structure, decreased water retention, and lower overall productivity. Consequently, as fertility decreases, the ability of the soil to support healthy plant life diminishes, which can lead to further erosion and degradation in a compounding cycle. Understanding this relationship is vital for soil conservation efforts and maintaining healthy ecosystems.
