Soil erosion is one of the world’s major environmental issues. Each year wind and water erode 75 billion tons of soil, most of it from agricultural land. Erosion is a natural process but is accelerated by practices such as land clearing, overgrazing and soil cultivation. It removes fertile topsoil that contains most of the soil’s plant nutrients and soil microorganisms that contribute to soil health. The subsoil that remains is less fertile.
