Wind can blow away the top soil, which is the most important part of the ground. The top soil has 3x the nutrients of the ground below it. The microbes, who process elements so they’re fit for plant consumption, live in this portion of the top portion of the soil. If organic matter is either blown away by the wind or exposed to the sun or water (another cause of erosion) then the ground can’t hold water, can’t convert minerals or fix nitrogen, and desertification begins. Some steps to prevent erosion include mulching and designing your garden or farm so it’s protected by windbreakers. These windbreakers can be trees, high hedges, fences, buildings.
