Wind erosion physically removes the lighter organic matter, clays, and silts. These are the most fertile part of the soil. How can the problem be helped? See how people are slowing downt he problem!
wind breaks – planting a row of trees & shrubs to slow wind
against the wind – planting crops in rows perpendicular to wind flow
cover it up! – using mulch or plants to cover exposed soil
