Bare, unprotected soil is extremely vulnerable to wind erosion. Erosion occurs with strong, turbulent winds blowing across a soil surface that is smooth, loose, dry and finely granulated. Very fine particles are suspended in the air stream and carried long distances. Slightly larger soil particles bounce or roll along the soil surface. Loose particles drift along, bombarding and dislodging still more particles with the same effect on clods or growing plants as sandblasting.
