Since the Dust Bowl, conservation methods have helped protect topsoil from being lost to wind erosion.

On North America's Great Plains region during periods of drought, wind erosion moves 6,000 times more soil than during periods of greater rainfall. This shows that the roots of live plants are the best way to hold soil in place.

Conservation efforts include growing vegetative barriers that deflect wind currents and plowing ridges in fields prone to wind erosion. Farmers can also plant fall crops, such as wheat or rye, after beans, potatoes, and sugar beets have been harvested. Covering the surface of the ground with leftover crop cuttings is another effective method that reduces wind erosion.
