Soil movement is initiated as a result of wind forces exerted against the surface of the ground. For each specific soil type and surface condition there is a minimum velocity required to move soil particles. This is called the threshold velocity. Once this velocity is reached, the quantity of soil moved is dependent upon the particle size, the cloddiness of particles, and wind velocity itself. Suspension , saltation , and surface creep are the three types of soil movement which occur during wind erosion.
Surface texture is the best key to wind erosion protection.
Properly managed crop residues , carefully timed soil tillage , and accurately placed crop strips and crop barriers can all effectively reduce wind erosion.
