Growing crops that produce a large amount of crop residues and using conservation tillage can result in larger soil aggregates than when conventional practices are followed. Producing a crop in a ridged field will reduce wind erosion. The ratio of ridge height to distance between the ridges is very important. For example, to be most effective the ridge should be at least 2 inches high if the distance between the ridges is 8 inches. The ridge is usually formed with a tillage tool before planting or during cultivation of the crop in the growing season.
Dry climates are more subject to wind erosion than humid climates.
High wind velocity contributes to increasing wind erosion. Soil flow across a field is directly related to the width of the unprotected area and may be likened to an avalanche moving down a mountain. Soil flow or erosion increases with distance until the wind becomes saturated or is carrying its maximum load. The more erodible the soil surface, the shorter the distance at which maximum flow occurs and the narrower the fields must be to keep the soil loss at a tolerable level. Therefore, an effective means of wind erosion control is to reduce field width.
