In the study area, aeolian processes have produced differences in surface soil textures across the region from southwest to northeast.
Surface soils are much sandier in Terry County than in Lubbock County.
As a result, Terry County had about four times greater wind erosion potential than Lubbock County. Cotton, unidentified cropland, and sunflower fields produced the greatest estimated amount of erosion in Terry County. Sunflower fields did not produce significant erosion in Lubbock County. Clearly, the map scale used in estimating erosion will have a profound impact upon the final estimate.
