Interpretive Summary: Most wind erosion control measures are designed with some form of vegetative surface cover. These systems may employ shelterbelts, strip cropping, growing crops, and crop residues in various combinations or alone. This presentation will discuss examples of how these vegetative control measures impact the wind energy near the soil surface and how that alteration affects the amount of soil movement by wind. Technical Abstract: Wind erosion remains a serious problem in many parts of the world. Maintaining adequate vegetative cover on the land is an effective way to control wind erosion. Conservation practices based on vegetation include field windbreaks, annual crop barrier strips, strip cropping, stubble mulching, cover crops, regrassing and reforestation. cross wind trap strips, and controlled grazing. All vegetative practices reduce wind erosion by reducing the speed of the wind at the soil surface, by reducing the length of the field exposed to the full force of the wind, and/or by trapping particles that are moving. |
