Özet
The size distribution is an indication of the extent to which the soil is affected and its susceptibility to wind erosion, and the clusters with diameters less than (0.84 m) are among the most affected by wind erosion. In other words, the soil loss by wind erosion decreases with the increase in the size distribution of minutes and according to the following order: (clay 'silt, sand Which means that the sandy soil particles are less coherent than the clay soil particles, so soil aggregates with a high sand ratio are prone to separating more quickly than those with high clay content and thus have less resistance to wind erosion, unlike the clay agglomerations most affected by wind erosion. In other words, wind erosion of soil increases in sandy tissue soils, and the study reached the following results : -Wind erosion of soil increases in sandy textured soils if it ranges between (121 - 331) Mg, H - 1. As for the muddy sand textured, the values of the soil erosibility index decreased to (5 - 75) μg, H-1. -The results confirmed that the highest value of the soil erosibility index was in soils with low moisture content and ranged between (221.3 - 331.2) Mg, HAs for soils with low content of organic matter, it led to a high index of soil erosion vulnerability. -The highest value of the soil erosibility index was in soils, the higher the calcium carbonate content.

Abstract
The size distribution is an indication of the extent to which the soil is affected and its susceptibility to wind erosion, and the clusters with diameters less than (0.84 m) are among the most affected by wind erosion. In other words, the soil loss by wind erosion decreases with the increase in the size distribution of minutes and according to the following order: (clay 'silt, sand Which means that the sandy soil particles are less coherent than the clay soil particles, so soil aggregates with a high sand ratio are prone to separating more quickly than those with high clay content and thus have less resistance to wind erosion, unlike the clay agglomerations most affected by wind erosion. In other words, wind erosion of soil increases in sandy tissue soils, and the study reached the following results : -Wind erosion of soil increases in sandy textured soils if it ranges between (121 - 331) Mg, H - 1. As for the muddy sand textured, the values of the soil erosibility index decreased to (5 - 75) μg, H-1. -The results confirmed that the highest value of the soil erosibility index was in soils with low moisture content and ranged between (221.3 - 331.2) Mg, HAs for soils with low content of organic matter, it led to a high index of soil erosion vulnerability. -The highest value of the soil erosibility index was in soils, the higher the calcium carbonate content.
