Wind erosion is a serious ecological problem, which occurs in flat, bare areas, dry and sandy soil, wherever the soil is loose and finely granulated. Win erosion destroys the vegetation by removing the land needed for the plants, and depositing it elsewhere. The speed of the wind needed for erosion varies from the site and the construction of the soil. Although erosion is possible at any height, percentage, the highest erosion rate of 93% occurs on land that is at a height below one meter. The most effective protection against wind erosion is surface texture, as well as proper management of crop residues, carefully selected soil treatment that will not contribute to erosion, crop strips, and barriers. Of course, the most effective is surface texture that is is planting plants, trees.
The answer is: A.
