Effect of soil crusting on soil wind erosion

Soil crusting is a self-protection of the soil to resist wind erosion, which can stabilize the soil and greatly enhance the resistance of ground soil against wind erosion, so it calls more and more attention to the uncultivated and deserted areas. There are two kinds of soil crusts: physical soil crust and biological soil crust. The production of the latter needs a long time, while the former comes into being easily after a drying and wetting process. This paper studies the relationship between the formation of physical soil crust and the percentage of water in the soil, the composition of soil particles in the light of the analysis after the observation on the spot to the samples of soil crust of the original state from different soil, and observes them with electronic microscope, the paper also gives a detailed account of soil's anti-erosion, so that they can be paid adequate attention to prevent the soil desertification in the dry and cold areas, and to reduce the soil crusting and lessen the damage of wind erosion to the ground soil in winter and spring.
