Cryostructurization of top soil with aqueous polymer solution has been demonstrated to result in the increase of the part of coarse fractions and the amount of water-stable aggregates in aggregate composition; the angle of the natural soil slope increases from 7 to 45°. All this suggests increased resistance of cryostructured soil to wind and water erosion. In addition, cryostructurization improves the plant growth, increases the number of microorganisms, and promotes accumulation of humic substances in the soil.
