Anti-deflation stability at the soils of Steppe in Ukraine at depends on content elemental soil particles.

The article presents the results of the study of the index of anti-deflation stability at the soils of Steppe in Ukraine at depending on the content of elemental soil particles (ESP). It was found that when the content of ESP (up to 10-12%) is the highest, the index of anti-deflation stability of chernozems and dark chestnut soils is the highest (R2= 0,65), and when the content of ESP exceeds this limit, then the anti-deflation resistance of these the soil begins to decrease substantially. With employ a regression method we nominate three groups of soils for wind-resistant. On the first group, most wind-resistant been a load and average clay soils (VS>50%) with content organic matter 2,5-4,0%, to the second wind-resistant: light clay and sandy soils (VS 20-50%) with content organic matter 1,0-2,5%, to the third no wind-resistant coming a sandy soils (VS 0,7-20%) with content organic matter 0,5-1,5%.
