Aim. The study of direct (wind erosion resistance) and indirect (lumpiness, mechanical durability, etc) indices of current wind erosion resistance of steppe soils in Ukraine. Methods. The following methods were used: fi eld, laboratory, mathematical and statistical, analytical and comparative methods. Wind resistance of soils was studied using the elaborated method in the aerodynamic unit. Results. The studies revealed that the high- est resistance to soil blowing due to strong winds is demonstrated by light loamy chernozem, somewhat lower resistance – by southern and dark-chestnut heavy loamy chernozem, light loamy, sandy loamy and sandy turf soil. It was demonstrated that the irrigation with mineralized water enhances the indices of wind erosion resis- tance of dark-chestnut soil and southern chernozem. The granulometric analysis of soil revealed quantitative dependence between the wind erosion resistance, humus content and physical clay content. Conclusions. The studies on wind erosion resistance of dry steppe and southern steppe soils of Ukraine and the classifi cation of soil types regarding their capability of resisting strong winds allow implementing the measures of preventing wind erosion.
