Soil deflation in Ukraine

Annotation Purpose. To determine the parameters of the potential danger of soil deflation on the territory of Ukraine as a theoretical basis of investment policy for the formation of anti-deflation protection. Methods. General scientific (field, morphological-genetic, mathematical and physical modeling of processes of blowing (deflation) of soil milky soil and cartographic with rinsing of GIS-technologies. Results. Based on the physical modeling of wind erosion in the wind tunnel, the epic equation of potential deflation of the main soils of Ukraine is formed. The map of the maximum blowing of soil fine soil of 20 % of security is created. The unit of measurement was the area of the administrative district, the GIS technology of the software product “Relief Processor”, transferred to one of the authors Boris Vorobyov, was used. Regions with a catastrophic risk of deflation are in Polissya and the Southern Steppe. At the same time, 30 years ago, deflation was not heard of in Polissya. Conclusions 1. Without a radical change in the principles of land use and agricultural syste ms, the revival of landscapes and agricultural lands in regions with a high risk of soil deflation is impossible 2. Quantitative assessment of the potential danger of blowing small soils is a necessary condition for justifying anti-inflationary measures. 3. On the basis of the empirical model of deflation of NSC “IGA” zoning of arable lands of Ukraine on the danger of soil deflation is made. One of the main tasks of further research of deflation processes is to develop models that reflect the physics of soil blowing and have a sufficient mathematical basis. 4. The basis for the formation of anti-erosion strategy and appropriate investment policy is a quantitative assessment of the potential danger of deflation. The higher the danger, the more reliable the protection should be, first of all, these are measures of permanent action that require appropriate capital investment. In addition, there is a need to create a network of monitoring observations of deflationary processes and their factors. Keywords: deflation, danger of deflation, anti-deflation protection.
