Abstract: The article presents the results of perennial investigations in the field of causes of degradation and desertification of the irrigated soils of Southern Steppe of Ukraine, scientifically substantiated measures directed to decrease of degradation and reconstruction of the soils fertility. The methodological basis of the investigations is made up by the modern methods of scientific research: historical, system analysis and approach, economic, statistical, and graphical methods. The natural and anthropogenic factors of influence on the processes of degradation and desertification of the soils are determined. It was proved that one of the causes of degradation is their natural dryness, which is accompanied by lack of precipitation, negative water balance, and connected with it specific process of soil formation. The measures of the soil fertility conservation are substantiated. The example of practical use of the results of the investigations in State Enterprise Research Farm «Askaniiske» of the Institute of Irrigated Agriculture of the NAAS is given. The developed measures of the soils fertility conservation allow to prevent their degradation, provide the non-deficient balance of humus, increase the efficiency of agricultural activity on the irrigated lands, improve ecological state of agricultural landscapes, and solve an important state task of providing food safety as a component of the national safety of Ukraine.
