Many years studies of process of changes in composition, properties and fertility of the black soils of the Norh-Western Black Sea area in Ukraine with irrigation have revealed mobility of carbonates and humus in them, decrease of capacity of cationic consumption and content of consumed calcium, increase of share of consumed magnesium and sodium. Indicators of agro-physical state of sails under irrigation conditions are worsening significantly. In the last 15-20 years, due to sharp decrease in area of irrigated fields an extensification of agriculture the display of agrophysical solonetzicity of previously irrigated lands is strengthening, as well as processes of their dehumification: indicators of ecological&agrochemical state are degrading. Substantiated is the system or ago-amelioration measures aimed to prevent from degradation processes of irrigated black soil missives and increase their fertility.
