BLACK SOILS DEGRADATION IN THE SOUTH-WESTERN BLACK SEA REGION AT IRRIGATION AND IN THE POST-IRRIGATION PERIOD

Abstract

Many years’ studies of process of changes in composition, properties and fertility of the black soils of the North-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 soils under irrigation conditions are worsening significantly.
