Abstract
The purpose. To study influence of irrigating by waters of different quality on directedness of edaphic processes and conversion of properties of typical black earth of Northern Steppe. Methods. Field, analytical, statistical. Results. Trends and directions are fixed of changes in physical, physical and chemical, chemical properties of typical black earth at irrigating by suitable, restrictedly suitable and unsuitable waters which consist in change of salt, mineralogical, granulometric composition, content of the absorbed cations, content of humus. Conclusions. With decrease of quality of irrigating water there is magnification of salinization, alcalination, seal, charging of granulometric composition, lowering of resistance of microscopic structure and content of water-resisting assembly units. That requires supervisory control of their properties for the warning of aggravation of soil-meliorative state and development of degradation processes.

Key words: typical black earth, salinization, alcalination, irrigating, conversion, irrigating water, properties.
