Abstract
Assessment of irrigation properties of the surface waters within the boundaries of the Dniester and Bug interstream area of the Odessa region (basins of the rivers Baraboy, Small Kuyalnik, Large Kuyalnik and Tiligul) according to agronomic criteria in 2011…2015 has been made. Agronomic criteria include evaluation of water quality according to the hazard of irrigation salinity, alkalinity, and alkalinity of soils and toxic effects of irrigation water to the plants. Additionally, assessment of water quality according to the hazard of alkalinity and alkalinity of soils on the thermodynamic parameters has been conducted. Three classes of water suitability are defined: «suitable», «limited usefulness» and «unsuitable» for irrigation of soils of different categories. The research has shown that the agronomic criteria of surface water are mainly characterized by low irrigation properties, correspond to classes II and III of water quality and are rated as «partially suitable» and «unsuitable» for irrigation. The effects of soil irrigation in the organization of irrigation with substandard irrigation water are considered. In order to prevent negative processes in soil formation and soil conservation, the paper covers the main physical and chemical methods to improve the water quality before applying it to the field (dilution to safe concentrations, acidification and making calcium improver).
