Dynamics of Restoration Processes in the Idle Solonetz Ecosystems in the Southern Transural Region

The initial period of idleness in the solonetz ecosystems of the southern Transural Region is characterized by a significant variability of their soil–plant communities, which is determined by natural periodicity and general direction of the process of ecosystem restoration. Selective consumption of salinizing ions by the plants growing on idle land activates the development of desalinization processes.     

Soil-ecological conditions of the zone of salt waste dumping and plant adaptation to them

Technogenic surface formations near salt waste dumps are subject to salinization by sodium chloride. Synanthropic representatives of local flora that have adapted to salinization are characterized by increased concentrations of salinizing ions; redistribution of chlorides, with their predominant accumulation in above-ground organs; selective absorption with respect to sodium, chloride, and potassium ions; and decreased activity of hydrogen ions in cells.
