ABSTRACT: The article shows the results of long-term studies aimed at assessing the formation of ameliorative regime of natural-anthropogenic complexes in Kalmykia. Initial parameters have been presented for models of forming the water-salt regime of the irrigated agricultural landscapes with their comprehensive amelioration in semi-desert and desert areas of Kalmykia. The influence of water-salt regime of soils on the productivity of saltmarsh bluegrass and alfalfa has been studied, and the threshold of salt tolerance for these crops has been defined. The technology of recovering re-salinized irrigated land with the use of reclaimer crops has been developed, which makes it possible not only to rehabilitate the soils that are adverse due to re-salinization, but to obtain extra quality forage as well.

KEYWORDS: comprehensive melioration; ameliorative regime; water-and-salt balance; phyto-ameliorants; salt tolerance; yield
