Аннотация
Soil degradation is one of the common types of which is soil salination, is a serious limited factor of food security and sustainable territory development. It is necessary to pay a special attention on the first soil salination of arid regions, as arid climate leads to the active salt accumulation in the upper rooting soil horizons and gives rise to withdrawal of large land areas from economic turnover. The purpose of the this work is defining of the watersoluble salts specific features in soils of the river Volga delta upper level natural boundaries under the influence of natural factors. Botanic natural sanctuary “Svinoroiny meadow (Meshkovsky)” was chosen as a research object, associated with the new Caspian coastal plain within distribution of the river Volga delta Baer knoll landscape. Water extract ions analysis and soil solution toxicity calculation on the area were carried out from 1979 till 2020. It was revealed that dynamics direction of salination types are defined by the ascent of water predominanceon over descending on the area in the conditions of the territory exudative water regime. Salination increase to a great extent depends on the great volumes of spring-summer floods and appropriate ground water level rise, area desalination is defined by atmospheric precipitations quantity.
