Assessment of the current physical and chemical status of the alluvial soils of the Volga-Akhtuba floodplain and the Volga delta

The article dwells upon the study of current physico-chemical status alluvial dark-humus soils floodplain hayfields Volga-Akhtuba and Volga delta. Alluvial are formed in special semiaquatic conditions; they result soil-forming processes. Considered to be dynamic both natural anthropogenic conditions. They have subordinate remain barriers accumulators various chemical elements while performing a sanitary hygienic role delta ecosystems. Due increased load on soils, their status, which affects migration elements, becomes particularly significant. characterized by polynomial profile soil horizons varying development degrees alternate with river sediments. studied landscapes good agrophysical relatively satisfactory agrochemical condition. It was found that bunds territory as well negative impact actively develop secondary salinization. focus is properties content humus nutrients. According granulometric composition, medium heavy loamy, supply productive moisture. In Southeastern part floodplain, processes salinization, dehumification alkalization most present.
