Abstract

This report presents the results of field and experimental studies of water-physical properties of soils of oil-contaminated floodplain ecosystems of the mid-taiga subzone of Western Siberia. Features and basic patterns of their change in various contamination zones (epicenter - impact zone) are revealed. The state of water-physical properties of technologically contaminated soils is compared with background counterparts. Recommendations on the use of basic soil-hydrological constants (range of active moisture, wilting moisture, and field moisture capacity) in the technology of phytomelioration are suggested. Study objective: to analyze characteristics of the impact of oil pollution on water-physical properties of alluvial soils and the possibility of using obtained data for the purposes of remediation works.
