Optimization of methods for reclamation of technogenically saline soils.

The paper considers the content of readily soluble salts of technogenic origin and the patterns of their spatial distribution in the soils of oil-contaminated floodplain ecosystems of Western Siberia within the middle taiga subzone. The revealed changes make it possible to assess the ecological state of the studied soils as unsatisfactory. Based on the results of the study of the basic parameters of technogenically saline soils (chemistry, degree of salinity, stock of toxic salts), proposals for the recultivation of technogenic soil salinity have been developed.
