Ion activities and the electric conductivity of water extracts from virgin and ameliorated soils of the Dzhanybek Research Station

摘要

The applicability of data on ion activity in water extracts for assessing salinization-desalinization processes in virgin and ameliorated solonchakous solonetzes and meadow-chestnut soils of the clayey semidesert (the northern part of the Caspian Lowland) is tested. A scheme for the calculation of Cl~- concentration in the water extract on the basis of data on the activity of Cl~- ion and salt concentration in the water extract measured by the electrical conductivity method is suggested.
