Soils prepared by electrodialysis and acetic acid treatment released different amounts of non-exchangeable cations, when the H-soils were allowed to react with H-resin kept in a cellophane bag and also with 0.01M CaCl2 solution at 80°C. The release of non-exchangeable cations increased in the order: Mg > Ca > Na > K for both the soils. The amount of different non-exchangeable cations released after 24 day contact with H-resin were much lower in the case of the electrodialysed soil than that treated with acetic acid. In presence of CaCl2 solution, the electrodialysed soil released somewhat higher amount of non-exchangeable cations than the acetic acid treated soil.
