  • Recommended Methods for Determining Soil Cation

    Cation exchange sites are found primarily on clay minerals and organic matter (OM) surfaces. Soil OM will develop a greater CEC at near-neutral pH than under acidic conditions (pH-dependent CEC). Thus, addition of an organic material will likely increase a soil's CEC over time.

    Jul 01, 1997 · A method for the rapid determination of CEC values in clays using au ethylenediamine complex of Cu was tested with different clays. The single-step procedure is fast and does not require sophisticated apparatus. The exchange with most cations—and even with those of heavy metals—is irreversible and can be carried out over a range of pH values.
