Information
Copper(II) acetate spectrophotometry method (CASM) was used for the rapid and convenient determination of cation exchange capacity (CEC) in soils. This method is composed of a single-step exchange reaction that adsorbs copper and is measured through spectrophotometry. The CEC of 16 Korean soils were measured using 1M ammonium acetate method (AAM) and the CASM. The CEC values determined by CASM and AAM were not significantly different, and were highly correlated (r = 0.966**). Due to the convenience, cost effectiveness, and time saving analysis of CASM, this method is recommended for most soil laboratories to measure CEC in Korean soils. However, CASM may not be applicable for soils that have a much higher CEC (greater than 20 cmolc kg-1 ).
