The use of nickel as a displacing ion in the determination of exchangeable cations and cation-exchange capacity was evaluated using several British Columbia soils. The values for exchangeable cations and cation-exchange capacity for the soils examined, using 0.25 normal neutral nickel chloride, were higher than those obtained by the ammonium acetate extraction method. For the most part, in samples examined, values were found to be more readily and consistently reproduced with the nickel chloride extractant. Dispersion of soil organic matter and silicate clay minerals was negligible, and the washing step involving ethanol has been eliminated.

One of the most important properties of zeolitized volcaniclastic materials is the cation exchange capacity (CEC). Numerous techniques are available for measuring CEC and the methylene blue absorption (MBA) (Nevins & Weintritt, 1967) and the ammonium acetate saturation (AMAS) (Chapman, 1965) methods are two of those commonly used. The aim of this study was to compare the results obtained by the two methods when used with zeolite-rich materials.
