A SOURCE OF ERROR IN CATIONEXCHANGE CAPACITY DETERMINATIONS BY FLAME-EMISSION PROCEDURES A PROCEDURE to determine the cation-exchange capacity (CEC) using nonfixable cations for saturation and extraction was attempted at this laboratory, adapting a semimicro-procedure suggested by Sawhney et al. in which 0.1-g. clay samples in 15-ml. centrifuge tubes are used. In the adaptation, a 5-g. sample of air-dry soil in
