Cation Exchange Behavior of a Zeolitic Sodic Soil1

Abstract

Abstract

A strongly saline-sodic Pond clay loam soil was found to contain approximately 22% of the zeolite analcime. The anomalous cation exchange behavior of this soil was attributed to the presence of analcime. Cation exchange capacity (CEC) and exchangeable Na (Ex Na) measured with K or NH4 were more than twice those measured with Li, Mg, or Ba. The exchange of K for Na, Mg for Na, and Na for K, by incremental extraction, gave evidence that the excess Na of the soil was released by exchange rather than by mineral dissolution, and that analcime was the source of that excess Na.

Extraction of the analcime soil with Li, Mg, or Ba offered a fair measure of the exchange properties of the nonzeolitic portion of the soil.
