Abstract

A new and rapid soil column technique is described that can verify model calculations on transport and exchange of cations in soil, using equipment for high-performance liquid chromatography (HPLC). Breakthrough curves of cations are presented and compared with results of a model that simulates transport and exchange processes in a soil column. The small column dimensions and the high flow rate allow leaching of individual columns to be completed within one day. Equiulibrium is established almost instantaneously between the leaching solution and the soil in the column. (Abstract retrieved from CAB Abstracts by CABI’s permission)
