Physicochemical properties of two sandy soils taken from a present and from a former sewage farm were studied during a 2.5 years column experiment, in which lime and irrigation water of various compositions were applied. The amount of exchangeable bases and base saturation percentage in both soils changed markedly during the experiment. These changes were governed by changes in soil pH. The specific surface area as well as the cation exchange capacity were closely related to the organic carbon content in the soil profile. The surface charge density of both soils was roughly equal and independent of the soil depth.
