Field leaching investigations relative to the reclamation of saline and alkali soils generally require considerable land area, as well as time and personnel, for establishing and maintaining such studies. Concurrent with a field leaching experiment a laboratory leaching study was made to determine the relationship between results obtained from undisturbed cores in the laboratory and those obtained from field plots. Changes in infiltration rate, soluble salts, and exchangeable‐sodium‐percentage due to leaching, with and without gypsum, were compared. In view of the similarity of results obtained from undisturbed cores in the laboratory and field plots, it appears that soil cores, properly encased, can be used to predict with reasonable accuracy the reclaimability of saline and alkali soils. Although laboratory studies will not replace field investigations, cores could be used in making preliminary studies during period outside of the field season. The information thus obtained could then be used in the final selection of treatments to be considered in the field.
