Abstract
The effects of 3 rates of application of Jalma, a gel-forming soil conditioner, with 4 waters of differing salinity on the water penetrability, weighted-mean diffusivity, soil swelling, and effective mean pore radius of loamy sand and loam soil columns were investigated. The waters used were a salt solution, distilled water, sewage, and well water. Diffusivities in untreated soil columns, were almost independent of water quality. Swelling generally decreased, while effective mean pore radius, water penetrability, and weighted-mean diffusivity increased with increasing water salinity and decreasing application percentage of Jalma for both soils.
