Factors Influencing Hydraulic Conductivity of Soils in the Presence of Mixed-Salt Solutions¹

ABSTRACT

For a group of soils having variable clay content but nearly uniform clay-fraction mineralogy, relative hydraulic conductivity in the presence of mixed-salt solutions decreased markedly with increasing clay content, particularly at the lowest salt concentrations employed. The stability of a group of Hawaiian soils under high-sodium, low-salt conditions was greatly reduced by partial removal of the free iron-oxides. Replacing the Ca in percolating NaCl-CaCl₂ solutions with Mg measurably decreased soil hydraulic conductivity, although the effect was often negligible when comparisons were made at equivalent exchangeable-sodium-percentages.
