Abstract
The vanadium contents in the surface horizons of the Hawaiian soils range from 190 ppm to a high of 1520 ppm, with an average of 450 ppm. The very high concentrations are confined to the Humic Ferruginous Latosol Group. Thus, the vanadium contents of the Hawaiian soils are higher than those of other arable soils reported in the available literature. The amount of vanadium in the soil is influenced by the amount found in the parent material but the concentration of the element is more clearly a reflection of the weathering processes. In the Hawaiian Islands, where the major soil-forming process is latosolization, vanadium accumulates in the soil profiles. This characteristic may be used to advantage to find lithologic discontinuities in soil profiles. The concentration ratios derived in this study reflected the weathering state of the soils. When these ratios were plotted against rainfall they fell into the natural soil grouping used by soil classificationists. A correlation between the concentration of vanadium and titanium was observed in the Humic Ferruginous Latosol Group.
