NW-Thailand, Luvisols occur mainly on intermediate to ultrabasic
igneous rocks. Exceptional occurrences were found at lower slope
position below the outlets of carbonate rich seepage water. Luvisols on
igneous rocks have commonly high clay contents, with crumb to
subangular blocky structure in the topsoil, and angular blocky to
prismatic structure in the subsoil (Argic horizon). Luvisols are more
fertile than Alisols and Acrisols. These soils are mostly used for
maize and upland rice production. Profiles of Luvisols on latite (left) and claystone (right). | |
