Haplotorrox
A soil profile of a Haplotorrox in Hawaii. This soil formed in residuum from a basaltic lava flow. (Soil Survey Staff. 2015. Illustrated guide to Soil Taxonomy. U.S. Department of Agriculture, Natural Resources Conservation Service, National Soil Survey Center, Lincoln, Nebraska)
Haplotorrox have a low base saturation in one or more subhorizons within a depth of 125 cm. Torrox are the Oxisols of arid regions. They have an aridic moisture regime, and, due to limited leaching, many of them have a higher base saturation than other Oxisols. Unless they are irrigated, Torrox are unsuitable for growing common agronomic crops. However, they are well suited to a variety of crops if irrigation water and fertilizer are applied. Torrox are known to occur only in Hawaii in the United States and perhaps in some areas of Australia.
