Soils are one of the major resources of Pacific Islanders. Despite the islanders' dependence on the marine environment, soils are the source of a major proportion of the food, building materials, clothing, and medicines. The islands vary enormously in size, geomorphology, and geology, with a resultant diversity in soils. From the small atolls to the large continental islands, traditional technologies have been developed to effectively utilize this invaluable resource (Morrison et al. 1994). Many Pacific Island groups earn significant portions of their foreign exchange earnings through the export of agricultural and forest products (Browne 2006).
