Description: Currently, laboratory measurements are definitive for identifying andic soil properties in both the USDA Soil Taxonomy (Soil Survey Staff 1999) and the World Reference Base for Soil Resources (FAO/ISRIC/ISSS 1998). Andic soil properties, as described in Soil Taxonomy, result mainly from the presence of significant amounts of allophone, imogolite, ferrihydrite or aluminum- humus complexes in soils. The required properties are high acid-oxalate extractable aluminum and iron percentages, low bulk density, and high phosphate retention. In addition, glass is a common component of andic soils of the Inland Northwest region (McDaniel and others 2005).

Keywords: volcanic ash-cap soils, andic soil properties, Idaho, Inland Northwest
