Abstract

Three soils formed from volanic ash on the Aleutian Islands and adjacent Alaska Peninsula were characterized and classified according to Soil Taxonomy to test some of its recent revisions. All three soils have bulk density <0.9 Mg m-3, acid-oxalate extractable Al of 15 to 25 g kg-1, phosphate retention >90%, and sand fraction dominated by volcanic glass. These properties meet the endic soil properties and qualify for the provisional Andisol order as defined by the International Committee on the Classification of Andisols (ICOMAND). However, two of the three pedons also meet the laboratory criteria for Spodosols. -from Authors
