Classification

This soil is classified as a medial, amorphic, mesic Eutric Fulvudand. It has developed on volcanic ejecta ash parent material in a pasture land with a slope of 1% and elevation of 17 meters above sea level. The soil experiences well drainage, moderately rapid permeability, and udic soil moisture regime with average annual air temperature of 13 degrees Celsius and annual precipitation of 205 centimeters. The soil profile consists of an Ap horizon from 0-27 centimeters underlain by 2BA, 2Bw1, 2Bw2 and 2C1 horizons down to a depth of 160 centimeters.
