ABSTRACTSoil Taxonomy adopted by the Soil Conservation Service and used by soil scientists has not been readily accepted in many other disciplines. This lack of acceptance is particularly evident in many introductory courses in physical science at college level. Frequently, professors and textbooks refer to the 7th Approximation if they refer to the new system at all. A generalized presentation which correlates soil orders, vegetation biomes, and Koppen climates at a regional scale is proposed. Spatial coincidence of the three environmental subsystems provides an increased appreciation of Soil Taxonomy's nomenclature to detail environmental settings, diagnostic horizons, and quantified profile differences. The soil orders are displayed in a flow chart organized according to increasing soil development and decreasing water supplying capacity.
