order (11 taxa): this category is based largely on soil forming processes as

indicated by the presence or absence of major diagnostic horizons. A given

order includes soils whose properties suggest that they are not dissimilar in

their genesis. They are thought to have been formed by the same general

genetic processes.

suborder (60 taxa): suborders are subdivisions of orders that emphasize

genetic homogeneity . The presence or absence of properties associated with

wetness, climatic environment, major parent material, and vegetation.
