11 themes two themes to start soil orders soil suborders NACIS missoula, mt october 2008

12 two themes soil orders soil orders are differentiated by the presence or absence of diagnostic horizons or features that reflect soil forming processes. Distinctions among orders aid in understanding soils and remembering them on a grand scale. Thus, the distinctions between orders are based on the markers left by processes that experience indicates are dominant forces in shaping the character of the soil. soil suborders if the soils in a given taxon are thought to have had significantly different genesis, the intent has been to sort out the differences in the next lower category.

14 U.S. soil taxonomy Order (11) Suborder (60) Great Group (~303) Subgroup (~1,200) Family Series (~17,000) 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.
