Soil horizons

FITZPATRICK, E.A.

Description :
There are many more possibilities for designating horizons and layers in field descriptions than there are when applying the defined diagnostic horizons that are used in Soil Taxonomy. The first set are based on qualitative judgements, the latter are based on quantitative measurements. The Soil Survey in the United States has found it useful to keep the two kinds of horizon designations separate.
