Studying Soil Profiles


In part C we will treat the formation of the main genetic soil horizons that are used as diagnostic criteria in the international soil classification systems (FAO-Unesco and Soil Taxonomy). You will be able to describe the formation of these diagnostic horizons, and thereby, of the different genetic soil types, in terms of the physical, chemical and biological processes you studied in Part B.
