Level 4 Guiding Question: How are soils classified?
The soil classification system described in Soil Taxonomy (Soil Survey Staff, 1975) focuses on soil properties that for the most part can be measured quantitatively rather than on soil-forming processes or factors. Yet, the system certainly can not exclude soil genesis since many soil properties quantified have considerable significance in soil genesis. General objectives of the new system are to make the characteristics of various soils easier to remember, to make clearer the relationships among soils and between soils and other elements of the environment, and to provide a basis for developing principles of soil genesis and soil behavior that have prediction value.
