The Soil Classification System and Its Application in

Classification of soils, for instance, is indispensible to the soil survey program of mapping the soils of Arizona. Soil surveys, in turn, can be used to apply the principle functions of soil science to agriculture, forestry and engineering to predict soil behavior under defined use and management or manipulation.

Lecture Notes Principles of Soil Classification

Classification Principles: • A practical grouping into reference groups that share an assemblage of features which cause distinct behaviour, i.e. ecological function and implications for soil management. So, the reference groups are quite distinct and can serve as the basis for making general state- ments about soil suitability and management strategies. • Second-level qualifiers are ...

Soil classification

Soil classificationis the separation of soil into classes or groups each having similar characteristics and potentially similar behaviour. A classification for engineering purposes should be based mainly on mechanical properties, e.g. permeability, stiffness, strength. The class to which a soil belongs can be used in its description.
