ABSTRACT
Soil Taxonomy, in spite of its highly hierarchical look with four levels, is primarily a system for naming soils. Its philosophy, therefore, is not so distant from what one would think is that of the WRB. As all systems of this type do, it embodies, regroups and organizes the knowledge of very many specialists. They play a very useful role in their country of origin. With a minimum of familiarity, the terminology it proposes is very easily deciphered. It is less easy to construct! But it has many defects: • It is relatively complex. • Its structure is not always as rigorous as it might seem to be.
