Description

This profusely illustrated book gives an exhaustive account of the principal types of soils of our planet. The "progressive descent of weathering fronts" model, recognized and used by eminent international scientists is the guiding principle of choice to link the observations and to give the reader a synthetic and coherent view of the differentiati
