This book describes and comprehensively illustrates all earth soils in accordance with the prevailing worldwide WRB classification. However, it goes far beyond description and definition, by presenting the soils in the context of the natural habitats in which they occur. The book is structured in line with ecological zones. Initially their location, the climate and the vegetation as well as the factors influencing the constitution of the soil are briefly presented. All soils representative of the corresponding ecological zone are then defined and described in detail. The very instructive photographs and graphs combine to make the publication an excellent reference book about the earth’s soils and their distribution.
