Book 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 differentiation of soils. In each case, the introductory reminders summarize the physicochemical and mineralogical principles necessary for understanding the text. The nomenclatures rely systematically and simultaneously on the two most commonly used classifications: Soil Taxonomy and World Reference Base. This reference manual is aimed at students of the undergraduate and graduate courses, but is also intended for workers and scientists in this subject area (geologists, pedologists, agronomists, land-use planners, foresters, etc.) as well as for all those concerned with or interested in protection of the environment.

Book Description
These lecture notes describe the major soils of the world and their properties, genetic formation, regional distribution, their management and associated land use. The World Reference Base for Soil Resources (WRB) is used throughout the text, as the basis for a universal classification system for soil correlation. The aim of the publication is to make the WRB accessible to young scientists. It is intended to facilitate the study of soils and the exchange of soil information, and provides a common language for soil science.

Book Description
Developments in soil classification have accompanied parallel progress in our understanding of the soil system. However the theories behind the classifications and the purposes for which they were created have changed over time. The editors hope that this comprehensive synthesis will help to rally soil scientists around the world to develop an acce

Book Description
This publication is a revised and updated version of World Soil Resources Reports No. 84 and 103 and presents the international soil classification system. Every soil in the world can be allocated to one of the 32 Reference Soil Groups as defined in this document, and can further be characterized by a set of qualifiers. The resulting soil name provides information on soil genesis, soil ecological function and soil properties relevant for land use and management. The same system, refined slightly, may be used to name the units of soil map legends, thereby providing comprehensive spatial information. By accommodating national soil classification systems, the World Reference Base facilitates the worldwide correlation of soil information.

Book Description
An understanding of the characteristics and the ecology of soils, particularly those of forest ecosystems in the humid tropics, is central to the development of sustainable forest management systems. The present book examines the contribution that forest soil science and forest ecology can make to sustainable land use in the humid tropics. Four main issues are addressed: characteristics and classification of forest soils, chemical and hydrological changes after forest utilization, soil fertility management in forest plantations and agroforestry systems as well as ecosystem studies from the dipterocarp forest region of Southeast Asia. Additionally, case studies include work from Guyana, Costa Rica, the Philippines, Malaysia, Australia and Nigeria.

Book Description
Now in it's third edition of World Soils provides a concise account of the soils of the world. It has been completely revised to include developments in the last decade in pedology and soil science. The introduction provides a definition of soils and outlines the author's approach. Successive chapters examine the composition, factors and processes behind the formation of soils. The topic of soil classification is dealt with in a user-friendly manner and includes an historical overview leading to the current FAO-Unesco Soil Map of the World system. The 28 major soil groups are described and their formation discussed. Chapters on soil mapping and soil use are also included. World Soils is written for a wide readership including students of environmental science, geography, ecology, forestry and agriculture, as well as the many other disciplines of study which include some consideration of soil as a natural resource. It will be useful to sixth-form students as well as first and second year undergraduates.
