The Evolution and Classification of Soils

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 classification of soils originated from three main sources: from early empirical soil surveys, from folk soil classifications and from scientific theory of pedology. In terms of evolution, soil classification methods can be broadly categorized into ancient, early/pre-modern and modern methods of soil classification. In terms of scope, they can be classified as local/national, regional and international.It is hoped that this comprehensive text will help to rally soil scientists around the world to develop an acceptable classification system for soils. This reference book can be used to illustrate the current state of national and international soil classification systems. This book provides modifications to classification systems to meet new demands. This book serves as a foundation for the revision of existing soil taxonomies and the creation of new ones. It provides the taxonomic keys necessary for the classification of soils in a form that can be used easily in the field. Readers and professionals of this field will find this text very valuable.
