* Builds on the success of the previous editions to present an unparalleled resource on soil formation and classification. *12 page color plate section featuring soil profiles. * Inclusion of new classification systems in China and Brazil.
Soils are natural bodies wherein inorganic components derived from geologic materials combine with organic materials produced by biological activity in ecosystems. The nearly infinite combinations of geologic materials and biological diversity of life on earth have produced a staggering array of chemical, physical, and biological reactions that over time have created the soils that we observe today. In the United States more than 23,000 kinds of soil are formally identified, and the number of soils in the world is not known.
Soil Genesis and Classification, Sixth Edition builds on the strong foundations of this venerable soil science text to present the most current concepts on how soils are formed and sustained within the dynamic changes of ecosystem successions and climatic dynamics. The sixth edition has been fully revised and updated, incorporating more detailed data regarding specific examples of how soils have acquired various characteristics. Methods of communicating and analyzing spatial information have been expanded in light of the latest technological advances. Color plates have also been added to allow readers a better visualization of various soils.
Soil Genesis and Classification, Sixth Edition is a comprehensive work that meets the diverse range of needs from soil science students professionals in fields ranging from agriculture and ecology to civil engineering. The well-established text will be a vital source of information for those with a need to better understand soils and their various impacts on ecosystem functions, on environmental quality, and on the multitude of human endeavors to sustain human life on earth.
