Soil Genesis and Classification reviews a spectrum of soil classification systems and presents the culmination of more than two decades of testing and revisions in the U.S. Soil Taxonomy, the most detailed and comprehensive system for soil classification. The classic textbook explains the function and use of soils, soil formation and categorization, and details how this dynamic natural entity evolves from natural factors and processes and interfaces with ecosystems and human endeavors. For the fifth edition, the authors have included the new nomenclature and systematic structure of soil classification categories, as well as new analytical techniques to more quantitatively identify soil properties and define class limits in Soil Taxonomy. This comprehensive work covers the diverse needs of soil science instructors, majors, minors, and graduate students, and serves as an outstanding reference for soil scientists, agricultural and natural resources engineers and economists, and others in related fields such as ecology, natural resources, and land use and planning.

Soil Genesis That Studies The Evolution Of Soils And The Changes Taking Place In Soil Bodies Has Received Increasing Interest And Attention In The Twentieth Century, And This Yet Continues. Despite The Fact That The Indian Soil Scientists Have Made Much Investigation Into The Subject Of Soil Genesis, Classification, Survey And Evaluation, There Are Very Few Books That Provide Ample Instructional Material Relevant To Situation In India. The Present Book Is Primarily Focused On The Study Of Geological Conditions Of India. Briefly Outlining The Fundamental Concepts Of Soil Genesis And Acquainting The Readers With Rich Minerals Present Under The Soil, The Book Provides A Detailed Study Of The Factors And Processes Of Soil Formation, Including Description And Interpretation Of The Soil Profile And Patterns Of Soils Occurring On The Surface Of The Earth. Furthermore, It Lays Down The Purpose And The Historical As Well As Modern Basis Of Classification Of Soils In Different Countries Across The World. It Particularly Provides An In-Depth Study Of Soils Prevalent In The Varied States Of India In Addition To The Assessment Of Productivity Of Bench Mark Soils Of The Country. The Book Also Covers Significant Areas Like Remote Sensing, Soil Survey, Land Use, Land Capability Classification, Land Irrigability Classification, Land Evaluation, Land Use Planning And Cartography. Considerable Authentic Information Has Been Drawn From The Works Of Indian Soil Scientists In These Disciplines Which Has Necessarily Added To The Value Of The Book.Designed As A Textbook, Its Approach To The Subject Is Reader-Friendly. Its Simple Language And Lucid Style Make It Accessible Even To Average Students. It Is Hoped That The Book Will Prove Immensely Useful And Informative To Students And Teachers Of Geology As Well As Soil Surveyors.

The Genesis and Classification of Cold Soils exposes the processes involved in the development of the principal kinds of soils that occur in cold regions and introduces readers to the classification of those soils. The book uses the terminologies and concepts of the description of soils provided by the Soil Taxonomy of the United States. Topics covered in the book include aspects of temperature relationships in cold soils; effects of freezing temperatures on the soil properties; the salient features of the U.S. Soil Taxonomy system; and the taxonomies of Canada, the U.S.S.R., and The Food and Agriculture Organization (FAO). Pedologists, agriculturists, engineers, and researchers will find the book insightful.

Covering wetlands soils from Florida to Alaska, Wetland Soils: Genesis, Hydrology, Landscapes, and Classification provides information on all types of hydric soils. With contributions from soil scientists who have extensive field experience, the book focuses on the soil morphology of the wet soils that cover most wetlands from the subtropics northward. No previous book has been devoted solely to the subject of hydric soils and their landscapes. The book is well organized and divided into three parts. Part I examines the basic concepts, processes, and properties of aspects of hydric soils that pertain to virtually any hydric soil. It provides a general overview and important terms and concepts. Part II covers the soils in specific kinds of wetlands and the different functions they perform. Part III emphasizes special wetlands conditions such as soils composed of sand, organic soils in northern North America, prairie wetlands, wetlands in saline situations, dry climates, and wetlands with modified hydrology. Whether you are an expert in soil science, or just need a crash course, this reference prepares you to work with real wetlands-outdoors. Written for scientists without a background in soil science and comprehensive in scope, Wetlands Soils: Genesis, Hydrology, Landscapes, and Classification provides basic and advanced coverage, explaining the fundamentals of hydric soils in terms even a non-soil scientist can understand.
Soils: Genesis and Geomorphology is a comprehensive and accessible textbook on all aspects of soils. The book's introductory chapters on soil morphology, physics, mineralogy and organisms prepare the reader for the more advanced and thorough treatment that follows. Theory and processes of soil genesis and geomorphology form the backbone of the book, rather than the emphasis on soil classification that permeates other less imaginative soils textbooks. This refreshingly readable text takes a truly global perspective, with many examples from around the world sprinkled throughout. Replete with hundreds of high quality figures and a large glossary, this book will be invaluable for anyone studying soils, landforms and landscape change. Soils: Genesis and Geomorphology is an ideal textbook for mid- to upper-level undergraduate and graduate level courses in soils, pedology and geomorphology. It will also be an invaluable reference text for researchers.
Volcanic eruptions are generally viewed as agents of destruction, yet they provide the parent materials from which some of the most productive soils in the world are formed. The high productivity results from a combination of unique physical, chemical and mineralogical properties. The importance and uniqueness of volcanic ash soils are exemplified by the recent establishment of the Andisol soil order in Soil Taxonomy. This book provides the first comprehensive synthesis of all aspects of volcanic ash soils in a single volume. It contains in-depth coverage of important topics including terminology, morphology, genesis, classification, mineralogy, chemistry, physical properties, productivity and utilization. A wealth of data (37 tables, 81 figures, and Appendix) mainly from the Tohoku University Andisol Data Base is used to illustrate major concepts. Twelve color plates provide a valuable visual-aid and complement the text description of the world-wide distribution for volcanic ash soils. This volume will serve as a valuable reference for soil scientists, plant scientists, ecologists and geochemists interested in biogeochemical processes occurring in soils derived form volcanic ejecta.
