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.

Soil Genesis and Classification, Sixth Edition, builds on the success of the previous editions to present an unparalleled resource on soil formation and classification. Featuring a color plate section containing multiple soil profiles, this text also includes information on new classification systems and emerging technologies and databases with updated references throughout. Covering the diverse needs of both the academic and professional communities, this classic text will be a must have reference for all those in soil science and related fields.
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 northw
