Since 1980, our understanding of the factors and processes governing the distribution of soils on the Earth’s surface has increased dramatically, as have the techniques for studying soil patterns. The approach used in this book relies on the National Resources Conservation Service databases to delineate the distribution of each of the eight diagnostic epipedons and 19 subsurface horizons, to identify the taxonomic level at which each of these horizons is used, to develop an understanding of the role of the factors and processes in their formation and to summarize our latest understanding of their genesis. A chapter is devoted to each diagnostic horizon (or combined horizons). This book is intended to serve as a textbook in soil geography, a reference book for geographers, ecologists and geologists and a tool for soil instructors, landlookers, mappers, classifiers and information technologists.

This book provides an overview of the distribution, properties, and function of soils in the U.S., including Alaska, Hawaii, and its Caribbean territories. It discusses the history of soil surveys and pedological research in the U.S., and offers general descriptions of the country’s climate, geology and geomorphology. For each Land Resource Region (LRR) – a geographic/ecological region of the country characterized by its own climate, geology, landscapes, soils, and agricultural practices – there is a chapter with details of the climate, geology, geomorphology, pre-settlement and current vegetation, and land use, as well as the distribution and properties of major soils including their genesis, classification, and management challenges. The final chapters address topics such as soils and humans, and the future challenges for soil science and soil surveys in the U.S. Maps of soil distribution, pedon descriptions, profile images, and tables of properties are included throughout the text.

This book narrates how the study of the soil became a science and institutionalized in the USA between 1860 and 1960. The story meanders through the activities, ideas, publications, and correspondence of people who influenced the progressions, that led to the budding and early blossoming of American and international soil science. Interwoven is a tale of two farm boys who grew up 900 km apart in the Midwest USA in the late 1800s and early 1900s. Emil Truog and Charles Kellogg met in the late 1920s and shared a natural connection to the soil. Both were practical pioneers and believed that understanding soils was crucial to helping people on the land make a better living. The USA is a big country, its soil science is geographically intertwined, and the cradle of its history primes back to a few people. “Soil Science Americana is an intellectual biography, not of one individual but of a new scientific field from its emergence to its complete coming of age.” — Louise O. Fresco, President, Wageningen University and Research “In a lively, personal voice, Hartemink traces the roots of modern soil science in the United States...creating a book that will engage both the expert and non-expert in the underappreciated field of soil science.” — Jo Handelsman, Director, Wisconsin Institute for Discovery “The intellectual master piece is of interest to soil scientists, general public and the policy makers, and will remain pertinent for generations to come.” — Rattan Lal, World Food Prize Laureate 2020, The Ohio State University

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.

This book, first published in 1965, was the first by a British soil expert in which he wrote a study of his subject from a geographical, not an agricultural or biological, viewpoint. Chapters 1-8 deal with the factors and processes in soil formation. Chapters 9-17 describe the soil groups of the different regions of the world – for example, desert and tundra, the boreal zone, the Mediterranean, and intertropical areas.

Encyclopedia of Geology, Second Edition presents in six volumes state-of-the-art reviews on the various aspects of geologic research, all of which have moved on considerably since the writing of the first edition. New areas of discussion include extinctions, origins of life, plate tectonics and its influence on faunal provinces, new types of mineral and hydrocarbon deposits, new methods of dating rocks, and geological processes. Users will find this to be a fundamental resource for teachers and students of geology, as well as researchers and non-geology professionals seeking up-to-date reviews of geologic research. Provides a comprehensive and accessible one-stop shop for information on the subject of geology, explaining methodologies and technical jargon used in the field Highlights connections between geology and other physical and biological sciences, tackling research problems that span multiple fields Fills a critical gap of information in a field that has seen significant progress in past years Presents an ideal reference for a wide range of scientists in earth and environmental areas of study

Geography is a component of Encyclopedia of Earth and Atmospheric Sciences in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Geographical perceptions can be traced from very ancient cultures, although geography as a science started its development during the eighteen century, it was firmly established after the Darwinian revolution and many of its fundamentals appeared during the nineteenth century. The history of geography is closely connected with the history of human society Geography embraces both the physical and human worlds, and aims to bridge natural and human sciences. For a geographer, although the environment and its conservation is a crucial item, it is also fundamentally concerned with the living standards of humankind. Although its wide embrace may be seen as a weakness, diversification is also strength and an attraction. Approaches are multidisciplinary, exploring the complex linkages between the cultural and the natural. These favor cross-cultural communication and mutual understanding at a global scale. There is a geographical basis to most of the outstanding political problems, and geographical reasons to explain them. The subject matter of the geography theme is presented basically on how the subject matter is taught presently at the universities, and following the many paths its practitioners are following in doing research. It introduces modern subject matters and goes much further than a simple description of places and travels. The theme has been divided into four main topics: Foundations, Physical Geography, Human Geography, and Technical matters. The scope of the foundation topic is to present an overview of the basis of the geographical field, its scope, history, methods, and its importance in education. The chapters included are Main Stages of the Development, Theory and Methods, and Geographical Education. The Physical Geography topic includes the historical background of the geographical study of the Earth natural environment, and the main fields cultivated by geographers. It consists of eight chapters on basic research fields, which are Geomorphology, Climatology, Hydrology, Biogeography, Soil Geography, Coastal Systems, Ocean Geography, Mountain Geoecology, and two chapters on environmental issues: Natural Hazards and Land Degradation and Desertification. In the Human Geography topic six chapters discuss the more current fields, that is: Population, Cultural and Social, Agricultural and Rural, Industries and Transport, Economic Activities and Urban Geography. Three chapters present subjects developed more recently: Medical, Political and Tourism geographies. Finally, the Regional approach is presented as the most traditional and integrative field. These volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
