The Soils Of The Usa

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 divides Antarctica into eight ice-free regions and provides information on the soils of each region. Soils have been studied in Antarctica for nearly 100 years. Although only 0.35% (45,000 km2) of Antarctica is ice-free, its weathered, unconsolidated material qualify as “soils”. Soils of Antarctica is richly illustrated with nearly 150 images and provisional maps are provided for several key ice-free areas.

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

change is simply described by the rate of income and rate of loss. Our home's energy budget, our firm's inventory, our nation's debt, and humanity's numbers all have accounts that change at rates that are equal to the inputs minus the outputs. Jenny's "system view" of the soil was carried into the fertile fields of Midwestern American prairies from the laboratories of Switzerland in the late 1920s. Jenny's rate equations provided the other paradigm or world view that, I recall, brought us to the threshold of systems ecology as it later evolved in the second half of the twentieth century. As if world renown in the specialties of pedology and soil chemistry were not enough for one lifetime, excerpts below remind us that Hans Jenny has also been a perceptive outdoor field ecologist since his early Alpine expeditions with Braun Blanquet in the mid 1920s. Jenny's ecosystem studies in the pygmy forest, a further classic example of a soil-plant system "run down" over hundreds of thousands of years since its origin, continue to occupy some of the vigorous retirement time near his farm in Mendocino County. But each specific, quantitative case study, and each research area conserved (with additional hard work) for further study by future generations, fits into Jenny's coherent world view. It is that view, and its legacies of discovery and of tangible landscape preserves, which we are privileged to share with their originator in this volume.

This is the first book to comprehensively discuss Ecuadorian soils. Richly illustrated, it provides information on the unique characteristics and distribution of these soils. Due to the influence of the Andes, which vastly modified the climate and parental materials, a relative small country like Ecuador has a wide variety of soil orders, rarely found in other countries. The country is divided into three distinctive regions by the Andes: The Coastal Plain, the Andean Highlands, and the Amazonia Region each with different soil development, influenced by the varying conditions in that region. It is also necessary to consider the Galapagos Islands as a separate region with a particular climate and parental material.

Mexico is an extensive country with an extremely complex mosaic of landscapes. The soils of Mexico have still not been completely studied, and there are few publications available on this subject. This book provides a state-of-the-art view on Mexican soils, their geographical distribution, their use and degradation. This is a first attempt to give a systematized characteristic of the soil resources of Mexico. Land resources of the second-biggest economy in Latin America are critical for its sustainable development, and a demand for adequate soil information is high. The information contained within can be used for any soil-related research done in Mexico and in neighboring countries. The book includes detailed characteristics of soils of all the physiographic regions of Mexico with maps, photos and explanatory schemes. The book is based on the experiences of the authors in research and soil survey, as well as on the existent, mainly ‘grey’ literature on Mexican soils. The book is recommended for researchers and university readers, students of all levels and decision-makers, working in the area of soil science, environmental issues, Earth sciences, land management and nature conservation.

This open access book synthesizes leading-edge science and management information about forest and rangeland soils of the United States. It offers ways to better understand changing conditions and their impacts on soils, and explores directions that positively affect the future of forest and rangeland soil health. This book outlines soil processes and identifies the research needed to manage forest and rangeland soils in the United States. Chapters give an overview of the state of forest and rangeland soils research in the Nation, including multi-decadal programs (chapter 1), then summarizes various human-caused and natural impacts and their effects on soil carbon, hydrology, biogeochemistry, and biological diversity (chapters 2–5). Other chapters look at the effects of changing conditions on forest soils in wetland and urban settings (chapters 6–7). Impacts include: climate change, severe wildfires, invasive species, pests and diseases, pollution, and land use change. Chapter 8 considers approaches to maintaining or regaining forest and rangeland soil health in the face of these varied impacts. Mapping, monitoring, and data sharing are discussed in chapter 9 as ways to leverage scientific and human resources to address soil health at scales from the landscape to the individual parcel (monitoring networks, data sharing Web sites, and educational soils-centered programs are tabulated in appendix B). Chapter 10 highlights opportunities for deepening our understanding of soils and for sustaining long-term ecosystem health and appendix C summarizes research needs. Nine regional summaries (appendix A) offer a more detailed look at forest and rangeland soils in the United States and its Affiliates.
