Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

Principles and Practice of Soil Science, FourthEditionprovides a current and comprehensive introduction to soilscience for students in the fields of environmental andagricultural science, ecology, soil and land management, naturalresource management and environmental engineering. Covers all aspects of soil science including soil habitat,processes in the soil environment and soil management. Emphasizes the applications of soil science to the solution ofpractical problems in soil and land management. Highlights real world examples drawn from the author’sinternational experience in the field. Includes an expanded colour section of soil profiles and otherfeatures, and greater coverage of international soilclassification Features new problem sets and questions at the end of eachchapter, designed to reinforce important principles. An answer keyis provided at the end of the text. Artwork from the book is available to instructors online atwww.blackwellpublishing.com/white

Completely revised and updated, incorporating almost a decade's worth of developments in this field, Environmental Soil Science, Third Edition, explores the entire reach of the subject, beginning with soil properties and reactions and moving on to their relationship to environmental properties and reactions.

Forest soils are the foundation of the entire forest ecosystem and complex, long-term interactions between trees, soil animals, and the microbial community shape soils in was that are very distinct from agricultural soils. The composition, structure, and processes in forest soils at any given time reflect current conditions, as well as the legacies of decades (and even millennia) of interactions that shape each forest soil. Reciprocal interactions are fundamental; vegetation alters soil physical properties, which influence soil biology and chemistry, which in turn influence the growth and success of plants. These dynamic systems may be strongly influenced by intentional and unintentional management, ranging from fire to fertilization. Sustaining the long-term fertility of forest soils depends on insights about a diverse array of soil features and changes over space and time. Since the third edition of this successful book many new interests in forest soils and their management have arisen, including the role of forest soils in sequestering carbon, and how management influences rates of carbon accumulation. This edition also expands the consideration of how soils are sampled and characterized, and how tree species differ in their influence on soil development. Clearly structured throughout, the book opens with the origins of forest soil science and ends with the application of soil science principles to land management. This new edition provides: A completely revised and updated Fourth Edition of this classic textbook in the field A coherent overview of the major issues surrounding the ecology and management of forest soils Global in scope with coverage of soil types ranging from the tropical rainforest soils of Latin America to the boreal forest soils of Siberia New chapters on Management: Carbon sequestration; Evidence-based approaches and applications of geostatistics, GIS and taxonomies A clear overview of each topic, informative examples/case studies, and an overall context for helping readers think clearly about forest soils An introduction to the literature of forest soil science and to the philosophy of forest soil science research This coherent overview of the major issues surrounding the ecology and management of forest soils will be particularly useful to students taking courses in soil science, forestry, agronomy, ecology, natural resource management, environmental management and conservation, as well as professionals in forestry dealing with the productivity of forests and functioning of watersheds.

Long-awaited second edition of classic textbook, brought completely up to date, for courses on tropical soils, and reference for scientists and professionals.
