<p><b>An updated text exploring the properties of the soil microbial community</b></p> <p>Today, the environmentally oriented specialties of microbiology are shifting from considering a single or a few microbial species to focusing on the entire microbial community and its interactions.  The third edition of <i>Soil Microbiology</i> has been fully revised and updated to reflect this change, with a new focus on microbial communities and how they impact global ecology.</p> <p>The third edition still provides thorough coverage of basic soil microbiology principles, yet the textbook also expands students' understanding of the role the soil microbial community plays in global environmental health and human health. They can also learn more about the techniques used to conduct analysis at this level.</p> <p>Readers will benefit from the edition's expanded use of figures and tables as well as the recommendations for further reading found within each chapter.</p> <ul> <li>Considers the impact of environmental perturbations on microbial community structure as well as the implications for soil system functions</li> <li>Discusses the impact of soil microbial communities on food and health related issues</li> <li>Emphasizes the importance of soil microbial communities on the sustainability of terrestrial ecosystems and solutions to global issues</li> </ul> <p>This third edition is a suitable text for those studying soil microbiology and soil ecology at the undergraduate or graduate level. It also serves as a valuable reference tool for professionals working in the fields of reclamation and soil management.</p>

<p><b>DR. TATE</b> is Professor Emeritus at Rutgers University and held appointments in the Department of Environmental Sciences and the Environmental and Occupational Health Sciences Institute. The author conducted research at the leading edge of soil microbiology and taught soil microbiology and related courses. He is a fellow of the two leading scientific societies serving soil microbiologists (Soil Science Society of America, Agronomy Society). Dr. Tate served as the Editor-in-Chief of Soil Science and editor of the Journal of the Soil Science Society of America. At Rutgers, he was the Director of the undergraduate Environmental Science Program and Chair of the Department of Environmental Sciences.
<p>The environmentally oriented specialties of microbiology are in the midst of a major paradigm shift from a focus on single or a few key microbial species to consideration of the entirety of the microbial community and its interactions. This fully revised and updated edition focuses on the importance of soil microbial communities to sustainability of terrestrial ecosystems and solutions to global problems. Basic principles are covered, and details of the finer points of processes and their implications have been updated. This is a one-of-a-kind reference for advanced students and professionals.
