Readers will discover root-soil interactions and how to use them to manage the quality and productivity of our soils. Ranging from those identifiable from a moving vehicle, to those only elucidated with powerful molecular tools, the rhizosphere is examined by 28 authors in three sections: Macro-scale-- Learn the four classes of root that deal with soil spatial and temporal variability. Meso-scale-- Examine the dynamic processes that predicate much of the diversity and activity of the rhizosphere. Micro-scale-- Looking at microbes themselves, explore topics such as deleterious bacteria as bio-herbicides, a cutting edge discussion of the molecular genetic basis for quorum sensing in a rhizobium species, and interactions among soybean, bradyrhizobia, and VAM fungi.Also available: Dryland Agriculture, Second Edition - ISBN 0891181601 Agroecosystems Analysis - ISBN 0891181539 Soybeans: Improvement, Production, and Uses, Third Edition - ISBN 0891181547The American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America are prominent international scientific societies headquartered in Madison, Wisconsin.
