The rhizosphere in soil environments refers to the narrow zone of soil influenced by the root and exudates. Microbial populations in the rhizosphere can be 10 - 100 times larger than the populations in the bulk soil. Therefore, the rhizosphere is bathed in root exudates and microbial metabolites and the chemistry and biology at the soil-root interface is governed by biotic (plant roots, microbes) and abiotic (physical and chemical) interactions. <P> The research on biotic and abiotic interactions in the rhizosphere should, thus, be an issue of intense interest for years to come. This book, which consists of 15 chapters, addresses a variety of issues on fundamentals of microscopic levels and the impact on food chain contamination and the terrestrial ecosystem. <P> It is an essential reference work for chemists and biologists studying environmental systems, as well as earth, soil and environmental scientists. * 15 chapter book, which addresses a variety of issues on fundamentals of microscopic levels and the impact on food chain contamination and the terrestrial ecosystem.
