Experiments In Soil Biology And Biochemistry

Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils. Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life, soil biota and soil fauna are collective terms that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface. Soils are rich ecosystems, composed of both living and non-living matter with a multitude of interaction between them. Soils play an important role in all of our natural ecological cycles. They also provide benefits through their contribution in a number of additional processes, called ecosystem services. These services range from waste decomposition to acting as a water filtration system to degrading environmental contaminants. Soil biochemistry is one of the branches of soil science dealing with the formation and decomposition of soil organic matter, biochemical reactions of carbon, nitrogen, phosphorus, sulfur, metals and xenobiotic in soils, and biochemistry of the plant-root rhizosphere. The book will suit to the needs of students, teachers, scholars and general readers.

This publication has been written primarily to meet the requirements of the practical component of the course 'Soil Biology & Biochemistry' prescribed by the Education Division of the Indian Council of Agricultural Research as compulsory course for the students perusing PG studies in soil science. The publication is in instructional mode and is very well illustrated so as to serve as a kind of 'self help' document. No effort has been spared in presenting information in a clear and concise manner. It has exercises covering both soil microflora and fauna. Besides aspects relating to the enzymes and biochemical transformations of plant nutrients covered in, it has a chapter on the frontier area of Soil Biotechnology.

The fourth edition of Soil Microbiology, Ecology and Biochemistry updates this widely used reference as the study and understanding of soil biota, their function, and the dynamics of soil organic matter has been revolutionized by molecular and instrumental techniques, and information technology. Knowledge of soil microbiology, ecology and biochemistry is central to our understanding of organisms and their processes and interactions with their environment. In a time of great global change and increased emphasis on biodiversity and food security, soil microbiology and ecology has become an increasingly important topic. Revised by a group of world-renowned authors in many institutions and disciplines, this work relates the breakthroughs in knowledge in this important field to its history as well as future applications. The new edition provides readable, practical, impactful information for its many applied and fundamental disciplines. Professionals turn to this text as a reference for fundamental knowledge in their field or to inform management practices. New section on "Methods in Studying Soil Organic Matter Formation and Nutrient Dynamics" to balance the two successful chapters on microbial and physiological methodology Includes expanded information on soil interactions with organisms involved in human and plant disease Improved readability and integration for an ever-widening audience in his field Integrated concepts related to soil biota, diversity, and function allow readers in multiple disciplines to understand the complex soil biota and their function

Stressing the potential application of biochemical processes in soil to environmental biotechnology, this state-of-the-art reference considers the vital role that such biochemical processes have in the environment - emphasizing the activity of micro-organisms in soil.;An up-to-date analysis of biological reactions in soil, Volume 8 of Soil Biochemistry highlights: traditional as well as molecular and immunlogical techniques for detecting specific micro-organisms in soil; the fate of introduced genetically-modified organisms; the problem of competition by the indigenous microbial populations with the introduced organisms; the use of a white rot fungus, Phanerochaete chrysosporium, for bioremediative purposes in soil; the interaction of xenobiotics, such as pesticides, with soil organisms; generic microbial metabolism and degradation pathways; the inhibition of the nitrification process by allelochemicals released by plants; the microbial mineralization of various compounds under anaerobic conditions, explaining its importance in the global carbon cycle; the formation of soil organic matter, particularly in forest soils; and CPMAS 13C-NMR spectroscopy, a major analytical technique to determine the chemicals or chemical groups involved in the humification process.;Presenting a multidisciplinary approach to the field by internationally acclaimed scientists, Soil Biochemistry, Volume 8 is intended for professionals and students in the fields of soil science; microbiology; biochemistry; environmental science, engineering and technology; biogeochemistry; biotechnology; agronomy; plant pathology; and microbial ecology.

Traditional reliance on chemical analysis to understand the direction and extent of treatment in a bioremediation process has been found to be inadequate. Whereas the goal of bioremediation is toxicity reduction, few direct, reliable measures of this process are as yet available. Another area of intense discussion is the assessment of market forces contributing to the acceptability of bioremediation. Finally, another important component is a series of lectures and lively exchanges devoted to practical applications of different bioremediation technologies. The range of subjects covers a wide spectrum, encompassing emerging technologies as well as actual, full-scale operations. Examples discussed include landfarming, biopiling, composting, phytoremediation and mycoremediation. Each technology is explored for its utility and capability to provide desired treatment goals. Advantages and limitations of each technology are discussed. The concept of natural attenuation is also critically evaluated since in some cases where time to remediation is not a significant factor, it may be an alternative to active bioremediation operations.
