Book Description
Excerpt from Some Effects of Steam Sterilization on Physical, Chemical and Biological Relationships of Soils The study of the complicated inter-relationships of soil micro-organisms (9) and plant diseases, and of soil micro-organisms and soil fertility, may be simplified by first studying the relationships of a few known organisms on sterilized soil devoid of its enormous population.

Book Description
Excerpt from The Chemistry of Steam-Heated Soils The subject of the effect which heat has upon soils 13 rather promi nently before agricultural investigators at the present time. This subject has received Increasing attention during the last decade, par ticularly from the point of view of sterilization and partial steri lization. There has been much valuable information obtained along the biological lines concerned; also much speculation in this regard without due consideration of the chemical and physical changes in volved, owing largely to the fact that these were not known or but imperfectly understood. The biological factors can not and should not be ignored, but it must be remembered that they are only of sig nificance or interest in the light Of the biochemical changes which they produce in the soil. Moreover, any biochemical changes produced in the soil through other means, be they cultural or by the addition of manures and fertilizers or by the influence of steam heating, in turn affect-the biological activities. The chemistry, therefore, of the soil both before and after heating in, sterilization work becomes of the greatest significance to the biological worker.

Book Description
Sediment contamination is a widespread environmental problem that can potentially pose a threat to a variety of aquatic ecosystems. The sediment test methods in this manual will be used by The United States Environmental Protection Agency (USEPA) to make decisions under a range of statutory authorities concerning such issues as: dredged material disposal, registration of pesticides and toxic substances, superfound site assessment, and assessment and cleanup of hazardous waste treatment, storage, and disposal facilities. The use of uniform sediment testing procedures by USEPA programs is expected to increase data accuracy and precision, facilitate test replication, increase the comparative value of test results, and ultimately, increase the efficiency of regulatory processes requiring sediment tests.

Book Description
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
