Book Description
Soil and Environmental Chemistry, Second Edition, presents key aspects of soil chemistry in environmental science, including dose responses, risk characterization, and practical applications of calculations using spreadsheets. The book offers a holistic, practical approach to the application of environmental chemistry to soil science and is designed to equip the reader with the chemistry knowledge and problem-solving skills necessary to validate and interpret data. This updated edition features significantly revised chapters, averaging almost a 50% revision overall, including some reordering of chapters. All new problem sets and solutions are found at the end of each chapter, and linked to a companion site that reflects advances in the field, including expanded coverage of such topics as sample collection, soil moisture, soil carbon cycle models, water chemistry simulation, alkalinity, and redox reactions. There is also additional pedagogy, including key term and real-world scenarios. This book is a must-have reference for researchers and practitioners in environmental and soil sciences, as well as intermediate and advanced students in soil science and/or environmental chemistry. - Includes additional pedagogy, such as key terms and real-world scenarios - Supplemented by over 100 spreadsheets to migrate readers from calculator-based to spreadsheet-based problem-solving that are directly linked from the text - Includes example problems and solutions to enhance understanding - Significantly revised chapters link to a companion site that reflects advances in the field, including expanded coverage of such topics as sample collection, soil moisture, soil carbon cycle models, water chemistry simulation, alkalinity, and redox reactions

Book Description
The papers in this volume cover micromorphological studies of a wide variety of topics, at various scales from ultramicro- to mesoscopic. Topics included are:soil management; soil structure; surface crusts; hardpans and cemented layers; soil biota; soil genesis; hydromorphic soils; paleosols; archeology; and general pedology. The range of papers reflects the growing use of soil micromorphology in understanding soil problems in land-use and the increasing use of quantitative techniques, together with more traditional applications in pedology. The book is well illustrated with micrographs and contains both author and keyword indices.

Book Description
"Food and Population in a Northeast Thai Village is a remarkably thorough baseline study of the interrelationship between demographic change, land and agricultural production in what must be one of the most intensively studied village communities in Asia, Ban Don Daeng, which lies a few kilometres from the North-East Thai regional urban centre of Khon Kaen." —Journal of Southeast Asian Studies (30:01, March 1999)

Book Description
China contributes a large part to rice production, one of the most important crops in the world. It is estimated that in China rice constitutes about half of the total food production, covering an area of about 30 % of \08 hectares of cultivated land of the whole country. Owing to the peculiar water regime, paddy soils possess quite different properties physically, chemically and biologically as compared with those of upland soils. Such properties have a conspicuous effect on fertility and management practice of paddy field. For the purpose of summing up the past work and opening up new prospects, a "Symposium on Paddy Soils" was organized under the auspices of Academia Sinica, held on October 19-24, 1980 in Nanjing, which was followed by a seven-day paddy soil excursion in the lower Changjiang Delta. In addition to 120 Chinese soil scientists, 56 guests coming from America, Asia, Europe and Oceania attended the symposium on invitation. A total of 110 papers were presented either orally or by poster. All these are collected and published in the present proceedings which we hope may be helpful to the scientific exchanges between soil scientists of China and other countries.
