This text explains the difference between the variable charge soils of tropical and subtropical regions, and the constant charge soils of temperate regions. It focuses on the chemical properties of the variable charge soils - properties which have an important bearing on soil management practices.

This book, based on research carried out at the Academia Sinica over the past 30 years, explains the basic difference between the variable charge soils of tropical and subtropical regions, and the constant charge soils of temperate regions. It will focus on the chemical properties of the variable charge soils--properties which have important bearing on soil management practices, including maximizing soil productivity and combating soil pollution.

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

Soils are one of the world's most important resources, and their protection, maintenance, and improvement is critical to the continuance of life on earth. Soil Fertility, Second Edition, offers thorough coverage of the fertility, composition, properties, and management of soils. This book carries on the tradition of excellence established by authors Henry Foth and Boyd Ellis, leading soil scientists whose previous books in this field have become multi-edition classics. The Second Edition of Soil Fertility has been significantly expanded to include more information on mineralogy, while keeping the thorough coverage of essential topics. The book presents soils as dynamic, constantly changing bodies, and relates soil fertility and management to the mineralogy of their origin. Four new chapters offer updated information on soil charge properties, ion adsorption, exchange and fixation, and soil reaction. There is also a far greater emphasis on environmental issues, reflecting the increasing importance of environmental concerns to agronomists and soil scientists today.

"Upholding the high standard of quality set by the previous edition, this two-volume second edition offers a vast array of recent peer-reviewed articles. It showcases research and practices with added sections on ISTIC-World Soil Information, root growth and agricultural management, nitrate leaching management, podzols, paramos soils, water repellant soils, rare earth elements, and more. With hundreds of entries covering tillage, irrigation, erosion control, ground water, and soil degradation, the book offers quick access to all branches of soil science, from mineralology and physics, to soil management, restoration, and global warming."--Publisher's website.

In Environmental Soil and Water Chemistry, leading soil and water authority V. P. Evangelou presents a complete overview of the principles and applications of soil science, addressing the subject by viewing the interactions between soil and water as a basis for understanding the nature, extent, and treatment of polluted soil and water. The text opens with a discussion of principles - the fundamental tenets of chemistry needed to understand soil and water quality and treatment of polluted resources - and continues with a look at applications for the control and treatment of soil and water. This text is suitable for advanced undergraduates and beginning graduate students.

As the author states in his Preface, this book is written at a time when scientific and lay communities recognize that knowledge of environmental chemistry is fundamental in understanding and predicting the fate of pollutants in soils and waters, and in making sound decisions about remediation of contaminated soils. Environmental Soil Chemistry presents the fundamental concepts of soil science and applies them to environmentally significant reactions in soil. Clearly and concisely written for undergraduate and beginning graduate students of soil science, the book is likewise accessible to all students and professionals of environmental engineering and science. Chapters cover background information useful to students new to the discipline, including the chemistry of inorganic and organic soil components, soilacidity and salinity, and ion exchange and redox phenomena. However, discussion also extends to sorption/desorption, oxidation-reduction of metals and organic chemicals, rates of pollutant reactions as well as technologies for remediating contaminated soils. Supplementary reading lists, sample problems, and extensive tables and figures make this textbook accessible to readers. - Provides students with both sound contemporary training in the basics of soil chemistry and applications to real-world environmental concerns - Timely and comprehensive discussion of important concepts including: Sorption/desorption, Oxidation-reduction of metals and organics, Effects of acidic deposition and salinity on contaminant reactions - Boxed sections focus on sample problems and explanations of key terms and parameters - Extensive tables on elemental composition of soils, rocks and sediments, pesticide classes, inorganic minerals, and methods of decontaminating soils - Clearly written for all students and professionals in environmental science and environmental engineering as well as soil science

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. 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. 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

Long-awaited second edition of classic textbook, brought completely up to date, for courses on tropical soils, and reference for scientists and professionals.
