Book Description
Despite the large number of papers and books published on soil organic matter (humus), our knowledge of the subject is still very limited, as is our knowledge of humic acid. The author of this book began to study humus at the end of the 1940s and continued until 1984 when he retired from Nagoya University. With the intention of establishing a systematic understanding of soil organic matter, he has compiled facts and a discussion of humus based on his extensive experimental results during the past 40 years.In this book, humic acids are classified into A, B, Rp and P types, based on their optical properties. The elementary composition and other chemical properties of humic acid types are shown to be regularly different from each other. A new method for humus composition analysis applied to various kinds of soils in Japan and several other countries indicates that the diversity of humus compositions of soils is systematically understandable. These findings lead the author to novel theories on the chemical configuration and formation of humic acids and humic substances. Diagenesis of humus under terrestrial conditions is illustrated as to the buried humic horizons of Black soil (Andosol).The book will be useful not only to soil scientists and agronomists but also to geochemists, oceanographers, limnologists, water scientists, biologists and chemists who are dealing with organic matter in terrestrial, aquatic, and sedimentary environments.

Book Description
Comprehensive, up-to-date coverage of the basics of soil chemistry Although only a meter in depth over the earth's surface, soil is key to sustaining life-affecting air and water quality, the growth of plants and crops, and the health of the entire planet. The complex interplay among organic and inorganic solids, air, water, microorganisms, and plant roots in soil is the subject of Soil Chemistry, a reference pivotal to understanding soil processes and problems. Thoroughly reorganized for ease of use, this updated Third Edition of Soil Chemistry summarizes the important research and fundamental knowledge in the field in a single, readily usable text, including: Soil-ion interactions Biogeological cycles and pollution Water and soil solutions Oxidation and reduction Inorganic solid phase and organic matter in soil Weathering and soil development Cation retention (exchange) Anion and molecular retention Acid and salt-affected soils New to the Third Edition is an enhanced emphasis on soil solution chemistry and expanded coverage of phosphate chemistry and the chemical principles of the aqueous phase. At the same time, the book has retained the clear examination of the fundamentals of the science of soil that has distinguished earlier editions. Complete with SI units and end-of-chapter study questions, Soil Chemistry is an excellent introductory resource for students studying this crucial topic.

Book Description
An up-to-date resource on natural nonliving organic matter Bringing together world-renowned researchers to explore natural nonliving organic matter (NOM) and its chemical, biological, and ecological importance, Biophysico-Chemical Processes Involving Natural Nonliving Organic Matter in Environmental Systems offers an integrated view of the dynamics and processes of NOM. This multidisciplinary approach allows for a comprehensive treatment encompassing all the formation processes, properties, reactions, environments, and analytical techniques associated with the latest research on NOM. After briefly outlining the historical background, current ideas, and future prospects of the study of NOM, the coverage examines: The formation mechanisms of humic substances Organo-clay complexes The effects of organic matter amendment Black carbon in the environment Carbon sequestration and dynamics in soil Biological activities of humic substances Dissolved organic matter Humic substances in the rhizosphere Marine organic matter Organic matter in atmospheric particles In addition to the above topics, the coverage includes such relevant analytical techniques as separation technology; analytical pyrolysis and soft-ionization mass spectrometry; nuclear magnetic resonance; EPR, FTIR, Raman, UV-visible adsorption, fluorescence, and X-ray spectroscopies; and thermal analysis. Hundreds of illustrations and photographs further illuminate the various chapters. An essential resource for both students and professionals in environmental science, environmental engineering, water science, soil science, geology, and environmental chemistry, Biophysico-Chemical Processes Involving Natural Nonliving Organic Matter in Environmental Systems provides a unique combination of the latest discoveries, developments, and future prospects in this field.

Book Description
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
