Humic Matter in Soil and the Environment


Book Description

The field of humic matter research has undergone drastic changes in concepts and principles since the first edition of Humic Matter in Soil and the Environment: Principles and Controversies was published more than a decade ago. Still the only book of its kind specifically addressing humic acid principles and controversies, the Second Edition presents the newest advances in humic acid science. Eleven new and rewritten chapters replace the original nine, with updated material representing modern humic acid chemistry. This includes the delineation of organic matter, humus, and humic matter. The book begins by considering organic matter as a whole, describing terrestrial and aquatic organic matter. It examines humus as a mixture of humified and nonhumified organic matter, focusing also on the importance of the nonhumified fraction—plant biopolymers in their original or slightly decomposed forms—as raw materials for formation of the humic fraction. The book then presents concepts of humic matter, referred to as humic acid, covering a range of ideas from traditional views of biopolymers to the latest concepts based on micellar, supramolecular, and nanotube chemistry. The author presents the major pathways of humification and discusses humification theories. He also examines the extraction, isolation, and fractionation of humic matter. The book reviews the chemical composition and model structures of humic acids, the chemical and spectroscopic characterization of humic substances, and the electrochemical properties of humic matter. It also addresses the agronomic, environmental, and industrial (including pharmaceutical) importance of humic matter. This revised and updated edition continues the tradition of providing comprehensive coverage of the genesis, extraction, properties, and impacts of humic matter.




Humic Matter in Soil and the Environment


Book Description

The only book to completely define and explore the genesis, extraction, properties, and impact of humic matter on agriculture, industry, and the environment, Humic Matter in Soil and the Environment delves into the issues and controversies associated with produced and natural humic compounds. It assesses the role of humic substances in medicines, fertilizers, and industrial and pharmaceutical operations, providing characteristic visible light, infrared, ESR, NMR spectra, and electron micrographs for every humic compound. Unparalleled in scope and depth, this reference examines controversies regarding humic matter as a real or false compound and identifies trends and prospects for the future.




Humic Substances


Book Description

This volume uses a molecular approach to bring the reader up to date with research into the structure and properties of these unusual materials. Agricultural and environmental scientists will find its coverage of HS use for soil remediation and enhancement and in water purification as alternatives to conventional methods invaluable.




Cation Binding by Humic Substances


Book Description

The first comprehensive account of these important environmental interactions, this book describes the binding reactions, how they can be mathematically modelled, and how this knowledge is used to interpret environmental phenomena in soils, waters and sediments. A valuable resource for advanced undergraduate and graduate students, environmental scientists, ecologists and geochemists.




Humic Substances of Soils and General Theory of Humification

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.




Fulvic and Humic Acids


Book Description

This book is about humic and fulvic acids, two types of organic substances which are increasingly becoming popular in agriculture and organic farming. In this book, the authors study and reveal their research on humic substances and the different aspects related to their formation. Other chapters include recent research on GRSP (Glomalin Related Soil Protein) and its relation to different kinds of fluorescent substances, including fulvic acid-like and humic acid-like substances. The last two chapters of the book explore humic acids and their ability to interfere in molecular ecological studies as well as the various methods one could use to measure the humic acids' concentration in soil-extracted nucleic acids. Finally, this book presents an in-depth look at the role of humic materials in the dispersion of radioactive contaminants in the environment, the latter of which are some of the most broadly circulated substances on the earth's surface, occurring in soils, rivers, lakes and seas.




Humic Substances in Terrestrial Ecosystems


Book Description

This book highlights the increasing importance of humic substances in the different scientific fields related to terrestrial ecology, soil quality conservation, and environmental chemistry. It shows that modern humic substances research is not only directed to unravel their yet ill-defined chemical structure but is successfully exploring the interconnected chemical, biological, and physical processes that maintain the ecological equilibrium of soil and ensure a sustainable agricultural production. The book will primarily be of interest to soil scientists and to ecological and environmental scientists. People in the fields of forest science, agronomy, analytical and environmental chemistry, water science, environmental engineering, and coal science will also find this publication worthy of their attention.




Humic Substances
