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.

Present in soil and water, humic substances are the most widespread organic compounds, naturally occurring from a physical, chemical, and microbiological transformation of biomolecules. They represent about 25% of the total organic carbon on the Earth and comprise up to 75% of the dissolved organic carbon in water, making them important for multiple environmental processes in both soil and aquatic systems. Despite many decades of extensive study, the formation mechanisms of humic substances are still a subject of discussion and controversy. This book examines the dynamics of humic substances, their physicochemical and biological properties, and methods for their extraction and characterization. The book also sheds light on recent advances and applications of humic substances in agriculture, environment, industry, and medicine.

Humic substances occur in all kinds of aquatic systems, but are particularly important in northern, coniferous areas. They strongly modify the aquatic ecosystems and also constitute a major problem in the drinking water supply. This volume covers all aspects of aquatic humic substances, from their origin and chemical properties, their effects on light and nutrient regimes and biogeochemical cycling, to their role regarding organisms, productivity and food web organization from bacteria to fish. Special emphasis is paid to carbon cycling and food web organization in humic lakes, but aspects of marine carbon cycling related to humus are treated as well.

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 substances, the remarkable brown biomaterials in animals, coals, plants, sediments, soils and waters, are crucial components of the carbon cycle and other life processes. Thus greater knowledge and understanding of these versatile materials is of great importance to the productivity, health and safety of the world's ecosystems, humans, land and water. Presenting the best and most recent research in this important area, this book focuses on the molecular and chemical aspects of humic substances, with sophisticated analytical, chemical and physical techniques providing vital information. Areas covered include spectroscopy, modelling, mobility, properties and analysis of humic substances. Humic Substances: Structures, Models and Functions will be welcomed by researchers and professionals in academia, industry and government agencies worldwide, particularly where the science of humic substances finds applications, such as environmental remediation and sustainable agriculture.
