The field of humic matter research has undergone drastic changes in concepts and principles, and a second edition is now warranted to communicate these advances. This revised and updated edition continues the tradition of providing comprehensive coverage of the genesis, extraction, properties, and impacts of humic matter on agriculture, industry, and the environment. Chapters examine organic matter; present concepts of humus versus humic matter; and explore the nature and distribution, chemical composition, characterization, electrochemical properties, agronomic and industrial applications, and medicinal and pharmaceutical applications of humic substances.
