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 ...

The properties of humic substances (HSs) in plants, soils and sediments regulate the environment and affect all aspects of like, yet they are only very imprecisely understood. This volume presents work on HSs including new instruments and techniques being developed to throw more light on their structure and relationship to macro- and micro-scopic properties.

This volume uses a molecular approach to bring the reader up to date with the latest 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.

Reporting on front-line research into these natural materials, this volume focuses on the use of chemical and physical methodology in seeking an explanation of the structures of HSs and their relation to their microscopic properties.
