Humic substances : Nature's most versatile materials
Nature's Most Versatile Materials

Humic substances are ubiquitous in the environment. These remarkable brown biomaterials are found in animals, plants, coals, sediments, soils and water. They are crucial components of the carbon cycle and other life processes. Humic Substances: Nature's Most Versatile Materials contains a compilation of papers presented at the 2002 Humic Substances Seminar and will keep humic substances scientists up to date with the latest research.
