About this book

Proceedings of the 6th International Meeting of the International Humic Substances Society, held in Italy, 1992. Presents the results of the most recent advancements in aspects of the chemistry and biochemistry of humic substances and their applications in agriculture, industry and medicine. Also examines the interactions of humic substances with environmental inorganic and organic species and organisms in soil, aquatic and sedimentary systems.
