Humic Substances Seminar 1998 : Northeastern University)
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 instruments and techniques being developed to throw more light on their structure and relationship to macro- and micro-scopic properties.
