This volume presents the proceedings of the 10th international symposium Humus et Planta held in Prague in August 19-23, 1991. The main topics of this book are devoted to the recent advances in fundamental, as well as applied research of humic substances, the most abundant of the naturally occuring macromolecules of nature, the understanding of their nature and how they react and interact in their natural environments. Texts are included on the structure, physical and chemical properties of humic substances; the relationships among humus, soil properties and fertilit.
