Abstract

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 fertility; the biotransformations of
organic substances in the soil; the relationships between
humic substances and plants and the interactions of humus and
xenobiotic substances. This book presents recent knowledge of
the complicated and challenging humic substances. It will be
of interest not only to scientist, but also to University
teachers and students of agricultural and environmental
sciences.
