Humus, its structure and role in agriculture and environment [recurso electrónico] proceedings of the 10th Symposium Humus et Planta, held in Prague, in August 19-23, 1991

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 Content: Other Titles in this Series Page ii Front Matter Page iii Copyright page Page iv Introduction Page v J.
