The main reason was that the Czech Republic is rich in deposits of various raw materials potentially suitable for the production of humic substances. Main goals of the investigations were the selection of raw materials, as well as the determination of their chemical and physical properties. This book presents the results of these extensive investigation. Table of Contents: Preface Chapter 1.
