to understand the complex ecological role of microbes in the edification
and function of soils and have historically influenced the specific approach
of soil microbiology as a scientific discipline. The second chapter of this
introductory section reviews the diversity of soil microorganisms with
regard to classical systematics and the differentiation into functional groups
or inhabitants of functional domains in soils.

(Deutsche Forschungsgemeinschaft) in different research projects
dealing with soil biological aspects (especially grant numbers Bu 941–1/1–3
and Bu 941–2/1–2) is gratefully acknowledged. I am indebted to my friend
Professor Ajit Varma (Jawaharlal Nehru University, New Delhi, India) for
his collaboration in this book project. Finally, I would like to dedicate this
chapter to my mentor, Prof. Dr. Jean Charles Munch (GSF München, Germany),
who not only provided guidance during my habilitation, but also
aroused my interest in soil biology.
