It has long been recognized that soil organic matter is the key to
soil fertility. As a nutrient store it gradually provides essential
elements which the soil cannot retain for long in inorganic form.
It buffers growing plants against sudden changes in their chemical
environment and preserves moisture in times of drought. It keeps
the soil in a friable, easily penetrated physical condition,
well-aerated and free draining, providing young seedlings with an
excellent medium for growth. But it has another property, the
nature and extent of which have been the subject of argu ment and
controversy ever since scientists began to study the soil, and that
is its ability to affect growth directly, other than by providing
nutrient elements. Any one wishing to learn about these effects has
been faced with a daunting mass of literature, some confusing,
often contradictory, and spread through a multitude of journals.
Individual aspects have been covered from time to time in reviews
but there has obviously been a need for a modern authoritative text
book dealing with the many facets of this subject, so the
publication of this volume is timely. The editors and authors are
all specialists in their fields, fully familiar with the com plex
nature of soil organic matter and with the particular difficulties
arising in any study of its properties. Where controversies exist
they have presented all sides of the argument and have highlighted
areas where further work is badly needed."
