Overview

Environmental considerations are playing an increasingly important role in determining management strategies for soil and land since many important environmental issues involve aspects of the biology of the soil. The first part of the book provides an introduction to soils, its inhabitants and their activities. The second part covers the influence of man on the natural cycles of soil. Topics such as acid rain and nitrogen fertilizers are considered alongside pesticides and genetically modified organisms. A new final chapter has been added which considers how the population can apply the concept of sustainability to issues such as global climate change and farming systems.
