Opis

This work is intended for soil scientists, hydrologists, geologists, agronomists and geographers in the fields of soil conservation, applied geo-sciences, agriculture and forestry. It: describes methods of assessment of soil degradation by different processes in relation to their impact on agronomic productivity and environmental quality; addresses the agronomic and economic impacts of soil degradation; considers research and development priorities; and presents material suitable for use by students of soil science, agronomy, and geography or natural resources management.
