Experimental Basis for Sustainability and Environmental Quality
- This format is currently out of stock.
The experiments and experiences discussed in Soil Management carefully document crop production systems with well-defined boundaries. These long-term agronomic trials provide a valuable data resource that has, until now, been largely ignored by both the research community and the sustainability experts. With a rigorous definition of sustainability and this data, the sustainability of various cropping systems will be more clearly illustrated than any previous effort. Particular emphasis is given to research involving the tropics and sub-tropics.
This book is unique in providing an experimental basis for sustainable management of soil resources. It describes technological options for sustainable management of soil resources and identifies priorities for additional long-term experimentation needed in key ecoregions. Topics discussed include changes in soil processes and properties, environmental quality, soil management, soil dynamics, soil organic matter, and nutrient cycling.
Soil Management is for those who ask whether agriculture is sustainable, want to analyze or review sustainability experiments and experiences, or wish to initiate new long-term trials. It is a valuable reference on soil processes and an excellent text for courses in soil management.
