Beschreibung:
Dr. Bruno Glaser is Assistant Professor at the Institute of Soil Science and Soil Geography at the University of Bayreuth. For over seven years he has been conducting Amazonian dark earth research from a soil science perspective including soil fertility, sustainability, and archaeology aspects.
The regenerative qualities identified in prehistoric, anthropogenic Amazonian dark earths suggest that notoriously infertile tropical soils can be greatly improved. Soil enhancement practices by ancient Amerindians allowed them to cultivate the land intensively, without needing to continually clear new fields from forest. As increasing populations place ever greater pressure on tropical forests, this legacy of rich, 'living' soils warrants further study in the search for high-yield, land-intensive, yet sustainable forms of management. The international group of contributors to this volume provides a variety of stances centering on aspects of the origin, distribution, variability, persistence, and use of Amazonian dark earths.
First book ever to address specifically the topic of prehistoric Amazonian dark earths
