The extraordinary fertility of manmade Terra Preta soils in the Brazilian Amazon provided the incentive to study the effects of soil charcoal amendments on soil fertility, nutrient cycling, and soil biology. The existence of Terra Preta suggests that tropical soils, which are notorious for being infertile, can be greatly improved. The agricultural produces charcoal out of fallow vegetation instead of converting it to carbon dioxide through burning. Slash and char improves soil quality by transferring organic carbon into recalcitrant soil organic matter pools. This newly described agricultural practice has important implications for the earth's carbon budget and sustainability in tropical agriculture.
Amazonian soils are almost universally thought of as extremely forbidding. However, it is now clear that complex societies with large, sedentary populations were present for over a millennium before European contact. Associated with these are tracts of anomalously fertile, dark soils termed ‘terra preta’ or dark earths. These soils are presently an important agricultural resource within Amazonia and provide a model for developing long-term future sustainability of food production in tropical environments. The late Dutch soil scientist Wim Sombroek (1934-2003) was instrumental in bringing the significance of these soils to the attention of the world over four decades ago. Wim saw not only...

Explores how, over centuries, Amazonian people and their cultures have interacted with rainforests William Balée is a world-renowned expert on the cultural and historical ecology of the Amazon basin. His new collection, Sowing the Forest, is a companion volume to the award-winning Cultural Forests of the Amazon, published in 2013. Sowing the Forest engages in depth with how, over centuries, Amazonian people and their cultures have interacted with rainforests, making the landscapes of palm forests and other kinds of forests, and how these and related forests have fed back into the vocabulary and behavior of current indigenous occupants of the remotest parts of the vast hinterlands. The book ...
Die peregrinatio academica, die Migration von Studenten aus der hochschularmen ostlichen Halfte Europas, stellte vom Mittelalter bis ins 20. Jahrhundert eine grundlegende Form der akademischen Ausbildung dar. Dies trifft besonders fur das territorial und konfessionell geteilte Konigreich Ungarn zu, wo die fruheste dauerhafte Grundung einer Universitat erst im Jahre 1635 durch den Jesuitenorden erfolgte. Das ungarische Bildungssystem war so Jahrhunderte lang auf die europaischen Institutionen angewiesen. Die Universitaten und Hohen Schulen im Heiligen Romischen Reich deutscher Nation gehorten seit der Ausbreitung der Reformation zu den Bildungseinrichtungen, die von den Studenten aus Ungarn a...
