Pasture Degradation Project
Woody enrichment of degraded smallholder pastures–
options to avoid, to renovate, and to quantify degraded pastures in the north-eastern Amazon, Brazil
Cooperation partner: Embrapa Amazônia Oriental, Belém
- Soil improvement and forage production of Cratylia argentea and Flemingia macrophylla under smallholder management, large-scale holder and intensive pasture management.
- Soil improving grass-capoeira-legume pasture with more frequent and intensive slashing and sheep as partially browsing grazers.
- Low-Input geoecological services of domesticated animals (cattle, pigs) for cheap recuperation of biologically degraded pastures.
- Soil fertility enrichment and forage grass production of burning, mulching or ploughing of an agronomically degraded pasture.
- Quantification of different degradation stages through capoeira encroachment on pastures by using Quickbird and Landsat-TM satellite images (thesis of Timo Krummel)
- Cafeteria-trail with ten woody species for soil improvement and as forage supplements for grazing cattle.
