Nine years of conservation agriculture-based cropping systems research in eastern Africa to soil degradation and mitigate effects of climate change Universiteit Gent
In Ethiopia, repeated plowing, complete removal of crop residues at harvest and aftermath grazing of crop fi elds have reduced the biomass return to the soil and aggravated cropland degradation. Conservation Agriculture (CA)-based cropping systems may reduce runoff and soil erosion, and improve soil quality and crop productivity. Thus, a long-term tillage experiment has been carried out (2005 to 20123) on a Vertisol to quantify - among others - ...
