A study of a soil profile conducted to investigate the characteristics of vertisols at the 10 ILCA research sites in Ethiopia. Describes the study sites with regard to activity climate and parent material. Presents the pedon description, physical and chemical analysis of each soil as well as the ...

The literature on technology adoption distinguishes between diffusion (generally viewed as a dynamic process) and adoption (usually seen as static and specific to a point in time). Consistent with this, empirical studies on agricultural technology adoption generally divide a population into adopt...

In the Ethiopian highlands, where integrated crop and livestock production takes place, the inadequate supply, in both quantity and quality of feeds during the year is a major constraint. Native pastures and crop residues are the major feed sources, but their quality is often poor. Integration of...

Livestock and crop-livestock systems are usually more complex than single cropping systems and are thus more difficult to "improve". The International Livestock Centre for Africa outlines experiences with systems research in projects in Nigeria and in the Ethiopian highlands.

Land-use intensification in the East-African highland zone is required for meeting food and feed demands from the rising human and animal populations. A single crop of wheat has been a traditional practice for the 8 Mha of Vertisols in the Ethiopian highlands with both grain and residues finding ...
