Deep Tillage Improves Degraded Soils in the (Sub) Humid Ethiopian Highlands

Phosphorus forms and dynamics as influenced by land use changes in the sub-humid Ethiopian highlands

Ž . In undisturbed tropical forest ecosystems, the phosphorus P cycle is essentially AclosedB with minimal short-term losses or gains of P. The forms and dynamics of soil P, however, can be greatly affected by land use changes, which often involve changes in vegetation cover, biomass production and nutrient cycling in the ecosystem. Sequential extraction and P nuclear magnetic Ž . resonance NMR...

Are Runoff Processes Ecologically or Topographically Driven in the (Sub) Humid Ethiopian Highlands? The Case of the Maybar Watershed

Understanding the basic runoff processes in the Ethiopian highlands is vital for effective management and utilization of water resources and soil conservation planning. An important question for judging effectiveness of conservation practices is whether runoff is affected by ecology (mainly type of crop) or topography (landscape). A study was conducted in the 113 ha watershed of Maybar, located...

Sulfur fractions in particle-size separates of the sub-humid Ethiopian highlands as influenced by land use changes

Extensive deforestation of natural forests in the Ethiopian highlands and their conversion to low-input agriculture and plantations have caused severe soil degradation and significant changes in the ecosystem. We investigated the influence of land use changes on the amount, form and Ž . distribution of sulfur S in bulk soils and size separates of the sub-humid highlands of southern Ž . Ethiopia...
