Forest soils of Ethiopian highlands: their characteristics in relation to site history: studies based on stable isotopes

Zewdu Eshetu (Alemaya Agricultural University, Dire Dawa (Ethiopia))
Isotopic composition and nutrient contents of soils in forests, pastures and cultivated lands were studied in Menagesha and Wendo-Genet, Ethiopia, in order to determine the effects of land use changes on soil organic matter, the N cycle and the supply of other nutrients. The studies show that the approach to combine stable isotopes with nutrient elements is especially useful when studying the chemical properties of forest soils in relation to site history. They also show that productive forests with a high soil organic matter content can be establish on fairly steep slopes in the Ethiopian highlands.
