Soil Acidity Problems And Comparison Of Lime Requirement Determination Methods In Different Land Uses Systems The Case Of Fagetalekoma Woreda Awi Zone

Soil acidity is one of chemical soil degradation problems which affect productivity of the soilrnin Ethiopian highlands. The purpose of this research was to assess the status of soil acidity inrndifferent land uses systems and to compare different lime requirement determination methodsrnin Fagtalokoma woreda, Awi Zone. The different land use systems were cultivated land,rnbackyard, grazing land and the natural forest. Composite soil samples were collected alongrntransects in each of the land use systems and analyzed in laboratory. Lime requirement wasrndetermined using acid saturation and SMP buffer solution methods. The results indicatedrnthat cultivated land and grazing land were strongly acidic (pH
