Three pedons were identified and described on representative landscapes at three different locations in Habro highlands, eastern Ethiopia, which produce one of the best quality coffee in the country. The study was conducted to investigate the morph9logical properties and physic-chemical characteristics of the dominant soils in the area. Surface soils of the three locations (Bitania, Deffo and Micheta) had pH of 6.2, 6.8 and 5.9, respectively. Texture of the surface soils was sandy clay loam and colour varied from veryt dark brown at Bitania to dark reddish brown to reddish brown at Deffo and Micheta, respectively. Survace horizons had fine granular structures. Organic carbon and total N decreased with depth in all the three pedons. Exchangeable Ca was the dominant cation in all soil types. The cation exchange capacity (CEC) and percent base saturation (BS) of Deffo and Micheta soils were relatively higher in the surface horizons than in the lower depths. The soils are tentatively classified as Leptosol at Bitania and Nitosol at Micheta and Deffo locations.
