This study presents a soil evaluation of the soils of la Plana, a high plateau located in semiarid central Ebro valley. MicroLEIS, a microcomputer-based mediterranean land evaluation system has been used. General land capability, forestry and agricultural suitability of the rendzic Leptosols has been assessed. In the area, land class is moderate. Although several crops are suitable, only cereals can be cultivated in rainfed conditions. Concerning forestry users, pine and olive trees have been selected as the most appropriate. Set aside land for afforestation purposes should use the most stony soils on the oriental part of La Plana.Trabajo realizado dentro del marco del convenio entre Ayuntamiento de Zaragoza y el C.S.I.C.Peer reviewed
