Abstract
The soil profile samples that are present in upper slopes of the Palamaner agricultural division are evaluated to know the production potential of the study area. The soils have moderate slope and are affected by erosion. Besides, soils have excessive drainage limitation. Geologically, soils are developed on the quartz-migmatite gneiss complex. All the soils are studied for morphological, physico-chemical and chemical properties. The results shown that, soils are slightly acidic to neutral in soil reaction (pH), non saline (EC), moderately deep to deep (90-135 cm) in depth. The texture of soils varied from moderately well drained with no erosion to severe erosion. The soils are placed under IVes land capability class. The actual productivity and the potential productivity are calculated; the maximum potential productivity was 81.23 and the crop improvement factor was 1.59.
