Abstract
Four topograghic positions and eight profiles pits identified at Andibilla plateau of Oju Local Government Area, Benue State were studied to evaluate the variation in morphological and physico-chemical properties of the soils as influenced by the topographic features (crest, upperslope, middleslope and the toeslope). The investigation reviewed that the soils were shallow to very deep ranging in depth from 6cm to 150cm. They had sandy loam surface textures underlain by sandy clay loam and clay, and were drained to poorly drained. Their chemical soil reaction were moderately to slightly acidic (5.20-6.26) with moderate to high base saturation (54-76%) and low to moderate % organic carbon content (0.04-2.44%) based on these features, the soils of the crest, (profiles 1 and 2 ) were classified as Lithic Ustorthents/Lithic Leptosols those of the upper slope as Aeric Umbric Kandiaqulfs/ Eutric Gleysols. Soils of the middle slopes (profiles 5 and 6) were classified as Kandic Paleustalfs/Eutric Nitosols while those of the toeslope (profiles 7 and 8) were grouped as Typic Plinthaqualfs/Plinthic Gleysols. Perennial crops were recommended for the soils of the crest and upper slope while the best land use for these of middle and toeslope are arable crops and water loving crops respectively.
