Pedological Characterization and Classification of Selected Soils of Morogoro and Mbeya Regions of Tanzania

This study was done in Morogoro and Mbeya regions of Tanzania to classify characterize their respective soils. Representative pedons (SUARAT-P1 UYOLE-P1) were dug described using FAO guidelines clarifying morphological features, physico-chemical properties genesis. The representative geo-referenced Global Positioning System (GPS) receiver. A total nine (9) genetic soil horizons identified from both sites samples each horizon collected for physical chemical analyses. Soils very deep topsoil moist colors ranged hue 7.5YR 10YR with chroma less than 3 SUARAT-P1 UYOLE-P1 pedons. Soil structure strong fine crumbs topsoils medium coarse sub-angular blocks subsoils while had weak subsoils. sandy clay (SC) texture subsoil loam (SL) sand (SCL) subsoil. reaction slightly acid strongly (pH 6.54 - 4.46) whereas neutral 6.35 – 7.32). Organic carbon low (0.12- 0.95%) (0.47 1.5%) UYOLE-P1. Nitrogen levels (0.05 0.12%) available P (0.30 mg kg-1) (8.55 CEC ranging 12.4 23.2 cmol(c) kg-1, high (15 34 kg-1). In SUARAT-P1, BS (> 50%) (< the registered throughout its profile depth. As diagnostic classification, an ochric epipedon overlying a kandic horizon classified according USDA Taxonomy as Typic Kandiustults, over cambic named Andic Dystrudepts corresponding respectively Haplic Lixisols Eutric Andic Cambisols WRB Resources. results have indicated that, studied soils are fertile possible reconstitution through land crop managements which include but not limited no-tilling or conservation tillage, manuring proper fertilizer application; residue retention, fallowing, liming potential buffering pH especially at rotation intercropping leguminous crops.
