To generate needed information for fertility of the University's agro-pastoral farm on a large scale, three representative soil profile pits (P1, P2 and P3) were carried out, and two fixed soil layers depths (0–20, 20–40 cm) were taken (three replicates). 18 composite soil samples were airdried and passed through a 2-mm sieve prior laboratory analysis. Eutric Ferralsol-P1 (14.41 ha), Eutric Cambisol-P2 (6.53 ha) and Dystric Gleysol-P3 (8.82 ha) were found using CPCS and FAO's Guidelines for Soil. Soil reaction was strongly too slightly acid (5.0 to 6.5). Total nitrogen (TN), organic carbon (OC) and available phosphorus (Av. P) decreased with depth. OC, though being low (0.5 to 1 g.kg), whereas Tot.N was medium (0.06 to 0.16 g.kg), and, Av. P was rated as medium to high (21.0 to 47.33 mg.kg). Cation exchange capacity ranged from medium (5.12 6.68 cmol.kg ) to high (15.1 18.2 cmol.kg). On the basis of silt/clay ratios, degree of weathering decreased from Dystric GleysolP3 > Eutric Ferralsol-P1 > Eutric Cambisol-P2. The soils were rated as having medium fertility and P3 was regarded as generally good agro-productive characteristics for savannah agriculture. Specific land management and cropping systems were recommended for sustainable utilization of soils.
