Assessment of Land Use Pattern and Land Form on Selected Physico-Chemical Properties of Soils Developed on Basement Complex-Sedimentary Transitional Zone of South Western Nigeria

The effects of cropping practices and soil management on the properties of basement complex- sedimentary transitional zone soils in South Western Nigeria was assessed using soil samples from the pedogenic horizons of ten profile pits dug on two land-use systems (subsistence and experimental farms) and two toposequence. The land use significantly (P<0.01) affected soil pH (in KCl) , Fe and Cu (P<0.05). Topography had significant ((P<0.01) effects on the particle size distribution, Fe, Na (P<0.001) and Cu while soil depth had significant (P<0.001) effects on soil particle size distribution, pH, organic carbon (OC), P, Cu, Zn, Mn (P<0.01), Mg and Fe (P<0.05) contents of the soil studed.
