Variations in Soil Properties as Influenced by Land Use and Soil Depth in a Derived Savannah Ecology of Southwestern Nigeria.

Denton O.*, Ogunkunle A. O., Fademi I.

Soil physical and chemical properties are strongly influenced by soil management systems and changes in land use. The study was carried out in Iseyin LGA of Oyo state which is a derived savannah zone under four different land use types’ arable, grazing, fallow and tree crops. A total of twenty four soil samples were collected at two depths i.e. 0-1...

Characterisation and Fertility Capability Status of Alfisols Under Different Land Uses in Ogun State, South Western Nigeria

Bolarinwa Ayoola Senjobi*, Ande Olufunmilayo Titilayo, Ogunkunle A. O.

This study was designed to assess the fertility potential of agricultural soils for optimal and sustainable production. Soils under five land uses were characterized and evaluated for fertility status using Fertility Capability Classification (FCC) systems. The results showed that the morphology, physical, and chemical properties of the soils varie...

Fertility Capability Classification of Acid Sands (Soils) as Influenced by Parent Materials in Akwa Ibom State, Nigeria

B. T. Udoh*, Ogunkunle A. O., U. S. Akpan

Fertility capability classification (FCC) was carried out using data obtained from a field survey of acid sands soils in the Niger Delta area of Akwa Ibom State. The soils were studied on the basis of their parent materials, namely, coastal plain sands (CPS), beach ridge sands (BRS), sandstone/shale (SSS) and alluvial deposits (ALD). The result sho...

Spatial Variability of Micronutrients in Termite Infested Soil Formed on Nupe Sandstone in the Guinea Savanna Region of Nigeria

Jude Obi*, Ogunkunle A. O.

Soil micronutrients are nutrients required by plants in small quantity. They affect plant growth either directly or indirectly. Availability of these elements for crop growth and development may be affected by their distribution on the landscape. Variability in crop yield may indirectly be attributable to soil micronutrient variability. Termites ha...
