Effects of Land Use on Soil Micronutrients Status in Ughoton Community Ovia North East, Edo State, Nigeria.

P.O. Oviasogie^*, Awanlemien B. E., Ikyaahemba P. T.

The study was conducted to assess the effects of different land use practices on soil micronutrients in 18 soil samples collected at 0-15 cm and 15-30 cm depth respectively from three land use types (Cassava field, Oil palm and Banana plantation) and analyzed for physico-chemical properties and selected micronutrients (Zn, Cu, Fe and Mn) using standard laboratory methods. The results showed that O...

Prediction of Saturated Hydraulic Conductivity Using Soil Texture and Organic Carbon Under Different Land Use Types

Onasanya, O. O^*, F.K. Salako, AJIBOYE G. A., Busari M. A.

The aim of this study is to develop models for saturated hydraulic conductivity (Ks) in soils under different land use types in a tropical environment. The regression models were developed using the soil particle size fraction and organic carbon contents.The results indicated that the sand, clay and organic carbon content of the soils were sufficient in predicting the Ks. Also, there was a signifi...

Forms of Primary Nutrient Elements in Soils Overlying Contrasting Parent Materials in South - Eastern Nigeria

AHUKAEMERE C.M.^*, Bethel Ugochukwu Uzoho, Ndukwu, B., Onwudike S,U., Okoli N.H., Irokwe I. F.

Appropriate management of soil fertility should rely upon sound knowledge of the nutrients reserve and their availability. This is only possible if there is adequate information on the influence of parent material on the dynamics and availability of these nutrient elements. Research was carried out in 2014 at three locations underlain by three different parent materials namely Basalt (Ikom in Cros...

Distribution of Forms of Potassium in Soils Cultivated to Shea (vitellaria Paradoxa C.f. Gaertn) Trees at Bida, Niger State, Nigeria

OSAYANDE P.E.^*, P.O. Oviasogie, Orhue, Ehi Robert, Udoh, J. J

The distribution of potassium forms was studied at Bida, Niger state as part of the Shea butter tree domestication effort of the Nigerian Institute for Oil Palm Research. Soil samples were obtained with the aid of a soil auger at 0-15 and 15-30 cm. The soil samples were air dried, sieved with a 2 mm sieve and analyzed for some physical, chemical and potassium forms using standard methods. Results ...

Potential Impacts of Natural Gas Pipeline Construction and Operation on Land/Soil Quality in South Eastern Nigeria

Akinbola G. E.^*, Orimoloye J. R.

The quest to make available, cheaper, cleaner, more efficient and more reliable sources of energy and feedstock for industrial and domestic uses,in Aba Owerrinta axis of Abia State, Southeastern Nigeria in a developmental process cannot be over emphasized. This has necessitated the construction and installation of a 12” diameter natural gas pipeline with a l00 m wide right of way for a distance of...

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

Denton O.^*, Ogunkunle, A, 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. 0-15cm and 15-30cm, from the study area using the clu...
