Effect of Oil Palm Cultivation on the Micronutrient Status of Soils in a Coastal Plain Sands Area of Akwa Ibom State, Nigeria

Chukwu E. D*, B. T. Udoh, Nnabuihe, E, Okoli N. H, Osisi A. F

High levels of micronutrients may cause metabolic disorders and become growth inhibitors to most plant species. Therefore, the study assessed the levels of micronutrients in soils under oil palm cultivation in a coastal plain sands area of Akwa Ibom State, Nigeria. Three oil palm blocks of varying ages, l7 years (B-17), 39 years (B-39) and 57 years...

Classification and Fertility Status of Soils on Slopes of Varying Orientations in Umuahia Area of Abia State, Nigeria

Aliba, V.O.*, Onweremadu E. U, Aririguzo, B. N, Okoli N. H

The slope orientation and position of toposequence influence soil properties along the landscape. The study classified and evaluated the fertility status of soils on slopes of varying orientations in Umudike (East-lying Toposequence) and Itu (West-lying Toposequence) located in Olokoro Umuahia, Abia State southeastern Nigeria. Transect soil samplin...

Status of Available Micronutrients in Soil Profiles of Different Parent Materials in Imo State, Southeastern, Nigeria

Okoli N. H*, Bethel Ugochukwu Uzoho, Onweremadu E. U, Ahukaemere C. M., Osisi A. F, Aliba E.O.

The status of available Zn, Cu, Ni and Fe was studied in four representative soil profiles of different parent materials (Coastal Plain Sands, Alluvium, Falsebedded Sandstones and Imo Clay Shale) in Imo State, Southeastern Nigeria. Sample collection was guided by horizon differentiation. Available Zn, Cu, Ni and Fe were evaluated using double acid ...
