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...

Influence of Oil Palm Cultivation on Topsoil Properties in Nigerian Institute for Oil Palm Research, Akwa Ibom State

Chukwu E. D*, B. T. Udoh, Afangide, A. I, Osisi A. F

The thin layer of soil covering the surface of the earth represents the difference between survival and extinction for most land-based life. Four oil palm blocks of varying ages: 57 years (B-57), 39 years (B-39), 17 years (B-17), and no oil palm block (B-0), which served as the control, were identified and used for the study. The result showed that...

Kinetics of Phosphorus Sorption in Selected Soils of Southeastern Nigeria

Azu, Donatus E.O*, V.E. Osodeke, Onwuka, M. I, Osisi A. F

This study investigated the phosphorus sorption kinetics of soils of varying parent material and soil depth in south east Nigeria. The parent materials studied were: Coastal Plain Sand, Basalt, Shale and Sandstone and the depths were: 0 – 20cm, 20-40cm and 40-60cm. Soil samples were collected from the different parent material in three replicates a...

Ammonium Sorption Characteristics of Soils of Coastal Plain Sand in Owerri West Imo State

Osisi A. F*, Azu, Donatus E.O, Agim, L.C, Chukwu E. D

Information on the ammonium sorption capacity of soils is very crucial in the development of sound ammonium fertilization and management. This study was therefore carried out to determine the ammonium sorption characteristics of soils of coastal plain sand formation in Owerri West LGA of Imo State. Samples were collected from three locations (FUTO,...

Effect of Different pH Levels on Adsorption and Desorption of Pb in Contrasting Parent Materials of South Eastern Agro Climatic Zone of Nigeria

Nkwopara, U. N.*, Onwudike S,U., Ihem, E.E, Osisi A. F, Egboka, N.T

Lead adsorption and desorption at different pH levels in acid soils of diverse par- ent materials were evaluated. The soil samples were collected from soils under- lain by olivine basalt (Ikom), coastal plain sands (Ihiagwa) and false bedded sandstone (Ishiagu). The collected samples were air -dried, crushed, sieved with a 2 mm sieve and analyzed i...

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 ...
