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, Ihiagwa and Umuokanne), at three depths (0-15, 15...

Cowpea (vigna Unguiculata [l] Walp) Response to the Application of Npk Fertilizer in a Ferric Luvisol

Obianuju Chiamaka Emmanuel*, Olayiwola Akin Akintola, Dorcas Tinuka Ezekiel-Adewoyin, Francis Marthy Tetteh

This study evaluated the response of cowpea to nitrogen (N), phosphorus (P), and potassium (K) fertilizer applications in a ferric luvisol of the Guinea Savanna zone of Ghana, West Africa. The treatments were arranged in a randomized complete block design with 4 replications and carried out in two seasons. Performance of Omondaw cowpea variety was evaluated at different combinations of Nitrogen (0...

Growth and Yield of Okra and Tomato as Affected by Pig Dung and Other Manures Issue for Economic Consideration in Benue State

ABEL OLATUNJI ODEYEMI*, V. U. Oboh

Pot experiments were conducted to compare the effects of pig dung and other sources of manure on the production of okra (Abelmoschus esculentum) and Tomato (Lycopersicon esculentum mill) at University of Agriculture, Makurdi. A survey was also conducted in Makurdi metropolis to determine the comparative availability and cost of pig dung and other manures. Three levels of organic manures were used,...

Phosphorus Sorption by Some Hydromorphic Soils of Southern Nigeria

Aghimien A.E.*, Ilori E.G., Ehigiator J.O.

A laboratory experiment was conducted on fifty-eight (58) surface soils from five different soil parent materials in Southern Nigeria. Samples were equilibrated with different P concentrations ranging from 0 - 150 mg/L prior to evaluation sorption potentials. The Phosphorus Sorption Index (PSI) of the soils ranged from 4.80 to 64.90. The PSI values correlated significantly with some of the soil pa...

Assessment of Degradation in Soils of Transplanted Shea Tree (vitellaria Paradoxa Gartn C. F.)under Two Land Use Types at Bida, Niger State

OSAYANDE P.E.*, P.O. Oviasogie, EKEBAFE M.O, MAIDOH F.U.

Land use affects the fertility and management of soils. The influence of contrary land use types imposed on a Shea field was studied at NIFOR Substation, Bida, Niger state. The field, a sparse grass fallow measuring a 100m X 100m was demarcated into two equal halves. A portion of it was cleared and planted to melon while the sparse grass fallow was retained in the other portion. Composite surface ...

Soil Erosion Risk Assessment: a Case Study of the Jos Plateau, Nigeria

Ayodele Owonubi*

Soil erosion is a treat to global food security. The objective of this study was to evaluate factors influencing erosion on the arable lands of the Jos Plateau, and to estimate the extent of soil erosion in the area. Universal Soil Loss Equation (USLE) model was used to evaluate soil erosion processes in the study area. This was facilitated with the aid of Geographic Information System Both for In...

Spatio - Temporal Assessment of Soil Microbial Biomass Carbon Around Industrial Area of Kano Metropolis, Nigeria

Mohammed M. A.*

The soil microbial biomass carbon (MBC) acts as the transformation agent of the organic matter in soil as such the microbial biomass carbon is both a source and sink of some soil nutrients C, N, P, and S contained in the organic matter. The study is aimed at assessing the seasonal variation of soil microbial biomass carbon in contaminated soil. Ten soil samples were collected in contaminated and c...

Geospatial Predictive Model for Estimating Soil Thermal Conductivity and Diffusivity of Owaza Gas Flaring Site , Southeastern Nigeria

Nwagbara, M.O*, Irondi, A.O., Uzoma, K.C, Adesemuyi E.A

In this study, predictive model for estimating the soil thermal conductivity and diffusivity from fourteen different sample points around a horizontal gas flaring site was employed in two depths (0 – 15 cm and 15 – 30 cm). Seven of these points were within the gas flare bond wall. In contrast, other points were located outside the bond wall at varying distances in the direction of the flaring. Soi...
