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...

BIOACCUMULATION OF HEAVY METALS IN SOILS, Talinum triangulare and Celosia argentea LEAVES GROWN AROUND TEMBOGA RIVERBANK, BENIN CITY NIGERIA

EMOMU Adams*, OGBE Victor Etunim

Heavy metal levels in soils may result in heavy metal entry into the food chain, the study aimed at accessing concentration of heavy metals (Cd, Ni, Pb) in soils, Talinium triangulare and C. argentea leaf grown along Temboga Riverbank. Surface (0-15 cm) soil, T. triangulare and C. argentea leaf samples were collected randomly from Temboga Riverbank (RB), 60 meters from RB (60MRB) and 120 meters fr...

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...
