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, M.O. Ekebafe, 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, Emmanuel Adeboye

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...

Influence of Lime and Gypsum Application on Soil Properties and Tuber Initiation of Cassava(manihot Esculenta Crantz.) in a Degraded Ultisols in Agbani, Enugu Southeastern Nigeria

EZE J.C.*, Anikwe M. A. N, IBUDIALO A.N

The experiment was carried out to examine the influence of Lime and Gypsum on soil physicochemical properties in a degraded ultisol during 2013 and 2014 Rainy season in Agbani, Enugu Southeastern Nigeria (60 29’N and 70 54’E). A Randomized Complete Block Design (RCBD) using Lime and Gypsum as treatments at the rate of Lime 5000 kgha-1, Gypsum 2500 kgha-1, Lime 5000 kgha-1 + Gypsum 2500 kgha-1 and ...

Fertility Evaluation of Some Soils in Adamawa State, Nigeria

Hassan M.*, Saddiq A. M., A. Ibrahim

Surface (0-25) and sub-surface (25-80) soil samples were collected from Hong, in Hong Local Government and Chouchi plains, Yola South Local Government with the aim of evaluating their fertility status. The soils were evaluated both in the field and laboratory. Results of the analyses showed that sandy loam soils dominated the upper layers, sandy clay loam to clay loam in the lower horizons in Hong...

Effect of Npk and Poultry Manure on Cowpea and Soil Nutrient Composition

ABEL OLATUNJI ODEYEMI*, S.A. Ayuba, B.C. Anjembe, OJENIYI STEPHEN OLUSOLA

Field experiment was conducted at University of Agriculture, Makurdi in the Southern Guinea Savanna ecology of Nigeria to test effect of NPK fertilizer and Poultry manure on performance of cowpea and soil nutrient composition. The study conducted in 2008 and 2009 had a control, NPK 20 – 10 – 10 (48 kgha-1) and poultry manure (PM) with or without NPK fertilizer. The test soil was deficient in N and...

Geospatial Distribution of Soil Reaction in Central Southeastern Nigeria

Onyechere A U*, Onweremadu E. U, Aririguzo, B. N, AHUKAEMERE C.M.

The study applied Geographic Information System (GIS) in the Study of Soil Acidity Distribution in Soils of Central Southeastern Nigeria from six different parent materials, namely Imo Clay Shale, Ajali Sandstone, Asu River group, Afikpo Sandstone, Ogwashi-Asaba formation and Bende Ameki formation. Free soil survey method was used to site the eighteen profile pits investigated. The pits were geo-r...

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 sampling technique was employed in locating 3 distinct to...

Soil Mapping and in - Situ Soil Description of Selected Land Area of Funtua, Nigeria

Abdulrashid Shobayo Babatunde*, Sulaiman Yau Lawan, Tarfa, B.D.

The study was done to delineate soil mapping units and produce the soil map of a selected 10 000 ha land. Landsat imagery of the study area was acquired and used for land cover and land use identification. Digital Elevation Models (DEM) of 10 m resolution was also obtained to produce landforms and contour maps. A 10 000 ha land was delineated from the landform map and divided with grids at 400 m i...
