Olowokere F. A.^*, ADESODUN Johnson Kayode, BABALOLA O. A., AKINTOKUN Pius Oluwagbemiga, ADEYEYE A. A

A study of gully erosion effects on soil properties in some soils of Edo State. Nigeria was investigated under natural conditions in five (5) gully sites from four Local Government Areas (Ekehuan Road in Oredo L.G.A. Ambrose Alli University, Ekpoma in Esan West L.G.A., University of Benin Campus in Ovia North East L.G.A., Agbo Motor Park Road and Temboga in Ikpoba Okha L.G.A.). Control and gully s...

The Fertility and Management Imperatives of the Degraded Upland Soils of Ebonyi State, Southeast Nigeria

Ogbodo E. N^*

Soil fertility evaluation of some continuously cultivated Upland Soils in Ebonyi State, Southeast Nigeria, was assessed to determine their levels of degradation, as a basis for soil health management to increase their productivity. Results showed that the soils are generally fine loam, very strongly acidic (average pH 4.9), and soils with very low base saturation of below 60 %. They are low in org...

Research Note Toxicity of Soil in Agunji Marble Mining Area of Kwara State, Nigeria

Olatunji K. J.^*

Soils in areas of mining operation are used in cultivating crops in Kwara State. This makes it imperative to monitor the concentrations of toxic heavy metals in the soil. The concentrations of Mn, Fe, Cu, and Zn at 10m intervals from the centre of marble quarry were determined up to 110m distance. Values of extractable Mn varied from 1.73 to 10.8, Fe 6.0 to 19.8, Cu 0.55 to 2.8 and Zn from 0.03 to...

Effects of Abattoir Effluent on the Yield and Yield Components of Maize (zea Mays) in Forest - Savanna Transitional Zone of Edo State, Nigeria

Abhanzioya, M. I.^*

Field experiment was carried out in the Forest–savanna Transition Zone of Ambrose Alli University, Ekpoma, Edo State, Nigeria to assess the effect of abattoir effluent on the yield and yield components of maize (Zea mays). The soil used for the experiment was analyzed for both its physical and chemical properties while the effluent used was also analyzed for its chemical properties before the expe...

Assessment of Degradation Status of Soil in Selected Areas of Benue State Southern Guinea Savanna of Nigeria

Adaikwu A.O^*, M.E. Obi, Ali A.

The assessment of degradation status of soils in selected areas of Benue state was carried out in 2009. The physical and chemical properties of these soils were evaluated in the laboratory and the results obtained were compared with the standard indicators and criteria for land degradation assessment according to (FAO 1979). The results showed that most of the cultivated parts of the study areas w...

Influence of Slope and Depth on Soil Chemical Properties in an Oil Palm Plantation

O. O. Olubanjo^*, MAIDOH F.U.

A study was carried out in a 28-year old Oil palm (Elaeis guineesis) plantation established on a gently sloping terrain in NIFOR Benin, Nigeria to determine the geo-spatial distribution of soil chemical properties as influenced by slope position and depth and also the assess the relationship between soil chemical properties with slope and depth. A line transect was delineated along the slope of th...

Morphological, Physicochemicaland Mineralogical Properties of Soils Developed from Basalt Atikom, Cross River State, Nigeria

I. E. Esu^*, U. Uko, E. E. Aki

Soils developed from basalt were studied along with a top sequence of a deeply excavated basaltic quarry site at Ikom, Cross River State, Nigeria. The soils were very deep and occupy gently sloping plains of 0 – 8% gradients. Each pedon examined, had four distinct layers, the Ap, BA, Bt and Crtg horizons. The Ap horizons have dark reddish grey (5YR 4/2) to dark reddish-brown (5YR 3/4) colours whil...

Responses of Melon (collocynthis Citrullus) and Soil Chemical Properties to Different N - Sources in Ado – Ekiti, Southwestern Nigeria

B. Osundare^*

A two – year field experiment was conducted at the Teaching and Research Farm of the University of Ado – Ekiti, Ekiti State, Nigeria, during 2008 and 2009 cropping seasons to determine the effects of different N – sources on soil nutrient status and yield of melon (Collocynthis citrullus). The experiment was laid out in a Randomized Complete Block Design with three replicates. The different source...

Effect of Gully Erosion on Soil Properties in Some Soils of Edo State, Nigeria

OLEGHE E.E^*, CHOKOR J.U.

The research was carried out to investigate the effects of mycorrhizal inoculation and crop rotation on the growth and biomass production of maize. Maize as a staple food is grown in almost all part of the world but the threat to its sustainable production is declining soil nutrients. It had been reported that continuous use of chemical fertilizer has negative effects on ecological system and can ...

Evaluation of Mycorrhiza and Pigeon Pea Leaves Compost on the Growth, Yield and Nutrient Uptake of Maize in Degraded Ultisol

Dania S. O.^*, Fagbola O.

Soil nutrient and organic matter replenishment cannot be attained by the use of inorganic fertilizer alone hence, the advocation for the use of integrated fertility management method to improve soil fertility for continuous crop production. Two-season pot experiment was conducted at the Teaching and Research Farm, Ambrose Alli University, Ekpoma, Edo State to assess pigeon pea leaves compost and m...
