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

Adaikwu A.O^*, Obi Martins Eze, A. Ali

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...

Effect of Composted Empty Oil Palm Fruit Bunches on the Growth and Yield of Amaranthus and Soil Physicochemical Properties

P.O. Oviasogie^*, Oko-Oboh E., E.I. Eguagie

The effect of composted empty oil palm fruit bunches (EFB) on the growth and yield components of Amaranthus and soil physicochemical properties was evaluated at the Nigerian Institute for Oil Palm Research (NIFOR) main station. The composted EFB was applied at four different rates of 0, 10, 20, and 30 tons/ha. The experiment was replicated four times and arranged in a randomized complete block des...

Enhancing Soil Quality and Sustainable Agriculture: A Review of Black Plum (Syzygium cumini) for Soil Amendment and Productivity

AKANBI Olorunfemi Sunday Ojo^*, Isaac Kayode Oyewusi, Adegbala, A. A, Nduka B. A., Ipinmoroti, R.R.,

Jamun (Syzygium cumini), widely known as black plum, is a highly adaptable fruit-bearing tree with exceptional nutritional, medicinal, and ecological advantages. Despite its resilience in tropical and semi-arid regions, especially in areas like Northern Nigeria, its integration into formal agricultural systems remains minimal. This review synthesizes current findings on the plant’s agronomic trait...

Description and Characterization of Soils Supporting Vitellaria Paradoxa (shea Tree ) in Different Geo - Ecology in Nigeria

P.O. Oviasogie^*, Oko-Oboh E., D.O. Oseghe

Characterization of soils supporting shea tree in different Geo-ecology was carried out. This was done using the International Plant Genetic Resources Institute (IPGRI) descriptors for environment and site characterization adapted from FAO. The result indicates that the climate (Rainfall and Temperature) of the different geo-ecology has slight variation, but wide variations exist in the different ...

Effects of Mycorrhizal Inoculation and Crop Rotation on Maize Growth and Biomass Production

AMUSAT M.A^*, OSONUBI O, OYETUNJI O.J

In a pot experiment, this study examined the impact of selected organic amendments on coastal plain and acid sulphate soils. Maize was used as a test crop. The treatments were as follows: cattle manure (cm), sheep manure (sm), mushroom production waste (mpw), water hyacinth (Eichhornia crassipes) biomass (whb) and urea. A completely randomized design with four replicates was used. Routine laborato...
