Characterization of Organic Carbon Fractions in a Southwestern Nigerian Soil: an Acid Hydrolysis Approach

Shade Akinsete^*, O. F. Adebayoa, J. I. Uponib

Soil organic carbon characterization using acid hydrolysis is commonly performed at high temperatures but rarely at room temperature. This study used acid hydrolysis at 95 ºC and 25 ºC to quantify recalcitrant (non-hydrolyzable carbon, NHC) and labile C fractions of three depths in a planted fallow (Mucuna jaspedea) soil. Across depths, SOC fractions were: total SOC (11.83 – 21.57 g kg-1) > NHC 25...

Characterization, Classification and Land Suitability Evaluation of Soils Derived from Diverse Parent Materials in Central Cross River State of Nigeria for Arable Cropping

Nsor M.E.^*, Akamigbo, F.O.R.

The Physico-chemical characterization of soils derived from five parent materials in the humid tropics of South Southern Nigeria was studied. Soil properties such as texture, drainage, effective soil depth, nutrients status and reserves were employed for site suitability evaluation for arable cropping (cassava, maize and groundnut). Suitability classifications were arrived at by ‘matching’ the lan...

Profile Distribution of Selected Essential Micronutrients in Paddy Soils of Abia State, Southeastern Nigeria

AHUKAEMERE C.M.^*, Nkwopara, U. N., EKPENYONG O.S

Frequency of fertilizer application should be closely monitored to prevent excessive nutrient supply and environmental pollution. A field experiment was carried out in 2010 planting season at the Federal University of Agriculture, Abeokuta (FUNAAB) to determine the residual effect of organic and inorganic fertilizers on soil properties and maize yield. The treatments used were: compost (CP) derive...

Characterization, Classification and Management of Olokoro Soils Umuahia, Abia State Nigeria for Increased Dioscorea Dumetorum Yields.

Onyekwere I N^*, Nwosu P. O., Ezenwa M I S, Odofin A. J.

Trifoliate yam (Dioscorea dumetorum) is an important food security crop in Nigeria, it occupies a prominent position in the diets and farming systems in the South East agroecological zone especially in Abia State. Olokoro Soils, Umuahia South, Abia State, Nigeria grown to Trifoliate yam (Dioscorea dumetorum) were studied characterised and classified. Profile pits were dug and studied, using the ri...

Effect of Cassava Mill Effluent on Microbial Population and Composition in a Soil Planted to Maize (zea Mays L.)

Abhanzioya, M. I.^*, Ogboghodo, I. A, I.O. Osemwota

Experiment was carried out at Ambrose Alli University Teaching and Research Farm, Ekpoma, Edo State, to determine the effect of cassava mill effluent (CASME) on microbial population and composition in a soil planted to maize (Zea mays) in the screen-house and field. In the screen-house, cassava mill effluent (CASME) had five levels (0, 20, 40, 80 and 120 ml/kg soil) that were fitted into Completel...

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...
