Characterization and Fertility Status of Wetland Soils in Abia State Agro-Ecological Zone of Southeastern Nigeria.

AHUKAEMERE C.M.*, ESHETT E.T, AHIWE C.

The realization of the potentials of paddy soils necessitates taking the inventory of their micronutrients status. The available micronutrients status of soils of two varying paddy lands (upland and lowland) were studied. A random soil survey technique was used in field sampling. Four representative soil profiles, two in each paddy soil type were dug. Soil samples were collected from the profiles ...

Combined Application of Ureaand Sawdust Ash in Okra Production Effects on Yield and Nutrients Availability

Temitope Okusami A*

Trials were conducted at Emmanuel Alayande College of Education Teaching and Research Farm Lanlate, southwest Nigeria in 2012 and 2013 to investigate the effects of combined applications of sawdust ash (SDA)and urea (U) as fertilizer in okra production. There were five treatments and control, replicated three times in randomised complete block design. Treatments were a control, urea at 240 kg/ ha,...

Contaminant Limit (c/p Index) of Heavy Metals in Spent Oil Contaminated Soil Bioremediated with Legume Plants and Organic Nutrient

Udom B. E.*, Ano, A. O., Chukwu L. I.

Three legume plants (Gliricidia sepium, Leucaena luecocephala and Calapogonium caerulean) alone or in combination with 0.5% (w/w) poultry manure were tested for their ability to reduce the heavy metals and toxicity criteria of a sandy soil contaminated with 5% (w/w), (equivalent of 50,000 mg/kg) spent lubricating oil, each for two years. The oil and poultry manure led to buildup of Ni, Pb, Zn and ...

An Assessment of Land Use/cover Using Conventional and Satellite Data in Tomas Irrigtion Scheme, Kano, North - Western Nigeria.

Sulaiman Yau Lawan*, B. A. Raji, MALGWI W.B., Uyovbisere E, Manasseh E.A.

Soil is a life supporting system upon which human beings have been dependent from the dawn of civilization. Hence comprehensive information on soil resources, its potentials, limitations and capabilities are required for a variety of purpose, which includes sustainable agriculture, reclamation of degraded lands among others. Data from SPOT 5 (2005), a satellite image and ERDAS, a geographic Inform...

Potassium Distribution in the Sand, Silt and Clay Fraction of Soils Developed Over Talc in Odo-Ogbe, Kogi State, Nigeria

AJIBOYE G. A.*, Ogunwale J. A., Aduloju M. O.

Potassium (K) status of soils formed over talc at in a Southern Guinea Savanna Zone of Nigeria was assessed by the exchangeable, acid extractable, residual K and total K values in the sand, silt and clay fractions of the soils. Soil samples collected from genetic horizons of profile pits dug in five mapping units were fractioned into the three particle sizes of sand, silt and clay and exchangeable...

The Impact of Various Fertilizer Inputs on the Growth, Nodulation and Yield of Soybean (glycine Max )cultivated on an Alfisol in Minna, Southern Guinea Savanna of Nigeria

Uzoma, A.O.*, Okoh J, Bala A., Adeboye M.K.A, Osunde A.O.

Growth and yield response of soybean variety TGX 1448-2E to various fertilizer inputs was assessed in a field experiment at the Teaching and Research Farm of the Federal University of Technology Minna during the 2010 rainy season. Treatments consist of five fertilizer combinations as follows: Zero fertilizer application at 0 kg Pha-1, Rock phosphate at 30kg P ha-1, single super phosphate at 30kg P...

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

S. J. 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...
