Soil Organic Carbon Stocking Ability of Some Soils Under Oil Palm (elaeis Guineensis Jacq.) and Rubber (hevea Brasiliensis Muell Arg.) Plantations in Edo State, Nigeria

Emmanuel O. Ufinomue*, Ehis- Iyoha E.

This study evaluated soil organic carbon stock and its relationship with some soil microbial, physical and chemical properties. The soils were Alagba, Orlu, Ahiara and Kulfo series located in two (2) locations within Edo State namely, Nigeria Institute for Oil Palm Research (NIFOR), Benin City, (latitude 06.33’ to 06.47’N, longitude 05.37’E to 05.46’E) and Rubber Research Institute of Nigeria (RRI...

Impact of Open Cast Mine Land Use on Soil Physical Properties in Enyigba, Southeastern Nigeraand the Implication for Sustainable Land Use Management

Okolo, C.C.*, Akamigbo, F.O.R., , Ezeaku, P.I., Nwite, J.N, Nwite, J.C, Ezeudo, V. C, Ene, J., Ukaegbu, E. P, Udegbunam, O.N., Eze, N. C

The study examined the extent of soil physical properties deterioration due to mining activities in Enyiba Ebonyi State, Southeastern Nigeria. In the study, two factors were considered: factor A - Soil depths (surface soil: 0-15 cm and subsurface soil: 15-30 cm) and factor B - Distances from mine pits (100 m, 200 m, 300 m, 400 m and 500 m away from mine pit). Four mining sites (Mbaraeke Enyigba, M...

Yield Response of Maize (zea Mays L.) and Soil Nutrients to Time and Methods of Npk Application

B. Osundare*

A study was carried out at the Teaching and Research Farm of the University of Ado-Ekiti, Nigeria, during early 2008 and 2009 cropping seasons to determine the effects of time and methods of NPK fertilizer application on yield of maize (Zea mays L.) and soil nutrients. The design was split – plot, laid out in a Randomized Complete Block, with three replicates. Time of NPK fertilizer application co...

Short - Term Effect of Soil Tillage and Npk Fertilization Rates on Soil Carbon Sequestration and Yield of Colocasia Esculenta Schott in Two Micro - Environments in Se, Nigeria

Anikwe M. A. N*, Ikengannyia E. E

Quantification of soil organic carbon cycling as impacted by soil and crop man- agement practices is required for C storage and soil quality improvement investi- gations. This study assessed the short-term effect of conventional tillage (CT) and No-Tillage (NT) practices on SOC sequestration and yield of cocoyam (Colocasia esculenta). The experiment was conducted simultaneously at two lo- cations ...

Effect of Npk, Mg, Biochar. Compost and Oil-Palm Waste in Prenursery Oil-Palm Seedling Production

AONDONA O.*, EZEKIEL AKINKUNMI AKINRINDE

The effectiveness of organic fertilizer materials (decomposed Empty Fruit Bunch, EFB: Sunflower Compost, SFC; Palm-Oil Mill-Effluent, POME, Palm Kernel Cake, PKC and Biochar) for the production of oil-palm seedlings at the pre-nursery (four-month stage) were evaluated, using NPK Mg 12:12:17:2 as reference. In an initial pot experiment (employing 2 kg soil samples per 2.5 x 25 cm2 polythene bag), r...

Evaluation of Lower Niger River Floodplain Soils of Bayelsa State, Southern Nigeria for Their Agricultural Capabilities

Achimota A. Dickson*, FunsoR. Kutu, Joseph Aruleba

Capabilities and fertility constraints to crop production of the Lower Niger River floodplain soils were assessed using Land Capability Classification (LCC), Land capability Index (LCI), and the Fertility Capability Classification (FCC) systems. The LCC grouped the nine soil mapping units (SMUs) into class II, suited for a wide range of arable crops while LCI grouped ELM1 into class I, ODN1 and TF...

Effect of Organic Soil Amendments on Soil Chemical Properties in Sudan Savannah of Nigeria

Aliyu Abdulkadir*, Mansur U. Dawaki, Mahmud Sani

Composite soil samples were collected from irrigated maize fields, to study the effect of Bio char and Compost on post harvest soil chemical properties in the Sudan Savannah of Nigeria. Laid on a completely randomized block design, the treatments used in the experiment were 5tha-1 Bio char, Compost, and Control. Pre-amendments application and post maize harvest soil characteristics obtained from l...

Wetlands are one of the most productive habitats globally, with socio-cultural and economic relevance. They are, however, at risk of heavy metal contamination. This study investigated metals distribution and potential ecological risk in wetland soils at the Federal University of Agriculture in Abeokuta, Nigeria. Soil samples were collected in March 2021 and analyzed using standard methods. Metal c...

Nkwopara, U. N.*, Onwudike S,U., Ihem, E.E, Osisi A. F, Egboka, N.T

Lead adsorption and desorption at different pH levels in acid soils of diverse par- ent materials were evaluated. The soil samples were collected from soils under- lain by olivine basalt (Ikom), coastal plain sands (Ihiagwa) and false bedded sandstone (Ishiagu). The collected samples were air -dried, crushed, sieved with a 2 mm sieve and analyzed in the laboratory. The adsorption of lead (Pb) incr...
