Characterization, Classification and Agricultural Potential of Some Selected Soils of Kwara State, Nigeria

OLANIYAN J. O.*

The major soils of Kwara State were identified using the FDALR- produced soil map of Nigeria. These soils were mapped. Soil samples were taken from pedogenic horizons and analysed in the laboratory for further characterization and classification. The soils developed on basement complex rocks are gravely while those developed on sandstone are more sandy and free of coarse fragments. The soils are g...

Characterization, Classification and Suitability Evaluation of Soils on Three Geological Formations in Nsukka Area of Enugu State for Pepper Production

Umeugokwe C. P*, Ajoagu, G.M, Asadu Charles Livinus

This study aimed to characterize, classify, and evaluate the soils on three geological formations in Nsukka, Eastern Nigeria for pepper production. The geological formations included Upper Coal Measure (UCM), False Bedded Sandstone (FBS), and Nkporo Shale (NS). Three pedons were excavated to represent each of these geological formations. Soil properties were determined using appropriate methods. T...

Review of Various Studies of Tillage Practices on Some Soil Physical and Biological Properties

Nabayi, A.,*, Abubakar Halilu Girei, Mahmud A. T., Victor Onokebhagbe, Yusif, S.A.,, Santuraki, H.A., Maximillien Nzamouhe

The objective of this paper was to review the various studies of tillage practices effects on some selected soil physical and biological properties from 2000 to 2021 and summarise the findings. The findings of the review indicated that generally, No-tillage (NT) systems have greater benefits than the conventional tillage systems under various soil, environmental, and management conditions. These b...

Evaluation of Soil Development on an Erosional Landscape of the Nigerian Guinea Savanna

Ayodele Owonubi*

Soil landscape relationship is an essential tool for evaluating soil development. This study was carried out to evaluate soil development on an erosional land- scape of the Nigerian guinea savanna. Field studies were carried out by augering to a depth of 105 cm and by studying soil profiles along gully walls and stream channels in selected locations. Profile description and soil sampling were done...

Effects of Poultry Litter and the Residues of Maggot’s Production on Chemical Fertility of a Lixisol and Maize (zea Mays L.) Yield in Western of Burkina Faso

Kalifa Coulibaly*, Fernand Sankara, Salimata Pousga, Philippe J. Nacoulma, Marc B. Somé, Hassan B. Nacro

Organic substrates have shown their importance in the sustainable management of soil fertility and crops production. A study was conducted during 2 years (2016 and 2017) at western of Burkina Faso to evaluate the effects of poultry litter (PL) and the residues of maggots’ production (RMP) on soil chemical fertility and maize yield. The experimental design was a completely randomized block design w...

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., Peter I. Ezeaku, 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...
