Soil Organic Carbon Fractions and Aggregation of a Tropical Alfisol as Affected by Plant Residues

ADESODUN Johnson Kayode*, Udom B. E., Abudu O. S., Adejuyigbe C. O.,, Enikuomehin O. A, Thannia B. M, Oke O. O., Olowokere F. A., Oyegoke, C.O,, Mbila M.

Incorporation of plant residues into soil plays a vital role in enhancing the quality of fragile tropical soils. This study evaluated the short-term effect of plant residues of different quality on organic carbon (OC) fractions, carbon management indices and stability of a sandy loam soil with low (< 2%) initial OC content. The residues are Banana clippings (BC), Chromolaena odorata (CO), Leucaena...

Organic Manuring on Fruits and Vegetable Production and Soil Properties in Landmark University, Omu - Aran, South - West Nigeria

Agbede O.O*, Fabiyi E.F., Adeleye, M.B.,, Nwafor S.I., Adekiya A.O.

Three experiments were established in the field within Landmark University Teaching and Research Farm during 2013 and 2014 cropping seasons (August – November each year). One experiment tested the response of tomatoes to Urea (at 40 kg/ha rate), NPK (40 kg/ha), Cowdung (5t/ha) and Poultry manure + NPK. The second trial tested the effect of varying levels of poultry manure + NPK. The second trial t...

Maximum Phosphate Adsorption Capacity as Influenced by Some Biochar Properties

Abdu N*, Solomon, R. I., Yusuf, A. A, Bello M.

The use of biochar as a low-cost adsorbent to remove nutrients from aqueous solutions is getting great attention lately due to its many environmental applica- tions and benefits. Although biochar has been widely used to remove phosphate from aqueous solutions, inconsistencies still exist with regards to biochar proper- ties responsible for the adsorption process. This research was therefore, carri...

Effect of Different Rates and Types of Fertilizers on Growth of Improved Coconut (cocos Nucifera)seedlings

AONDONA O.*, Ilori E.G., AWANLEMHEN B.E., UDOH M., OKONJO P.N

Comparative effects of different rates of inorganic and organic fertilizers on the performance of improved coconut palms (hybrid and dwarf cultivars) were evaluated using coconut seedlings planted in 15kg soils in polythene bags at screen house of NIFOR main station, Benin City, Edo State. The reference fertilizer used was NPK Mg 12:12:17:2 and was applied at rate 0, 28, 42, 56 and 72g/pot (this w...

Properties and Sustainable Management of the Inland Wetland Soils for Efficient Rice Production in Southern Guinea Savanna Zone of Nigeria

Ogbu O. J,*, Usman, J., Orohu T. O, Onah J.E.

A pedological study was carried out on some inland wetland soils of Obukiyo, Oju Local Government Area of Benue State, Nigeria to identify their properties and suggest sustainable management practices for the soils. The grid method of soil survey was employed in the field to investigate the morphological and physicochemical properties of the soils. Four soil units were identified on the field base...

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, C.L.A

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.,*, Girei, A. H., Mahmud A.T, Onokebhagbe, V. O., Yusif, S.A.,, Santuraki, H.A., Nzamouhe M

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...
