Mineralogical Investigation of Some Imperfectly and Poorly Drained Soils of the Nigerian Northern Guinea Savanna Agroecology

Abdulrashid Shobayo Babatunde*, Sulaiman Yau Lawan, Aliyu, J.,

This study aimed to investigate the mineralogy of soils with impaired drainage formed within the northern guinea savanna of Nigeria. Soil survey procedure was carried out to identify the two soil individuals (polypedon) namely: imperfectly drained soil (IDS) and poorly drained soil (PDS) that occupied 6,407.68ha (90.96%) and 636.82 ha(9.04%) respectively. In each soil individual, a repre- sentativ...

Variability of Some Properties of the Nun River Plain Soils in Bayelsa State, Nigeria

Achimota A. Dickson*, Tate, Joseph O., Ogboin, P. T, Payebo, O. C, Agbai, W. P.

Whereas studies on spatial variability of soil properties on toposequences are well documented, information on the variability of characteristics of floodplain soils is lacking. This study, therefore, evaluates the status and variability of the soil properties in three physiographic units in two locations on the Nun River floodplain. Silt-sized particles dominated soil texture and soil texture var...

Hydro - Geomorphic Study on Selected Soil Properties, Classification and Management Considerations of Soils on Alluvial Landforms in Southeastern Nigeria

Obiageli Patience Umeugochukwu*, Akamigbo, F.O.R., Chude, V.O, Eze P.N

The soils were characterized with regards to their macro morphology, physicochemical properties and heavy metal contents. This is to infer their pedogenesis and propose agrotechnology transfers as well as management considerations necessary for sustainable cultivation. Reconnaissance survey was used for initial soil identification. Two categories of the flood plain soils were identified viz. the l...

Fertility Baseline Study of Major Cocoa Growing Soils of Nigeriaand Implication for Cocoa Production in Nigeria

AJIBOYE G. A.*, Jaiyeoba, J. O., Olaiya, A. O., Hammed L. A.

"Field and laboratory studies were conducted to evaluate the fertility status of the soils of three major cocoa-producing States in Nigeria. A Survey of the selected Local Government Areas was carried out and soil samples were collected at 0-30 and 31-60 cm depths. The Physico-chemical properties of the soils were assessed in relation to cocoa nutritional requirements using standard methods while ...

Effects of Organo-Mineral Fertilizer and Cocoa Pod Husk Ash on the Soil, Leaf Chemical Composition and Growth of Coffee

Adejobi K.B*, Famaye, A. O., Oloyede A.A., Oyedokun A.V, Adeosun S.A, Adeniyi D.O.

A nursery experiment was carried out in Ibadan (rain forest zone), Southwest Nigeria to study relative effect(s) of combined use of organo-mineral fertilizer (OMF) and cocoa pod husk ash (CPHA) on soil chemical properties, nutrient status and growth of coffee seedlings (Coffea arabica L.). Eight treatments: 5t/ha CPHA, 20 t /ha OMF, 20 t/ha OMF + 5t/ha CPHA, 15 t/ha OMF + 5 t/ha CPHA, 10t /ha OMF ...

Impact of Littered Sachet Water Plastics on Soil Infiltration Capacity in Agricultural Lands of Gwagwalada, Nigeria

Hadiza Hadiza Abubakar Ahmad*

The ubiquitous consumption and indiscriminate disposal of sachet water plastics across Nigeria have exacerbated environmental degradation, particularly affecting soil health in agricultural landscapes. Recent studies reveal that polyethylene-based microplastics, which dominate sachet water waste, can significantly alter soil structure, reduce porosity, and limit microbial diversity, thereby degrad...

Instrumentation in Soil Science: An advanced overview

Suleiman Usman*, Jayeoba Olumuyiwa James, Amana S. M.

This paper provides an overview of what soil science instruments entail in the global academic environment. This paper focused on developments in advanced soil science equipment with a specific compilation of forty (40) different instruments and their brief application. These sets of instruments are found to be applicable in soil science based on (a) optical methods, which focus on the measurement...

Evaluation of Aratibiotech Organomineral Fertilizer Effect on Lowland Rice Production

Bakare S.O*, Aliyu A, Ekaette J.E, Ukwungwu, M.N

A Randomized Complete Block Design experiment with three replicates was carried out at the lowland experimental site of the National Cereals Research Institute, Badeggi in the 2011 and 2012 wet seasons. National Cereals Research Institute, Badeggi is located at Lat. 09o 45’N; Long. 06o 7’E Organomineral fertilizer was applied at the rate of 2, 3, and 4t/ha while no fertilizer application, as well ...

Physical and Chemical Properties of Soils in Kogi State, Guinea Savanna of Nigeria

S.O. Amhakhian*, I.O. Osemwota

This experiment was conducted in Kogi State. Twenty composite surface soil samples (0.15cm depth) drawn from two distinct geological formations (Cretaceous sediments and Basement complex) were used for the study. These soils were collected from different sites with varying cropping history. Particle size analysis of the soils used indicated a high proportion of sand, the texture of the soils range...

Soil Microbial Activity Under Complementary Applications of Organic and Inorganic Amendments

Sangotoye S. E.*, Atere C. T., Taiwo, L. B, Olayinka A.

The research described and quantified soil consistency as cumulative consistency value (CCV) at two moisture levels for different horizons of soil profiles located on sedimentary and basement complex parent materials. It was found that the CCVs of soils formed on sedimentary deposits were between 18 and 28 while the CCVs for the soils formed on the basement complex were between 0 and 27. No signif...
