Olufemi Adewale Osinuga*, Janet Oluwafunmilayo Sulaimon, Anuoluwapo Ayomide Ojo, Lateefat Abisola Taoreed, Victory Tega Kagbare, Ezekiel Abiodun Samuel, Bolarinwa Ayoola Senjobi

Iron (Fe) and aluminium (Al) forms are important properties for understanding soil-forming processes and serve as helpful markers in identifying the horizon where secondary oxides accumulate. This study evaluated the physical, chemical, and extractable forms of Fe and Al in Eriti wetlands, Ogun State, Nigeria. The wetlands were mapped, and three soil pedons were dug and sampled across genetic hori...

Variations in Soil Properties as Influenced by Land Use and Soil Depth in a Derived Savannah Ecology of Southwestern Nigeria.

Denton O.*, Ogunkunle A. O., Fademi I.

Soil physical and chemical properties are strongly influenced by soil management systems and changes in land use. The study was carried out in Iseyin LGA of Oyo state which is a derived savannah zone under four different land use types’ arable, grazing, fallow and tree crops. A total of twenty four soil samples were collected at two depths i.e. 0-15cm and 15-30cm, from the study area using the clu...

Use of a GIS-Based AHP and Parametric Square Root Method for Land Suitability Assessment of Groundnut (Arachis hypogea L.) on Gurumpawo Toposequence

Solomon Adamu Gisilanbe*, Abdulrashid Shobayo Babatunde, Sulaiman Yau Lawan, Muhammad ISMAIL, Lemuel Musa Maniyunda, Jamila Aliyu, Hussain Abba Ahmad, Ummi Salma ZUBAIRU

This study assessed the cultivation potential of groundnut (Arachis hypogaea L.) along Gurumpawo toposequence, Ganye, Adamawa State, using the parametric square root method (SRM) and the Analytic Hierarchy Process (AHP). Sustainable groundnut production in the area is threatened by declining soil fertility and topographic variability, while site-specific suitability information for precision land ...

Assessment of Soil degradation in response to Land use change in the Federal University of Agriculture Abeokuta, Nigeria.

Adebayo Ibrahim Ajibola*, Tobore Anthony Olamiji, Oyeyemi Omotola

Soil degradation is a worldwide concern that poses significant threats to the physical, chemical and biological conditions of soil leading to food insecurity and instability of ecosystems. Therefore, assessing and monitoring soil degradation especially in the teeming developing population countries such as Nigeria calls for urgent attention. Hence, in this study, randomized method was used in the ...

HEAVY METAL TOLERANCE AND HYDROCARBON-DEGRADING POTENTIAL OF INDIGENOUS SOIL BACTERIA ISOLATED FROM OIL SPILL SITES IN BERE COMMUNITY RIVERS STATE, NIGERIA

Ikwuakonam Okoro*, Laura N. Chigozie-Nwogu

Contamination from oil spills in Nigeria's Niger Delta has led to widespread co-contamination of soils with petroleum hydrocarbons and heavy metals, creating significant environmental and ecological problems. This research aimed to test the hydrocarbon-degrading capacity and heavy metal tolerance of indigenous soil heterotrophic bacteria isolated from oil-polluted sites in the Bere community in th...

Residual Effects of Sawdust and Poultry Manure Biochars on Soil Chemical Properties and Vegetative Growth of Maize in Degraded Soils of Southwestern Nigeria

Ehigiator Nosakhare Gideon*, Oyinlola Olamide

Soil fertility decline remains a major limitation to maize productivity in sub-Saharan Africa, where restricted access to fertilizers constrains efforts to close yield gaps. Sustainable soil management strategies that enhance residual nutrient availability are therefore critical for maintaining crop performance under low-input conditions. This study assessed the residual effects of sawdust biochar...

Characterization, Classification and Suitability Assessment of Nigeria Soils: A Review

Olasoji Hannah Olufemi*, Ojetade, J. O., Muda, S. A., Amusan, A. A

Effective soil management and conservation may be impossible without accurate soil characterization, classification and interpretation in relation to particular crop requirements. Proper management of soils is therefore indispensable because of its linkage to environmental protection, hunger eradication/food security, economic growth and poverty reduction among others. Research efforts on soil cha...

Effect of exchangeable calcium and magnesium as essential for soil chemistry and plant nutrition in organic manures- treated soils for sustainable agriculture.

HABEEBAH SAKA*, Azeez Jamiu Oladipupo, Alabi Khadijat Oyebisi

Calcium and magnesium are important secondary nutrients that contribute to soil fertility, nutrient balance, and sustainable crop production. This study evaluated the mineralization of soil exchangeable Ca2+ and Mg2+. The study was conducted at the Teaching and Research Farm of the Federal University of Agriculture, Abeokuta. The experiment was a randomized complete block design with three replica...
