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...

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...

Profile Distribution of Forms of Iron and Aluminium Oxides in Wetland Soils Formed Over Recent Alluvium

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...
