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...

Pedogenesis, Weathering Intensity, and Soil Development in the Northern Guinea Savanna of Zagga District, Northwestern Nigeria

Ibrahim Babagana Buji^*, Murtala Bawa Sharu, Noma, S. S, Abubakar G. A, Eniolorunda N. B, Talha I. Z, Hayatu N. G

Understanding pedogenetic processes and weathering dynamics is fundamental to characterizing soil development and guiding sustainable land management in tropical savannas. This study evaluated the pedogenic processes, weathering status, and stage of soil development in Zagga District. Field investigations of eight representative soil profiles were conducted and their morphological description, fol...

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

Gisilanbe Solomon Adamu^*, 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 ...

Soil Physical and Chemical Spatial Patterns under Land Use Intensification in a Nigerian Protected Area

Adesina Abudlkabir Wahab^*, Kabir Kayode Adebayo, Toyeeb Abayomi Abioye, Yusuf Folorunso Abdulkareem

Population growth, food demand, and low farm income drive landuse intensification and encroachment into protected areas. Landuse intensification within protected landscapes alters soil physical and chemical properties with implications for ecosystem stability. This study quantified soil variability across four land-use types (LUTs): long-term reserved forest (>10 years; RAG), recently reclaimed re...

Comparative evaluation of chitosan-based biopolymer and conventional phosphorus extractants on phosphorus availability, soil pH dynamics, and maize agronomic performance in amended soils

Ganiyu Olawale Bankole^*, Adeoba Courage Aghorunse, Festus Adelana, Racheal Ayo Buzugbe, Sheriff Adewuyi, Jamiu Oladipupo Azeez

Phosphorus (P) availability in tropical soils is commonly restricted by strong fixation processes, mainly through adsorption onto iron and aluminum oxides and precipitation with calcium compounds, which significantly reduce its mobility and plant utilization. This study evaluated the effectiveness of chitosan-based biosorbents (nZvFe-CLCB) relative to conventional extractants (Bray-1 and Olsen) in...
