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...

Soil Fertility Management among Cucumber (Cucumis Sativus L.) Farmers in Ibadan, South-West Nigeria

Utibeabasi Brownson^*, OLOGUNDUDU, O. M., OMONIYI J, AdeOluwa O. O

Poor soil fertility reduces the yield, market value, and sustainable production of cucumber. This study examined soil fertility practices among cucumber farmers in Ibadan. A purposive sampling method was used to select 10% of cucumber farmers from six blocks, namely Akinyele, Lagelu, Egbeda, OnaAra, Oluyole, and Iddo in Ibadan-Ibarapa agricultural zone, Oyo State. A structured questionnaire was ad...

Microplastic Contamination Alters Soil Hydraulic Properties and Inhibits Maize Growth: A Factorial Assessment Across Contrasting Soil Textures.

EJI EJOR TANGBAN^*, OGUIKE, P. C., NNAJI, G. U., BENJAMIN, J. I.

Microplastic pollution in agricultural soils constitutes an emerging threat to food security, yet the interactive influence of soil texture and contamination intensity on crop productivity remains inadequately characterized. A 3 × 4 factorial pot experiment was conducted under controlled conditions at Bendeghe Ekiem, Cross River State, Nigeria, to evaluate the combined effects of high-density poly...

Comparative Mineralogical Analysis of Epigeal and Arboreal Termite Nests using Modern Analytical Techniques

Olushola Sunday Ayanda, Sharhabil Musa Yahaya^*, Omolola Helen Aremu, Aminu Abdullahi, Mohammed Adewumi Abdulrasak, Sa’adatu Eri Mohammed, Naseer Inuwa Durumin Iya, Augusta O. Mmuoegbulam, Abdulsalam I. Galadima, Micheal Abiodun Oluyide, Folahan A Adekola, Simphiwe M Nelana, Michael J Klink

Termites are generally known to be destructive to woody materials and are of benefit to agricultural sector as they improve the fertility of soil and recycle organic matter. Termite nests such as arboreal, epigeal, hypogeal amongst others are being built by termites and have received great attention due to its diverse complex architectural structures and its utilization by researchers for diverse ...

The vertical mobility of nitrogen with poultry and sheep manures amendment on degraded Ultisols in Owerri, Southeastern Nigeria

HABEEBAH SAKA^*, Bethel Ugochukwu Uzoho, Solomon Oladimeji Olagunju, Musiliat Mopelola Onaolapo

A randomized complete block design experiment was conducted for two years, two locations per year and three months per location with three replications. The rates of dried, milled pure poultry and sheep manures incorporated per location at the onset of the research were 0, 30 and 60 % N. Initial soils and manures were analyzed for macro nutrients. Soil samples collected weekly, bi-weekly and month...

Occurrence of multi-class pesticide residues in soils of selected farmlands and farmer’s household surroundings in the southwestern part of Oyo State, Nigeria

Shade Akinsete^*, Ibiwumi K. Saliu

The indiscriminate use of pesticides for crop production in Nigeria has led to contamination of the environment. Specifically, soil contamination from pesticide residues, including banned compounds raises serious public and environmental health concerns. However, very little is known about the occurrence of pesticides in Nigerian soils. Therefore, this study investigated the occurrence and concent...

Enhancing Soil Quality and Sustainable Agriculture: A Review of Black Plum (Syzygium cumini) for Soil Amendment and Productivity

AKANBI Olorunfemi Sunday Ojo^*, Isaac Kayode Oyewusi, Adegbala, A. A, Nduka B. A., Ipinmoroti, R.R.,

Jamun (Syzygium cumini), widely known as black plum, is a highly adaptable fruit-bearing tree with exceptional nutritional, medicinal, and ecological advantages. Despite its resilience in tropical and semi-arid regions, especially in areas like Northern Nigeria, its integration into formal agricultural systems remains minimal. This review synthesizes current findings on the plant’s agronomic trait...

Assessment of Soil Organic Matter Determination Techniques in Tropical Soils: Correlation Among Four Methods as Indicators of Plant Growth Potential

Toyin Blessing Odelana^*, Adedoyin Adepoju, Oladele Abdulahi Oguntade, Babajide Saheed Kosemani, Adebanke Ayooluwa Olubode, Jamiu Oladipupo Azeez

Soil organic matter (SOM) is a key indicator of soil fertility, yet variability among analytical methods limits its reliable interpretation, particularly in tropical soils. This study evaluated four SOM determination methods—Walkley–Black (WB), loss on ignition (LOI), colorimetric (COL), and hydrogen peroxide (HP)—and examined their relationships with maize growth under contrasting parent material...
