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 r...

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...

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 w...

Restorative Effects of Amendments on Artificially Degraded Soils in the Southern Guinea Savanna of Nigeria

Adaikwu A.O*, F. K. Salako, Busari M. A., Jamiu Oladipupo Azeez

An evaluation of the productivity of degraded alfisols at Makurdi and Otobi, Nigeria, using artificial desurfacing techniques (ADT) was carried out in 2012 and 2013 cropping seasons. The study was a split-split plot experiment arranged in a Randomized Complete Block Design with three replications. The soil was desurfaced at 0 – 5, 0 – 10, 0 – 15, 0...

Heavy Metal Accumulation in Soil and Subsequent Uptake by Amaranthus (amaranthus Cruentus (l.) Irrigated with Dye Industrial Effluent

O. A. Oguntade*, Adetunji M. T, Jamiu Oladipupo Azeez

This study assessed the impacts of untreated dye effluent collected from three dyeing sites on soil heavy metal accumulation, uptake by root and accumulation in amaranthus shoot. Dye effluents collected at discharge points on the sites were diluted with fresh water at 0 %, 25 %, 50 % and 100 % concentrations. Each dye effluent concentration was app...

Heavy Metals Accumulation in Soil and Amaranthus Cruentus L Irrigated with Dye Effluent Polluted Stream Water in Abeokuta, Southwest Nigeria

O. A. Oguntade*, M. T. Adetunji, F. K. Salako, T. A. Arowolo, Jamiu Oladipupo Azeez

This study evaluated the quality of Amaranthus cruentus irrigated with dye effluent polluted stream and water from a deep hand-dug surface well (well-water). It also assessed the levels of heavy metals including Manganese, Iron, Copper, Zinc and Chromium in soil and amaranths irrigated with the waters in two dry seasons. The results showed that the...

Effect of Land Use and Soil Depth on Soil Phosphorus Fractions

Jamiu Oladipupo Azeez*, Aloba F. O, Ogunwale O. V, Oguntade O. A., Adekunle. I. O, Amusan A. O

The aims of the experiments were to determine the effect of land use and soil depths on soil phosphorus fractions. Soil samples were taken systematically from dug profile pits at 0-20, 20-40 and 40-60 cm. Soil samples were characterized and P fractionation analyses were done in triplicates using standard procedures. Data generated were analysed usi...

Effect of Land Use on the Distribution of Heavy Metals in Abeokuta, Southwestern Nigeria

Jamiu Oladipupo Azeez*, Oladosu S.A.O, Ilori O. E, Omotosho S. M., Onasanya, O. O, Oguntade O. A.

To prevent risks of metal pollution and secure public health, the assessment of the pollutant load of different land use is germane in emerging cities. The study investigated the distribution of water, EDTA and HCl extractable Cd, Pb, Zn, Cu, Cr, Ni and Mn in soils of different land uses in Abeokuta, southwestern Nigeria. It was hypothesized that l...

Nitrogen and Phosphorus Dynamics in a Legume Based Integrated Nutrient Management System

Amusan A. O*, Adetunji M. T, Jamiu Oladipupo Azeez

This study was carried out on a tropical alfisol for two consecutive years to investigate the effect of a legume based integrated nutrient management system on the soil status of nitrogen and phosphorus. The treatments consisted of two rates of poultry manure (0 and 5 t ha-1 ), three rates of N fertilizer (0, 50 and 100 kg N ha-1 applied as urea), ...
