Impact of Mining on Heavy Metal Concentration and Soil Chemical Properties in Soils Sorrounding a Mining Site in Ebonyi State⸴ Nigeria

Akinmutimi A.L.*, OlughuF.N., Nwangwu B.C

Field and laboratory studies were done to evaluate the effect of land use types on selected physical and chemical properties of soils in Umudike, southeastern Nigeria. Five land use types were studied: rubber plantation, oil palm plantation, forest land, cassava farm land and pasture land. Under each land use system, 3 sampling points were located. Around each of the 3 sampling points, soil sample...

Different Forms of Potassium and Their Contributions Toward Potassium Uptake Under Ginger (zingiber Officinale Roscoe) Production in an Ultisol of Umudike, Southeastern Nigeria

Okeke V. N.*

To identify the quantity of optimal rates of zinc fertilizer needed for maximizing Vigna radiata yield, a greenhouse and field studies were conducted in two cropping seasons. For the greenhouse, zinc sulphate was applied at five dosages (0, 5, 15, and 20 kg ha-1) and at seven dosages (0, 3, 6, 9, 12, 15, and 18 kg ha-1) for field study. The sandy loam (SL) soil samples had modest levels of OC (1.0...

oil Microbial Activity Under Complementary Applications of Organic and Inorganic Amendments

Sangotoye S. E.*, Atere C. T., Taiwo, L. B, Olayinka A.

The research described and quantified soil consistency as cumulative consistency value (CCV) at two moisture levels for different horizons of soil profiles located on sedimentary and basement complex parent materials. It was found that the CCVs of soils formed on sedimentary deposits were between 18 and 28 while the CCVs for the soils formed on the basement complex were between 0 and 27. No signif...

Changes in Soil Physical Properties Due to Variable Weather Conditions Under Two Soil Types in South Western Nigeria

Ologunde O.H.*, Adebayo O.E., Busari M. A.

Soil physical properties changes with weather conditions over time. The degree of variation might be influenced by different soil textural classes. This study aimed at understanding the changes in soil physical with varying weather conditions under two soil textures. The research was conducted in cassava fields at the Federal University of Agriculture, Abeokuta and Psaltry International Limited, I...

Simulating Soil Nutrients Balance Using Monqi Model (monitoring for Quality Improvement) in a Rice Based Cropping System of Kano State, Nigeria

Abdulrahman B. L.*

Enhancing soil microbial properties through balanced inputs of organic and inorganic amendments are key to sustainable soil and crop productivity. A laboratory incubation study was conducted to determine microbial respiration, population and nutrient (N and P) mineralization patterns in an Ultisol amended with sole Urea at 56 kg N ha−1 or Urea (at 0 or 28 kg N ha−1) combined with 5 t ha−1 organic ...

P Sorption Characteristics in Hevea Supporting Soils of Coastal Plain Sand Origin in Southern Nigeria

Idehen, C.N.*, Bakare, A.O., Okore, I.K, Osazee, F

Phosphorus (P) is a macronutrient element that plays a number of important roles in plants and soils including Hevea brasiliensis (Natural Rubber). Adequate P nutrition in rubber will result in improved latex production, crop quality, root growth and early maturation. Thus, a study of the relevant indicator of P sorption across depth of rubber supporting soils is necessary. Therefore, this study i...
