Studies on the effects of burnt naira ash on soil properties. Natural Products Research Bulletin (An International Scientific Research Journal),1(2), 034 - 040http://nprbulletin.com/ documents NP0010.pdf.https://repository.futo.edu.ng/handle/20.500.14562/1465The article is an original researchStudies on the effects of burnt naira ash on soil properties was carried out using samples collected from the Central Bank of Nigeria dump site and the adjoining environment. The samples were subjected to microbial, physical and chemical analyses. Concentrations of heavy metals (Ni, As, Cd, and Hg) were also determined using Atomic Absorption Spectrophotometer (AAS). Microbial counts ranged from 60 CFU/g to 205 CFU/g with the isolation of the following bacteria species: Acetobacter sp, Epulopiscium sp, Shigella sp, Staphylococcus sp and Fusobacterium sp. The fungal isolates were Penicillium sp, Rhizopus sp and Aspergillus sp. The soil physical and chemical parameters analyzed, showed relative increase in comparison with the sample from the adjoining environment. While the pH of the control sample tended to be acidic, the samples from the dump site tended to be basic. The Chi-Square value of a = 0.05 for total microbial count was significant. Also, at a =0.05, the heavy metal concentration values showed significant difference while chemical and physical properties of the samples were however insignificant at a = 0.05. Burnt Naira ash affected the microbial, some physical and chemical properties of the polluted soil.enAttribution-NonCommercial-ShareAlike 4.0 InternationalHeavy metalsconcentrationsoilnaira ashenvironmentDepartment of BiotechnologyArticle
