 en Effect of Inorganic Fertilizer on the Microbial degradation of Diesel Polluted Soil in Abeokuta, Nigeria
OBUOTOR, T. M.; AKANDE, O. A. & BADA, B. S.

Abstract

The effect of Inorganic Fertilizer (IF) on the microbial degradation of diesel polluted soil in Abeokuta was assessed by collecting Top soil (0 – 15 cm depth) from diesel polluted site of Information and Communication Centre, Federal University of Agriculture, Abeokuta, Nigeria. Inorganic fertilizer was added to the polluted soil in the ratio: 0:1 (control), 1:1, 2:1 and 3:1. Microorganism identification, Soil Organic Carbon (SOC) and Total Petroleum Hydrocarbon (TPH) were determined using standard methods. Data obtained were subjected to descriptive and inferential statistics. Microorganism identified were Pseudomonas aeruginosa check for this species in other resources , Proteus vulgaris check for this species in other resources , Enterobacter check for this species in other resources sp., Bacillus check for this species in other resources sp., Klebsiella check for this species in other resources sp., Saccharomyces check for this species in other resources sp., Candida check for this species in other resources sp., Fusarium check for this species in other resources sp., Trichoderma check for this species in other resources sp., Neurospora check for this species in other resources sp., Penicillium check for this species in other resources sp., Alternaria check for this species in other resources sp., Aspergilus niger check for this species in other resources , Aspergilus flavus check for this species in other resources , and Aspergilus oryzaeas check for this species in other resources . pH of the soil ranged between 5.8 and 7.8. Electrical conductivity, NO3, Na, Mg and Ca contents decreased with inorganic fertilizer application. Organic Carbon, PO4 and K increased with fertilizer application. TPH degradation observed at 1:1, 2:1 and 3:1were 13.38 %, 6.45 % and 10.62 % respectively.
