The biostimulation potentials of oil palm bunch ash (OPBA) and poultry manure (PM) for the remediation of crude oil polluted soil were comparatively investigated on a 70 Days study period. The hydrocarbon polluted soil was supplemented with different weights (200g and 250g) of OPBA and PM treatments singly and in combination. Analyses of composite samples for both physicochemical and microbiological parameters were carried out using standard methods. The results showed that addition of OPBA and PM significantly modified the soil physical, chemical and biological properties. The phenotypic and phylogenetic analyses of 16S and ITS rRNA gene sequence isolated showed that they are related to members of the species Priestia megaterium, Bacillus aryabhattai and Penicillium javanicum, Aspergillus alabamensis respectively. Of the treatments employed in this study, PS+125gOPBA+125gPM and PS+250gOPBA options presented the optimal levels with potentials as the cost effective biostimulants for remediation of crude oil impacted media.
