This study aimed to investigate the accumulation of heavy metal on oil palm plantation soil fertilized with palm oil mill effluent POME. The research appraised the extent of contamination in oil palm plantation soil in Ikpoba Okha local government area of Edo state Nigeria. Soil sample were collected from different soil depth ranges 0-15cm, 15-30cm, 30-45cm, 45-60cm and 60-70cm of POME treated soil at five locations (2-6) and the control location 1 within oil palm plantations. The concentrations of the heavy metals (Cu, Mn, Zn, Ni, Pb, Cd, Cr, As, Hg) were analyzed using the atomic absorption spectrometry (AAS). The results show that the application of POME as fertilizer led to increased concentration of heavy metals. Significant difference at (p < 0.05) level in concentration was obtained across the different depths of the treated locations for the metals compared to the background location. However, As and Hg were not significantly different between the POME treated soil and control location. The impacts of POME treatment have greater effects on the concentration of the essential metal (Cu, Mn, Zn, Ni) compare to the non-essential metal (Pb, Cr, Cd, As, Hg). The concentration of the metals was below the permissible limits of regulatory standards. The increase concentration of the essential metal could have potential implications of soil contamination due to accumulation over time. The soil had contamination factor and pollution load index of low to moderate contamination and pollution. The control location 1 had the closest similarity with the location 6. The study proposed recommendation for POME usage as organic fertilizer in agricultural soil but with close monitory.}, subject = {POME; Schwermetallen; Heavy-metal; Contamination; Accumulation; Palm{\"o}lm{\"u}hlenabw{\"a}sser; Kontamination; Akkumulation; Boden; Benin City; {\"O}lpalmenanbau; Organisches D{\"u}ngemittel; Schwermetallbelastung}, language = {en} }
