The study focused on the effect of the palm oil mill effluent (POME) on the physico-chemical parameters of agricultural soil within Umuahia. The soil samples were collected from the areas where the POME was discharged. The following parameters were analyzed: particle size, organic carbon, organic matter, total nitrogen, total phosphorus, available phosphorus, exchangeable cations (Na, K, Ca, Mg), electrical conductivity. Digested samples were also analyzed for heavy metals (Cd, Cr, Ni, Cu) using an atomic absorption spectrophotometer. Results of the physico-chemical analysis showed that the discharge of POME onto the soil causes the degradation of soil physico-chemical properties and increase heavy metal contamination.

Keywords: Physico-chemical, soil, palm oil, effluent, heavy metals
