Abia state (Soil quality) Palm oil effluents

The effects of Palm Oil Mill Effluents (POME) dumping on soil physicochemical parameters and selected soil plant nutrients were studied. A total of eight (8) POME dumping sites were monitored in two seasons (wet: May – September and Dry: November – March) for four (4) years. Sample collection in each site was from discharge spot of effluents, 4 and 8 meters from discharge spot along route of effluent flow. Top soil samples (0-30cm depth), subsoil samples (31-60cm depth) and bottom soil samples (61-90cm depth) were collected from each sampling spot while control samples were obtained from spots within each sampling site uncontaminated with effluents. Significantly high values (p<0.05) were observed for POME soil samples temperatures, pH (acid) and percentage moisture relative to control soils. Similarly the test soil samples cation exchange capacities and exchangeable acidities were significantly higher (p<0.05) than that obtained from control soils. Although the POME dumpsite soil ammonium ion, nitrate and sulphate ions were significantly (p<0.05) lower than those from control soil samples, while aluminium, potassium, phosphate and sodium ions were higher (p<0.05) in POME dumpsite soils. Percentage nitrogen also increased (p<0.05) in the POME dumpsite soil relative to control soils. These findings attest to a possible use of POME as a biofertilizer if properly harnessed and manage.
