EFFECT OF PHYSICOCHEMICAL PROPERTIES ON CRUDE OIL POLLUTED SOILS REMEDIATED WITH ORGANIC MANURES AND INORGANIC FERTILIZER IN BAYELSA STATE

Abstract: Soil samples were analyzed to evaluate the effect of the application of organic and inorganic amendments on the soil physicochemical properties in the remediation of crude oil polluted soils of Bayelsa State. Two (2) crude oil spilled locations, Imiringi in Ogbia Local Government Area with latitudes 4. 8519 N and longitudes 6.3745 E and Koloama in Southern Ijaw Local Government Area with latitudes 4.582222 N and longitudes 6.064722 E respectively were selected for this research. Soil samples were collected at a depth of 0 – 30 cm, bulked for pot experiment in the screen house. Five (5) kilograms of soil were weighed into twenty-four (24) plastic buckets of seven (7) liters each for Imiringi and Koloama, making a total of forty-eight (48) plastic buckets used. The experimental design was a 2 x 8 factorial experiment laid out in a Complete Randomized Design (CRD) replicated three times. Results obtained were subjected to statistical analysis of variance using the Tukey’s Test to separate means of significant difference at 5 % probability level. The amendment materials used were organic manures [cow dung (CD) and poultry dropping (PD)] inorganic fertilizer (NPK) and their combinations (CD + PD, PD + NPK, NPK + CD and CD + PD + NPK) on the soil physicochemical properties in the crude oil polluted soils. The study shows that Imiringi soils were significantly different from Koloama soils. Imiringi soils are sandy loam while that of Koloama soils are sandy clay loam. The high significant difference between the locations and among the treatments on the soil physicochemical properties in the study areas at 30 days, 60 days and 90 days respectively, indicates that the application of these amendment materials was effective.
