T HE potential of cow, pig and poultry dung for the bioremediation of in-situ crude oil contaminated soil for a period of 3-15 days at different soil and dung ratios were the objectives of this investigation.Using simulated soil, 200 g were measured into polyethylene bags labelled A,B,C,D,E, F and G. Soil physicochemical parameters such as particle size distribution, pH, organic carbon, organic ma...
