Soil pollution is a serious challenge in crude oil polluted areas in Nigeria. The cleaning of this pollutant in soil has been a major source of challenge to the polluting parties, government and residence of those areas. Bio-augmentation is a cost effective and environmentally friendly method to solve polluted soils. Biomass enhance the degradation of crude oil in soil may be an effective and friendly method to reduce or remove totally oil pollution in soil. This study was carried out to evaluate the effectiveness of using groundnut husk and poultry droppings for bioremediation of crude oil polluted soil. Crude oil contaminated soil of 200 g was divided into four portions: A, B, C and D. A was treated with 70g chicken dropping and 30g Groundnut husk, Portion B was treated with 30g of chicken droppings and 70g of groundnut husk. However, C was treated with 50g of chicken droppings and 50g of groundnut husk and D was the control. Degradation of crude oil polluted soil was observed for 42days. The results revealed that the rates of crude oil biodegradation increased gradually with time and maximum amount lost was 81.81% in soil sample “A” containing 70% chicken droppings and 30% groundnut husk, 71.19% degraded in the sample “B” containing equal percentage of chicken droppings and groundnut husk (50%:50%) and 60.77% in the sample “C” containing 70% groundnut husk and 30% chicken droppings after a period of 6 weeks respectively. In concluded chicken droppings showed better degradation of soil than ground nut husk.
