Abstract

The study was carried out to examine the biostimulatory effect of saw dust and cow blood on remediation of soil polluted with spent engine oil. A completely randomized design with four treatments and three replicates each were used; three rates of saw dust and 1 litre of blood was applied to crude oil polluted soils. The results for soil physicochemical parameters showed significant variations (P < 0.05) as the levels of total organic carbon, total petroleum hydrocarbon, polycyclic aromatic hydrocarbon and nitrogen increased 2 weeks after pollution but decreased 4weeks after remediation. The bacteria count at two weeks after pollution was (1.4 × 103
to 21.07 × 103) but increased at 4 weeks after remediation to (1.67 × 103 to 80.13 × 103 ). This study showed improved soil physicochemical properties after the application of saw dust and cow blood as biostimulatory agents on the soil polluted with spent engine oil.
