Abstract

In this field study conducted at the Teaching and Research Farm of Department of Agricultural Education, Federal College of Education(Technical) Omoku, Rivers State Nigeria to determine the bioremediation potentials of rumen- based wastes (RBW) on crude oil polluted soils, Cassava (Manihot esculenta Crantz.) was used as test crop. The soil was contaminated with Bonny Light crude oil obtained from OB/OB Nigeria Agip Oil Plc. Fresh RBW was obtained from an abattoir in Omoku, Rivers State. Cassava stems were obtained from the NAOC Green River Project, Obrikom. The soil was pulverized, made into raised seed beds, then contaminated with crude oil at the rates of 0litre m-2(Control) , 1.5litre m-2 (Mild), 3litre m-2 (Moderate) and 4.5litre m-2 (Severe). Two weeks after contamination RBW were applied as mulches at the rates of 0, 2, 4 and 6kg/m-2. Results show that RBW increased nickel, lead and copper accumulations in cassava leaf and tuber. It is recommended that RBW should not be used in augmenting crude oil polluted soils as it enhanced accumulation of heavy metals in cassava leaf and tuber.
