Abstract
Remediation of crankcase oil contaminated soil with different sources of manure was studied using randomized complete block design with four treatments which were replicated five times. Oba super Π hybrid variety of maize was used as a test crop. Results showed significant (P<0.05) treatment effect on aggregate stability, gravimetric moisture content (GMC), available phosphorus, calcium and cation exchange capacity (CEC) as well as plant height and grain yield of maize relative to control. Significantly (P<0.05) higher aggregate stability, GMC, Calcium and CEC were obtained in plots receiving a combination of poultry droppings and NPK fertilizer compared to other sources of manure and control. Aggregate stability, GMC, Ca, CEC and organic carbon were higher by 12, 47, 75, 66 and 20% respectively in plots amended with combination of poultry droppings and NPK fertilizer when compared to the control. Grain yield of maize was 44, 36 and 40% higher in plots amended with combined poultry droppings and NPK fertilizer compared to the control, poultry droppings and NPK fertilizer amended plots. Remediation of crankcase oil contaminated soil could be achieved through manure amendment for increased and sustainable productivity.
