Remediation Potentials of Spent Milled Maize and Cowblood on Agricultural Soil Polluted with Crude Oil

In Nigeria especially in Niger Delta region, soil pollution and degradation such as crude oil spillage is of a paramount concern. As such, the only strategy to remediate such soil condition in Niger Delta region is through the application of organic nutrient amendment material such as Cowblood and spent milled maize. Cow blood and spent Milled Maize is easy to find and has a great potential as raw materials for Boiremediation as shown in this study carried out. Three rather of crude oil (0,10 and 15ml) and three rates of Spent Milled Maize (0, 2 and 3g) were used respectively. It comprises of the three-treatment replicated Nine Times, for a total of Twenty-Seven pots with each pot containing 5kg of soil. Microbial population and physico chemical properties of soil were determined after pollution and at the end of the experiment the result for physico chemical properties of the soil indicates and increase across most of the soil Parameter analysed such as Nitrogen, Potassium, Available Phosphorus etc. Also, there was a notable reduction (decrease) in the level of total hydrocarbon found in the soil. There was also an increase in the microbial population (bacteria Count) from 2.3X10’3 in the control to 3.5X10’6 in souls polluted with 15ml of crude oil,3G of Spent Milled Maize and 3ml of Cowblood. The genus of bacteria identified in the Course of this study Pseudomonas, bacullus, Norcardia and Proteus species were found in the soil samples.
