Effects of red guinea corn and soybean plants growing on diesel polluted soil on the total heterotrophic and diesel degrading microbes

Effect of red guinea corn and soybean plants growing on diesel-polluted soil the total heterotrophic diesel degrading microbes were studied. Soil sample was collected from Federal Polytechnic Nekede Owerri school farm with aid a spade transported to preparation ground in clean plastic buckets where it sun-dried for 3 days. 3kg each loamy weighed out triplicates set mixed 30ml, 150ml 300ml obtain 1% (set 1), 5% 2) 10% 3) pollutions, respectively, which dispensed into perforated buckets. Each these polluted samples planted seeds Red Guinea Corn Soybean plants. Controls also up. up duplicates. During first second week plant’s growth, count, diesel-utilizing microbes, rhizosphere enumeration carried out. The results showed that count hydrocarbon-utilizing increased increasing concentration oil mixture (10%>5%>1%) both Soybeans. Similarly, effects bacterial counts found have increase percentage concentrations microbial population more than unpolluted ones. This implied by encouraging grow soils, conditions degradation contaminants can be enhanced microbiota soil.
