Fowl soil

Chicken manure could be used in bioremediation of soil contaminated with crude oil, according to a report in the International Journal of Environment and Pollution. Bello Yakubu, Huiwen Ma, and ChuYu Zhang of Wuhan University, China, point out that contamination of soil by crude oil occurs around the world because of equipment failure, natural disasters, deliberate acts, and human error. They have now shown that microbial growth promoted by the application of chicken manure to contaminated soil accelerates the rate of growth of microbes that metabolize the components of crude oil. "This could be one of several environmentally friendly ways of abating petroleum hydrocarbon pollution in the natural ecosystem," Ma and colleagues say.
