Did you ever wonder what chicken poop is good for? A study last month Aug, 2008 shows that shooting ranges in Japan have extremely high levels of lead in the soil. To get rid of this, they developed a method of remediating the contamination by mixing the soil with chicken poop to reduce the bad environmental impacts from the lead.
The study (published in the Journal of Environmental Quality this past month, and last year at the Soil Science Society of America) demonstrated that the amendment reduced the toxicity characteristic leaching by 90%. It also showed that levels were reduced even further when plants were grown in the amended soil.
