WARNING! Sewage sludge is toxic. Food should not be grown in "biosolids." Join the Food Rights Network.

MetroGro is a Madison, WI product sold as fertilizer but made from sewage sludge.[1] Hundreds of communities across the U.S. sell toxic sludge products that are typically renamed biosolids and sold or given away as "fertilizer" or "compost" (and often even labeled or marketed as "natural" or "organic").

According to one website:[2]

"The city of Madison, Wisconsin produces an anaerobically-digested biosolids product, called MetroGro, that is marketed to local agriculture. Every year, about 30 million gallons of MetroGro are sold to fertilize 3,000 to 4,000 acres of farm land. More that 30,000 acres of private farm land are enrolled in the MetroGro program. MetroGro is delivered to the farm sites in 6,000-gallon semi-tanker trucks and the biosolids are applied using 3,500-gallon application vehicles which inject the product into the soil. MetroGro is applied primarily to fertilize corn, soybeans and alfalfa."
