The fields of corn and soybeans at Birmingham Farm, owned by Kansas City, Mo., look like the crops at any other farm.

But unlike most farmland, these fields are fertilized with biosolids produced by the city’s wastewater treatment process.Each year Birmingham Farm uses about 55,000 dry tons of biosolids, sometimes called “sewage sludge,” from the city’s main wastewater treatment plant, Blue River. Its history stretches back to the 1970s when the city first started applying biosolids from a smaller treatment plant to 300 acres of farmland. Sewage sludge turns a profit for Kansas City – Waste & Recycling News
