New way to treat lead in soil: Save $22,500 per acre

Nick Basta, a scientist in our college, has developed a new, much cheaper way to treat lead in soil (video, 2:14). Using compost and other material, it costs 75 percent less than the next-cheapest option ($7,500 an acre vs. $30,000) and can benefit cash-strapped cities. Lead in soil is a health risk to kids, especially in cities, and a snag for urban farming. Basta is shown here working in Cleveland, which SmartPlanet calls one of the most progressive cities in the U.S. for urban farming.
