They help the region’s clay soil drain faster and produce higher crop yields. But for years, Lake Champlain has had high levels of phosphorus pollution, which can result in toxic blue-green algae blooms, and farm runoff is one of the primary contributors.</p><p>Now scientists are trying to figure out whether there’s a link between tile drainage and phosphorus pollution.</p> Tue, 10 Sep 2013 10:54:05 +0000 Sarah Harris 42563 at http://wrvo.org Research examines links between runoff and phosphorus pollution
