Water sources could become contaminated as more corn is grown for biofuel production, researchers from Purdue University reported. The study, which focused on Indiana, found that water sources near fields that use continuous-corn rotations contained more nitrogen, phosphorous and fungicides than sites that practice corn-soybean rotations.
