The centuries old practice of plowing farm fields, which has fallen from favor in recent years, is not only time consuming but also harmful to the environment. Research by Boston College’s Geology and Geophysics Department has determined that plowing releases 41 percent more carbon into the atmosphere than no-till farming. Carbon, incorporated into greenhouse gases, contributes to global warming. No-till farming also produces 15 percent more food on the same acreage then conventional farming, which is important for feeding a growing world population.
