The enduring match of farms and plows seems destined for a breakup as more farmers incorporate no-till farming practices. "The demise of the plow and other tools that turn the soil is a rare good-news story in these depressing times for Planet Earth," writes Dana Milbank in his Washington Post opinion. "Modern, mechanized tillage [is] an ecological disaster, killing all that was alive in the soil while worsening erosion and runoff."
Over the past five decades, farmers realized how much harm tilling was doing and began to step away from their plows. Milbank explains, "In 1973, 82.2% of U.S. cropland was managed by conventional tillage, and only 2% was managed by 'no-till' methods, with the remaining 15.8% using reduced tillage. Half a century later, only 27% of U.S. cropland uses conventional tillage, with 38% now using no-till and 35% using reduced tillage."
Part of the shift to no-till includes a change in farming culture. Milbank adds, "If Big Ag destroyed the soil with its heavy use of chemicals and monster tilling equipment, the new agriculture is about building soil health so that it can nurture as it once did." The no-till resurgence takes its lessons from "traditional farming methods that existed for centuries before chemical fertilizers and pesticides. . . . and newer technologies, such as drilling seeds into the soil to preserve the soil’s structure."
John Piotti, head of the American Farmland Trust, which has been working on regenerative practices with big and small farmers and food companies including Land O’Lakes and General Mills, told Milbank, "It’s a very good trend — an excellent trend . . . . It’s really about whether we’re going to have a planet we can live on.”
