ARS scientists, working with NRCS and universities, have done the research that has encouraged farmers to largely put away the moldboard plow and switch to conservation tillage on about 40 percent of U.S. planted acres. We store seed wheat in a wooden grainary, we shovel starter fertilizer into the drills by hand, and we still use a moldboard plow (that always shocks no-tillers that I visit).
