A preliminary analysis of data released from the 2017 Census of Agriculture shows cover crop acreage in the U.S. has grown by more than 8% per year since 2012 and major Corn Belt states such as Iowa, Illinois and Missouri appear to be leading the charge, according to an analysis by Rob Myers, regional director of extension programs for Sustainable Agriculture Research and Education (SARE). In terms of growth rates, Iowa’s 156% increase in cover crop acres led the nation, with 973,112 acres seeded in 2017 vs. 379,614 in 2012, Illinois, Ohio, Nebraska and Missouri also led the way with increases of 100% or more, Myers says.
