 From the Ag Information Network, this is your agribusiness update. A 2022 University of Wisconsin study claims U.S. farmers had converted several million acres of pristine grassland and other semi-natural areas to cropland in response to the Renewable Fuel Standard and ethanol production. Today, another Wisconsin study shows quite a different result, that between 1986 and 2018, over 30 million acres of cropland were abandoned and transitioned into grassland, pasture, forest, shrubland, wetlands, or urban areas.
