NuGen Energy's Marion, South Dakota ethanol plant is taking grain sorghum for the first time since 2016 because farmers could not plant corn this wet year. Post cash milo was $4.23 per bushel versus corn at $4.52.
Sorghum is a substitute for corn in feed and ethanol, so prevented corn planting shifts demand toward milo and supports sorghum prices while adding acreage that competes with corn feed use.
