Water levels in the Lower Mississippi River have dipped unusually low for a third year in a row, restricting how much grain can be transported downstream as harvest season gets underway. If levels keep dropping and barge traffic slows navigation, some Illinois farmers worry that soybean and corn prices will drop too or that they won’t be able to get fertilizer from downstream to begin prepping their fields for next year’s crops. Concerns are bubbling up among farmers after a good growing season, since those who depend on river transport might be stuck with their product for longer than anticipated. “Especially with a potential record number of crops coming in and no place to go,” said Jared Gregg, a seventh-generation soybean and corn farmer in Piatt County west of Champaign.
