The Illinois Soybean Association says about two-thirds of Illinois soybeans are exported and about half leave through the Gulf via the Mississippi and Illinois rivers to New Orleans. It notes that barges carry about 52,000 bushels each, more than containers, while rail and containers suit smaller, faster orders.
The reliance on Gulf barge logistics shows how river conditions affect Illinois soybean basis and export competitiveness. It is a background explainer rather than a new market-moving event.
