Low water on the Mississippi River slowed barge traffic, and grain is backing up at local elevators. The Coast Guard reopened closed stretches near Memphis and Stack Island after dredging, which had halted about 100 towboats and 2,000 barges.
Arkansas soybean harvest is behind last year and the average, and elevators are turning farmers away.
Shipping constraints raise barge freight and delay grain movement, which widens local cash basis and pressures farm-gate soybean prices. Storage limits can force sales at lower prices during harvest.
