USDA's Grain Transportation Report estimates that as of September 1, 2020, farmers and commercial facilities held 7.6 billion bushels of grain, down 8% from last year. NASS projects 19.4 billion bushels of new-crop corn, soybeans and sorghum in 2020/21, up 11%.
Harvest timing and storage levels shape rail and barge demand for grain, and a larger new crop points to heavier shipping needs in coming months.
