ST. PAUL (AP) - Minnesota farmers are facing several challenges in shipping and storing what's expected to be the state's second largest corn crop in history.

The state's fall harvest will amount to nearly 1.4 million bushels. But the massive corn crop is pressuring grain prices, so farmers may opt to store their grain instead of sell it. Bob Zelenka, head of the Minnesota Grain and Feed Association, says farmers may run out of places to store the grain and be forced to pile it on the ground.

Experts are continuing to monitor potential problems with transporting crops since many railroads are already backed up with the shipment of oil, coal, taconite and other commodities.
