Yields above expectations There will be ‘piles and piles’ of surplus, says analyst
CHICAGO, Ill. (Reuters) — The giant corn harvest that is about to hit full stride in the U.S. Midwest looks set to overwhelm storage and pile up outdoors, which raises quality issues and makes it hard to keep supplies moving.
This year’s record corn crop of 14.4 billion bushels would fill up 60 percent of the country’s grain storage of 24 billion bu.
Combined with record soybean crop and hefty harvests of other grains, including spring wheat, it means 20 billion bu. of new crops will be looking for storage.

federal government proposed several months ago to increase the compensation rate from 80 to 90 per cent and double the maximum payment from $3 million to $6 million
And that would be on top of the 3.5 billion bu. reported in storage as of Sept. 1 by the U.S. Department of Agriculture.
Hal Reed, chief executive officer of the Andersons Inc., a major grain handler in Toledo, Ohio, said his company is already piling grain at its elevators in Tennessee and other mid-south states even before harvest moves north into the main corn belt.
“We still believe the actual yields will continue to grow from where USDA has them at now. The corn crop is as good as any I’ve ever seen,” Reed said.
Surplus corn is often held in temporary piles of 200,000 bu. or more covered with tarpaulin while waiting for trains or barges to ship the grain out. However, transportation has been hard to find this year as shale oil competes for space on rails.
“There are going to be piles and piles. The stampede will start about Oct. 20,” when on-farm storage in Iowa should be about full, said Charles Hurburgh, a grain quality specialist at Iowa State University.
The challenge will be to preserve the quality of the crop left on the ground and keep it safe for later use.
Grain merchandisers need to make sure corn is dried to about 13 percent moisture before storing. It also needs to be properly aerated while on the ground to prevent spoilage and stop toxins from growing.
Soybeans, which are valued for their oil content and harvested before corn, are more likely to be sold straight off the field than corn, which is hardier and can be “air dried” so that farmers don’t have to pay to dry it.
“As much as people say you can put corn away at 17 to 18 moisture, put the aerators on and keep it, experience tells that doesn’t always work out well,” said Joe Christopher, a Nebraska merchandiser.
Grain merchants are expected to force many farmers to accept “deferred pricing” contracts, which allow merchants to take ownership of the grain so that they can better manage their space.
However, there are still problems moving the piles. Rail freight rates are soaring because of competition, not just among grain shippers but also from shale oil in many grain regions, especially the Dakotas.
“It gets clogged up at the farmer, it gets clogged up at the elevator, it gets clogged up at a whole bunch of places. It’s going to be a real problem,” said Stephen Nicholson, an analyst at Rabobank, a major farm lender.
