Corn futures at the Chicago Board of Trade were lower early on Tuesday amid active harvest of a big US corn crop and on spillover pressure from a tumble in soya, traders said.
At 10:08 am CDT (1508 GMT), CBOT corn was down 1/2 to 1-3/4 cents per bushel. December was down 1-1/2 at $2.02-1/4 per bushel.
Pit sources said Man Financial and DT Trading each sold 200 December.
Traders and analysts said corn futures continued to be anchored by the aggressive combining of a big US corn crop. There are forecasts for this year's output to rank second only to last year's record large crop of 11.8 billion bushels.
The US Agriculture Department late Monday said 49 percent of the US corn crop had been harvested, in line with trade estimates for 45 to 50 percent.
