Corn Futures Slide as Strong Planting Weather Mulled Corn for May delivery fell 1.8% to $5.35 1/4 a bushel on the Chicago Board of Trade on Wednesday, with grains traders anticipating good spring weather ahead enabling a large planting season for U.S. corn. Wheat for May delivery fell 1.5% to $6.56 a bushel. Soybeans for May delivery fell 0.4% to $14.07 1/4 a bushel. "Corn was down ... on talk of good early planting weather and lack of fresh export demand, plus lower Argentine export premiums," said Charlie Sernatinger of ED&F Man Capital. A record 182 million acres of corn and soybeans is expected to be planted by farmers this year, although the USDA will update this figure with its Prospective Plantings report at the end of the month.
