Corn is falling after U.S. farmers planted record amounts of corn last week, easing concern that earlier delays to planting would harm this year's crop.
July corn fell 9.5 cents, or 1.5 percent, to $6.40 a bushel.
The earlier in the season that corn is planted, the less susceptible the crop is to weather problems later in the year. Planting had been delayed by cold weather.
