CHICAGO, May 16 (Reuters) - Chicago Board of Trade corn futures sank on Friday on ideal growing and planting conditions in the U.S. Midwest, traders said.
Rains in the Midwest are set to expand from Sunday through Wednesday to recharge moisture supplies and aid crop growth, according to Commodity Weather Group.
The rains were preceded by dry weather, which allowed farmers to quickly seed their corn crop.
However, brisk export demand has kept a bottom on corn futures.
CBOT July corn CN25 closed 5 cents lower at $4.43-1/2 per bushel. December corn CZ25, which represents the crop that farmers will harvest this autumn, slipped 3-1/4 cents to end at $4.35-1/2 per bushel.
