Chicago Board of Trade (CBOT) grains futures closed mixed on Wednesday with corn and wheat posting further losses due to favorable weather and ample stocks.

The most active corn contract for December delivery fell 2 cents, or 0.54 percent, to 3.665 dollars per bushel. December wheat delivery went down 9 cents, or 1.97 percent to 4.47 dollars per bushel. November soybeans rose 1 cents,or 0.11 percent, to 9.2525 dollars per bushel.

CBOT brokers reported that funds sold 6,000 contracts of corn, 3,700 contracts of soybeans, and 4,700 contracts of wheat during the session.

Funds managers returned with more sales of contracts, which pressured corn, wheat and soybean futures to new lows.

Rains in northern plains and Iowa are expected to boost crop prospects, thus dragged down the prices of corns and wheat,said analysts.

News that Egypt bought 355,000 metric tonnes of wheat on Wednesday, mostly from Russia, put additional pressure on CBOT wheat prices.

Soybean prices reversed higher after traders learned that Chinese importers had signed letters of intent to buy 3.8 million metric tonnes of U.S. soybeans in Omaha, Nebraska.
