CBOT corn ends session lower, pressured by weakness in soy and wheat

CHICAGO, March 11 (Reuters) - Chicago Board of Trade corn futures ended lower on a choppy trading session on Tuesday, as weakness in the wheat and soybean markets dragged on prices late in the day, traders said.

• CBOT May corn CK25 settled down 1-3/4 cents at $4.70-1/4 a bushel.

• The most-active corn contract on a continuous basis Cv1 earlier in the session touched the highest price seen since February 28.

• The U.S. Department of Agriculture left its forecast for domestic corn inventories unchanged in a monthly supply-and-demand report on Tuesday, surprising traders who were expecting a decline due to strong U.S. export sales.

• Traders and farmers are keeping a close eye on exports, with U.S. tariff disputes with major buyers Mexico, Canada and China threatening sales of U.S. agricultural goods.

• Market analysts said on Tuesday the USDA likely held off on changes as it waits to see whether the U.S. implements fresh tariffs and how trading partners respond.

• Pressure from what is shaping up to be a big South American crop also weighed on the corn market, said Jack Scoville, vice president at Price Futures Group.

• Brazil corn exports in March are forecast to be far higher than previously predicted, ANEC reported Tuesday.

• China's imports of U.S. corn are expected to decline following Beijing's 15% tariffs on the grain, but U.S corn only accounts for about 15% of total imports, China's agriculture ministry said.
