CHICAGO, Aug. 2 (Xinhua) -- Chicago Board of Trade (CBOT) agricultural futures closed mixed on Thursday, with wheat rising further on declining supply and soybeans falling amid trade tensions.

The most active corn contract for December delivery rose 1.75 cents, or 0.46 percent to settle at 3.8125 dollars per bushel. September wheat went up 2.25 cents, or 0.4 percent to close at 5.605 dollars per bushel. November soybeans were down 4.25 cents, or 0.47 percent to settle at 8.975 dollars per bushel.

Concerns over flared-up trade tensions between the United States and China continued to drag down the oil seed prices, which fell back below the nine-dollar-per-bushel level again.

Grant Kimberly, marketing director of Iowa Soybean Association, told Iowa Radio from a European market tour that other countries can hardly offset all the impact after China started to shun U.S. soybeans amid trade tensions.

CBOT wheat rose significantly amid rumors that Ukraine is considering an export tax or ban on its wheat exports, as extreme weather conditions led to declining crop yields.

A later denial relieved the panic in market. Still, CBOT wheat prices have reached the highest level since mid-July 2015.

CBOT brokers reported that funds bought 6,000 contracts of wheat and 5,400 contracts of corn, while selling 4,500 contracts of soybeans. Enditem
