GRAINS-Chicago soybeans rise; corn, wheat ease ahead of key reports

BEIJING, Sept 9 (Reuters) - Chicago soybeans extended gains into a second session on Tuesday, supported by lower U.S. crop ratings and a weaker dollar, although a lack of demand from top buyer China continued to weigh on sentiment.

Wheat and corn eased as traders positioned ahead of a key U.S. supply and demand report.

FUNDAMENTALS

* The most active soybean contract on the Chicago Board of Trade (CBOT) Sv1 added 0.02% to $10.34 per bushel as of 0029 GMT.

* Wheat Wv1 eased 0.05% to $5.23-4/8 a bushel, while corn Cv1 lost 0.12% to $4.21-2/8 a bushel.

* Traders are awaiting the U.S. Department of Agriculture's (USDA) global supply and demand reports on Friday for 2025-26 global ending stocks estimates for wheat, corn and soybeans.

* U.S. corn and soybean crop conditions eroded for a second straight week last week, the USDA said, although its ratings of crops in good to excellent shape did not decline as much as some analysts had predicted in a Reuters poll.

* The U.S. spring wheat harvest reached 85% complete by Sunday, up from 72% a week earlier and slightly above expectations.

* Soybeans remained under pressure from a lack of Chinese demand. China's soybean imports notched their best August on record, as buyers snapped up large volumes from South America amid ongoing Sino-U.S. trade tensions.

* Commodity funds were net buyers of CBOT corn, wheat and soybean futures, traders said. COMFUND/CBT

MARKET NEWS
