SINGAPORE, Sept 19 (Reuters) - Chicago corn and wheat futures lost more ground on Tuesday, falling for a second consecutive session in the face of abundant global supplies.
Soybean prices ticked up after closing marginally lower on Monday.
* The Chicago Board of Trade most-active corn contract had slid 0.1 percent to $3.51 a bushel by 0109 GMT, while wheat gave up 0.3 percent to $4.42 a bushel.
* Soybeans added 0.1 percent to $9.69 a bushel.
* The U.S. Department of Agriculture (USDA) in its weekly crop progress report said the U.S. corn harvest was 7 percent complete, behind the five-year average of 11 percent.
* The soybean harvest was 4 percent complete, close to its average pace of 5 percent, the agency said after the market closed on Monday.
* U.S. and global supplies of corn remain ample. The USDA last week forecast a U.S. corn yield of 169.9 bushes per acre and 2017-18 ending stocks at a hefty 2.3 billion bushels.
* In the wheat market, the focus is on a tender issued by Egypt's General Authority for Supply Commodities to buy an unspecified amount of wheat from global suppliers for shipment from Oct. 21-31. Results were expected later on Tuesday.
* Wheat exporters from the Black Sea region and Europe have in recent years won a bulk of the tender business coming from Egypt, the world's biggest importer.
* Soybean prices have been underpinned by strong demand. The USDA through its daily reporting system said on Monday private exporters sold a total of 387,000 tonnes of U.S. soybeans, including 261,000 tonnes to China, the world's top soy buyer.
* Money managers reversed their six-week selling streak across Chicago-traded grains and oilseeds in the week ended Sept. 12 even amid some relatively bearish figures from the USDA. (http://reut.rs/2x3fvA1)
* Asian shares wavered on Tuesday, bolstered by record highs on Wall Street but hobbled by uncertainty as traders waited on a Federal Reserve meeting for clues on U.S. monetary policy.
