* Soybeans tick up after deep losses, trade near 10-year low
* Demand from Egypt and Turkey helps support wheat prices
* Corn firm but trails advances in wheat and soybeans
(Updates prices, adds quotes; changes byline, dateline, previous LONDON) CHICAGO, Sept 19 (Reuters) - U.S. soybean futures rose more than 1 percent on Wednesday, rebounding a day after the most-active contract fell to a 10-year low as the harvest of a likely record-large U.S. crop got under way, analysts said. U.S. wheat futures rose on technical buying and concerns about tightening global supplies, while corn futures followed the firm trend. As of 1:01 p.m. CDT (1801 GMT), Chicago Board of Trade November soybeans were up 14 cents at $8.28 a bushel. The contract on Tuesday fell to $8.12-1/4, the lowest price for a most-active contract since December 2008. "Soybeans were due for a bounce, after four straight down days, probing into contract lows and a 10-year low. It's about time," said Ted Seifried, chief agriculture market strategist for broker Zaner Group in Chicago. Soybeans also appeared to drew support from world stock markets, which broadly rose for a second straight day on bets the ongoing U.S.-China trade spat would inflict less damage than feared. China is the world's biggest soybean importer. CBOT wheat rose more than 2 percent, with the December contract up 12-1/2 cents at $5.23 a bushel. Wheat firmed on a mix of chart-based buying, with the December contract nearing resistance at its 20- and 200-day moving averages, along with a pick-up in global export business that has reinforced ideas of tightening global supplies. Egypt's main state wheat buyer on Tuesday booked 475,000 tonnes of wheat for two shipment periods, and Turkey's state grain board issued a tender for around 252,000 tonnes of wheat.
Traders were also monitoring dry weather and potential for additional cold temperatures in Australia, a key wheat exporter, following possible frost damage last weekend. "There is just enough news in here that you are sponsoring a degree of short-covering," one Chicago trader said. However, he cautioned, volume in CBOT wheat futures was thin. CBOT corn futures followed wheat and soybeans higher, with benchmark December up 3-1/4 cents at $3.46-1/2 a bushel, but pressure from the expanding U.S. harvest capped rallies. "The next couple weeks are going to be rough because guys are going to be more apt to sell corn off the combine than soybeans, which is a bit of a reversal from what we have seen in recent years," Seifried said. U.S. producers are more likely this autumn to store their soybeans, Seifried said, in hopes that a resolution to the U.S.-China trade dispute or a weather problem in South America might spur prices higher.
