CHICAGO, Feb 16 (Reuters) - Chicago Board of Trade soybean futures rose on short covering on Friday, while corn futures consolidated after setting a three-year low for the third consecutive session under pressure from large supplies, analysts said.

Wheat futures extended losses to a 2-1/2 month low.

Traders digested supply and production data issued by the U.S. Department of Agriculture this week and also adjusted positions before the three-day holiday weekend. The CBOT will be closed on Monday for Presidents Day.

"The soybean market is quite oversold," said Tomm Pfitzenmaier, analyst for Summit Commodity Brokerage.

Most-active CBOT soybeans were up 9-3/4 cents at $11.72 a bushel by 11:40 a.m. CST (1740 GMT), after falling on Thursday to the lowest price since December 2020 at $11.60-1/4.

CBOT corn was flat at $4.17-3/4 a bushel, after touching its lowest level since December 2020 earlier on Friday at $4.16-1/4. Wheat was down 5 cents at $5.62 a bushel and hit its weakest price since Nov. 28 at $5.60.

The USDA's chief economist said this week that U.S. soybeans would face slowing demand from top importer China and steep competition from South America. Beneficial rain for crops in Argentina and Brazil have tempered worries about heat and drought losses.

"The better weather in South America, along with declining U.S. exports, leaves traders with little reason to buy soybeans in the short run except for short-term profit-taking," Pfitzenmaier said.

The USDA said on Thursday that U.S. soybean ending stocks would climb to 435 million bushels in 2024/25, the highest since 2019/20, and U.S. corn stocks would balloon to 2.532 billion bushels, the most since the 1987/88 season.

Market reaction to the projections may fade as participants await clearer evidence of U.S. planting trends and look ahead to more detailed 2024/25 forecasts, Commerzbank said.

"When prices are low, corn is a high-cost crop," said Jim Gerlach, president of brokerage A/C Trading. "You're going to see some of those marginal acres drop."
