CHICAGO, March 2 (Reuters) - U.S. soybean futures rose on Thursday, extending their rebound from the one-month low hit this week on a round of technical buying, traders said.
"I think we got too cheap too fast and we are seeing a technical recovery," said Scott Harms, Ag risk specialist at Archer Financial Services.
Wheat futures also were firm, as renewed questions about a Black Sea grain export deal supported prices after Russia said the West was burying the deal.
"The trade deal has not been extended and the talks do not seem to be going smoothly," Harms said.
But corn futures ended weaker after trading in both positive and negative territory. Traders expressed disappointment in the recent export pace of corn.
Export sales of corn in the week ended Feb. 23 fell to 598,100 tonnes from 848,725 tonnes the prior week, according to U.S. Agriculture Department data. That was near the low end of market expectations.
Chicago Board of Trade May soft red winter wheat futures settled up 2 cents at $7.12-3/4 a bushel and CBOT May corn was 2 cents lower at $6.33-3/4 a bushel.
Russian Foreign Minister Sergei Lavrov on Thursday accused the West of "shamelessly burying" the trade deal that allows for grain shipments from key Black Sea ports in Ukraine, the RIA Novosti news agency reported.
His ministry had already said on Wednesday that Russia, one of the world's largest wheat exporters, would extend the deal only if it took the interests of Russian agricultural producers into account.
CBOT May soybeans gained 15 cents to $15.09-1/4 a bushel.
Cash market strength added support to soybean futures, with traders saying that five straight days of declines that culminated in the futures market dropping 2.2% on Tuesday had sparked buying interest from end users.
