By The Associated PressSoybeans futures rose on concern that warmer, drier weather in South America may damage the crop there. Traders are also speculating that Brazil may struggle to meet demand for its exports in February, meaning that buyers may be forced to turn elsewhere to source their soybeans, said Tom Fritz, of the EFG Group, a commodities brokerage in Chicago. Bets on strong export demand for U.S. soybeans are also bolstering prices, he said. The U.S. department of agriculture will publish its weekly export sales report Thursday at 8:30 a.m. EST. "There's a little bit of a weather threat developing down in south-eastern Brazil, Argentina," said EFG Group's Fritz. "It's turned rather warm and dry for the next five to 10 days."
