Soybeans pressured by rains in Argentina, record Brazilian crop. Chicago soybean futures edged lower, with the market trading near its lowest in almost 11 weeks as forecasts of rain in Argentina’s drought-hit oilseed growing areas weighed on prices. Rains that fell on Argentina’s main farm belt over the weekend brought relief to parched soybean. The Chicago Board of Trade most-active soybean contract slid 0.1 percent to $9.61 a bushel.
