Soybeans and corn fell on speculative and technical selling, with soybeans at two-month lows and December corn at a new contract low. Forecasts called for hot temperatures in key growing areas before a more moderate pattern, and the trade expects large crops.

Large expected US crops and ample corn supplies keep downward pressure on feed grain and soybean prices, though heat stress is a near-term upside risk. Argentina's tariff timing has little near-term effect on export flows.
