Southern Brazil has been notably dry, with precipitation 60 to 80% below normal and crop losses to corn and soybeans reported. Central Brazil has better soil moisture, and Argentina's drier conditions favor corn and soybean harvest progress.
Southern Brazil crop losses reduce export supply of corn and soybeans, supporting prices, while Argentine harvest progress adds offsetting supply.
