Excess rain in central and northern Brazil is hampering harvest of second-crop soybeans and corn, while Argentina faces drought that is cutting soybean and corn yield potential. Only 17% of Brazil's soybeans and 25% of its corn had been harvested or sown, and Rio Grande do Sul's drought is also reducing soybean potential.
Yield losses in Argentina and delayed Brazilian planting together threaten South American supplies, which supports soybean and corn prices.
