Drought since September 21 in Argentina's central farm belt has prevented planting of late-season soybeans and corn and threatens crops already sown. Farmers in Buenos Aires province, including Juan Graneros, report no meaningful rain on their fields.

Argentina ranks among the top exporters of soybeans and corn, so reduced output or delayed planting lifts Chicago futures and raises feed ingredient costs for buyers.
