DTN reports that a brief break in La Niña brought generous November rain to Argentina, improving soil moisture for corn and soybeans. Forecasters expect the typical La Niña dry pattern to return, while southern Brazil has received only about half its normal early-November rainfall.
Renewed dryness in Argentina and southern Brazil threatens soybean and corn output from South America, which tends to support soybean meal and corn prices as export supply tightens. Southern Brazil's shortfall adds to the risk.
