Soybeans were mixed on spread adjustments, with January through May contracts weak to modestly lower and the other months firm to modestly higher. Dry parts of Brazil have received rain, with the potential for more this week, but dry conditions persist in parts of South America. The rain could miss portions of Brazil and most of Argentina, while longer-term outlooks are uncertain because of the ongoing La Nina pattern. Safras e Mercado says 88.9% of Brazil’s soybean crop is planted, compared to 90.8% a year ago and 91.3% on average.
