Many Iowa soybean fields have been planted two or three times after seeds struggled to emerge in crusted, dry soil following a cold spell and heavy rain. Corn plants are also showing stress from the lack of rain, though subsoil moisture remains adequate.
Replanting costs and delayed or reduced soybean stands can trim yield potential, adding modest support to soybean prices.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
After 445 past neutral weather events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.6%), and +0.7% over 20.
