A University of Minnesota planting-date survey finds that corn and soybean yields are best with planting in late April to early May. It notes that planting too early can risk frost damage and replanting, while late planting lowers yields.
This agronomic guidance does not add new supply information, so it has no meaningful effect on feed grain prices.
After 2,467 past weather events, Corn moved a median +0.1% over 5 sessions (51% higher; middle half -1.5% to +1.7%), and +0.6% over 20.
After 1,964 past weather events, Soybeans moved a median +0.1% over 5 sessions (51% higher; middle half -1.7% to +1.8%), and +0.3% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
