A University of Minnesota study maps evapotranspiration, water stress and crop water productivity in central Minnesota watersheds for 2021 to 2024 using satellite-based SEBAL methods. It also generates 30 m corn and soybean yield estimates.
This is academic research on irrigation and water management with no new supply shock, so it has no meaningful direct price implication.
After 3,207 past report events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.3% to +1.7%), and +0.5% over 20.
After 2,389 past report events, Soybeans moved a median 0.0% over 5 sessions (50% higher; middle half -1.6% to +1.9%), and +0.1% 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.
