Wetter-than-expected fall weather has shifted Corn Belt focus to getting crops out before conditions worsen, particularly in Iowa. An Iowa State agronomist says early-season rain may have cut yield potential and fostered later disease problems.
Excess moisture that may have trimmed yields and raised disease risk can support feed grain prices if confirmed in harvest data, though the impact so far is modest.
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.
After 324 past neutral weather events, Soybeans moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% over 20.
