An agronomist in west central Iowa reports that roughly half or more of farmers are through harvest, with soybean harvest finished on many farms and corn underway. He describes corn yields as exceptionally good and calls it one of the best harvest seasons in recent years.

After 357 past bearish weather events, Corn moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.3%), and -0.5% 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.
