Winfield United agronomists report that most Illinois corn and soybeans have reached maturity, with harvest underway in the south and slowed in the north by cool August temperatures. Rain in some states is hampering harvest while late-planted double-crop soybeans may be delayed.
Harvest delays and late maturity are a mild supply-timing factor, with limited direct price implication beyond normal harvest-pace commentary.
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.
