Michigan State University researchers, publishing in Nature Communications on March 5, found that Midwest summer daily minimum temperatures have risen while maximum temperatures have fallen, so warming may not raise crop water demand. They recommend soil management adaptation rather than irrigation for Midwest corn farmers.
Findings that irrigation expansion may be unnecessary reduce expected long-run cost pressures on Midwest corn and soybean production, a minor bearish consideration for prices.
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.
