USDA's January 2022 report put 2021 North Dakota corn at 105 bu/acre versus 139 in 2020, and Minnesota at 178 versus 191. Soybean yields also fell in the Dakotas, with North Dakota at 25.5 bu/acre versus 34 in 2020.
Drought-cut yields in the northern Plains tightened regional supplies of corn and soybeans for feed users. The national crop was still large, so the effect on prices was limited.
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.
