A central Iowa farmer reports late-August heat and dryness shrinking soybeans and browning corn, and has cut his corn yield expectation to 160-170 bu/acre from 180-190. He expects low-50s bushel soybeans.
Farm-level yield cuts in Iowa, the largest corn state, reinforce the late-season yield risk in corn and soybeans. This supports feed grain prices if the trend spreads beyond local fields.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
