Wet weather has left Midwest farmers behind on spring planting, with 49% of corn and 30% of soybeans planted in the 18 surveyed states versus 78% and 58% a year earlier. Iowa farmer April Hemmes said she was two and a half to three weeks behind schedule.
Late planting cuts yields because crops accumulate less growing degree days before harvest.
Delayed planting threatens lower fall yields, which tightens corn and soybean supplies and supports feed prices. The size of the impact depends on whether planting catches up in May.
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, SOY moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
