Iowa Corn 97% Planted as of May 31, 2026
Iowa's corn crop was 97% planted for the week ending May 31, 2026
What changed
USDA NASS reported Iowa corn at 97% planted for the week ending May 31, 2026. That puts the state's planting season very close to the finish line, with only a small fraction of acres left to go.
Why it matters
Getting corn in the ground by late May is a familiar benchmark for Iowa growers. At 97% planted, the vast majority of Iowa's corn acres are established and moving into early-season growth. The remaining 3% of unplanted acres could reflect late fields, replants, or prevent-plant situations — details worth watching as June progresses.
For corn across the state, attention now shifts from planting pace to stand establishment and early crop condition. How the crop emerges and responds to June weather will start to shape yield expectations for the 2026 season.
What to watch next
- First crop condition ratings: USDA typically begins publishing weekly good-to-excellent ratings for corn in early June. Those numbers will give a first read on how the planted crop is coming along.
- June weather patterns: Rainfall and temperatures over the next few weeks could affect emergence and early growth, especially on later-planted acres.
- Final planted acreage: USDA's June Acreage report (usually released at the end of June) will confirm total planted corn acres for Iowa and the rest of the Corn Belt.
