Iowa Soybeans 95% Planted as of May 31, 2026

What changed

USDA NASS reported Iowa soybeans at 95% planted for the week ending May 31, 2026. At that level, the vast majority of Iowa's soybean acres are in the ground, with only a small fraction of fields still to finish.

Why it matters

Hitting 95% planted by the end of May puts Iowa in solid shape for the soybean crop year. Remaining unplanted acres are a small slice — but for those fields still waiting, calendar pressure picks up in June. Planting date can influence yield potential, so the timing of that last 5% is still worth paying attention to.

What to watch next

• Emergence numbers: The next round of USDA crop progress reports will show how quickly planted acres are emerging. Earlier reports had Iowa soybeans at 57% emerged as of May 24 — that figure could move fast with warmer weather.
• Final planting push: Keep an eye on whether the remaining 5% gets wrapped up in the first week of June, and whether any weather delays affect those last acres.
• Early-season crop condition: Once planting is complete, USDA typically begins reporting crop condition ratings, which will give a first read on how the 2026 Iowa soybean crop is starting out.
