Iowa Corn 72% Emerged as of May 24, 2026

What changed

Iowa corn emergence hit 72% for the week ending May 24, 2026, according to USDA NASS Quick Stats. That's a sizable weekly gain of 26 percentage points from the 46% reported for the week ending May 17. A move that large in a single week signals that growing conditions across much of the state allowed rapid stand establishment.

Why it matters

Emergence pace is one of the earliest checkpoints for the Iowa corn crop each season. A strong week of emergence like this one suggests that soil temperatures and moisture were cooperating across a wide swath of Iowa's corn acres. For growers still watching their own fields come up, the statewide number provides a benchmark — if your stands are lagging well behind 72%, local conditions (cold pockets, crusting, saturated spots) may be worth a closer look.

What to watch next

• Next week's NASS update will show whether emergence continues to climb toward the 90%+ range or if weather slows the pace.
• Condition ratings typically begin appearing in NASS reports once emergence is far enough along — those first Good/Excellent percentages could arrive soon for Iowa corn.
• Local stand counts in your own fields remain the most relevant number for your operation. The statewide figure is a useful reference point, not a substitute.
