Iowa Corn Planting Reaches 42% as of May 3, 2026

What changed

USDA's National Agricultural Statistics Service reported that Iowa corn planting reached 42 percent planted for the week ending May 3, 2026. This weekly progress number gives farmers and market watchers a clear read on how the season is shaping up across the state.

Why it matters

Iowa is consistently one of the largest corn-producing states in the country, so its planting pace is worth watching every spring. The 42 percent planted figure tells us where things stand at this point in the season. How that number compares to the five-year average and last year's pace could affect expectations for the crop ahead. Weather in the coming weeks — particularly rainfall and soil temperatures — may influence how quickly the remaining acres get planted.
