Posted: 27 May 2026 05:30 AM, Views: 645Tags: nass
USDA NASS published their weekly crop progress update yesterday and estimated 94% of Iowa's corn crop now planted. The featured map presents the statewide estimates with a departures against a simple and linear interpolated ten year average valid 24 May. All of the major corn producing states are shown in good shape. The mostly dry weather this week will likely push Iowa's value to near 100% by next week as the spring planting season draws to a close.
