Illinois fall anhydrous ammonia: a warm, late-drying fall with barge receipts in their usual range, autumn 2026
Adjacent · Operational, local · evidenced · Drought, 2026-10-29
“Our recommendation for fall ammonia application in Illinois is to wait until soil temperatures are below 50°F and use a nitrification inhibitor.” — source, 2026-11-04
The Department of Crop Sciences publishes the 50 °F rule that retailers and farmers use to open the fall ammonia window, and its Extension service ran a fall 2026 programme on it. Inferred: the rule converts a warm, dry fall into a shorter application window. The page is from 2024 and gives no 2026 readings.
