Fall nitrogen application — usually in the form of anhydrous ammonia — is an important crop production practice across many northern Corn Belt states. The window to get the job done is tight. Reliable, agronomically designed equipment from Case IH helps ensure it gets done right.
Fall fertilizer applications are popular among farmers in colder northern regions. The timing offers several advantages,1 including:
- Reduced soil compaction compared with typically wetter spring conditions
- Spreads the workload, which can help keep planting season on track
- Ensures nitrogen is in place if conditions turn too wet for timely spring sidedress applications
[Tweet “Help keep fall-applied nitrogen in place. Via @Case_IH #BeReady “]To help keep fall-applied nitrogen in place and available for next year’s corn crop, apply anhydrous ammonia after the soil temperature (at a 4-inch depth) cools below 50 degrees and before soil freeze.2 Depending on when harvest wraps up, the window might be relatively wide. Yet even during an open fall, conditions can turn winterlike, seemingly overnight. That’s why it’s important to be field-ready when soil temps drop.
From heavy-duty construction to high clearance for even crop residue flow, Case IH offers rugged, dependable fertilizer application equipment for timely fall fertilizer applications. Talk with your Case IH dealer about the options best suited to your individual needs:
