Some Farmers Won't Get All Their Fertilizer for Planting

Why It Matters

A fertilizer shortfall threatens U.S. corn output, driving higher food prices and prompting a strategic shift in crop planting decisions.

Key Takeaways

• Strait of Hormuz closure threatens fertilizer deliveries to U.S. corn belt
• Up to 50% of global urea passes through the strait
• One‑third of U.S. farmers may face fertilizer shortages this planting
• Forward contracts may not guarantee supply or honored prices
• Diesel, seed, and herbicide supplies also constrained by geopolitical tensions

Summary

Farmers across the U.S. corn belt are confronting an unexpected supply shock as the military conflict between Iran and its adversaries has forced the closure of the Strait of Hormuz, a chokepoint that handles a sizable share of global fertilizer shipments. The disruption threatens to leave many growers without the urea and other nutrients they booked for spring planting.

Analysts estimate that roughly 25% of all fertilizer and up to half of the world’s urea traverse the strait. With shipments stalled, the odds that this year’s final spring fertilizer fill will arrive on time have dropped sharply. Industry sources suggest about one‑third of U.S. producers could feel a shortfall, even those who prepaid or forward‑contracted their needs.

“Some boats already in transit may be rerouted, and co‑ops might not honor contracted prices,” co‑host Michelle Rook warned. She added that growers could be forced to pivot to soybeans or accept lower corn yields, while the USDA’s response to the looming deficit remains uncertain.

The supply crunch could depress corn yields, reshape planting decisions, and push input costs higher, feeding volatility into commodity markets and ultimately raising food prices for consumers.
