The conflict in Iran, which began on February 28, 2026, has blocked the Strait of Hormuz, disrupting global fertilizer shipments and driving up costs for American farmers already burdened by economic pressures.
Disruption from Strait of Hormuz Blockade
- The war has effectively blocked the Strait of Hormuz, a critical chokepoint through which one-third of the world's fertilizer passes.
- This blockade occurs just as US farmers prepare for the spring planting season, starting as early as March.
Soaring Fertilizer Costs
- Nitrogen, a key fertilizer component, is seeing rapid price increases, with suppliers hesitant to provide quotes.
- Imported urea, a nitrogen-based fertilizer, has risen by nearly a third since the US and Israel attacked Iran, according to FactSet.
- Even US-made fertilizer is becoming more expensive due to rising natural gas costs.
