Iran war has US farmers worried about the cost and availability of fertilizer - AP News

US farmers are concerned that escalating tensions with Iran could disrupt fertilizer supplies and drive up costs for a critical agricultural input. Iran is a major global producer of potash and ammonia-based fertilizers, and any military conflict or sanctions could restrict exports to American markets. Fertilizer prices have already experienced volatile swings in recent years due to geopolitical disruptions, and farmers depend on stable, affordable supplies to maintain crop yields and profit margins. A prolonged shortage would squeeze farm economics at a time when input costs remain a significant pressure on agricultural operations. The concerns underscore how global supply chains for essential commodities leave US agriculture vulnerable to international crises beyond farmers' control.
