The Iran war has resulted in a shortage of fertiliser imports from the Middle East, a major fertiliser production hub in Qatar, and disruptions to global supply routes. The Strait of Hormuz, the source of much of the global fertiliser trade, has seen significant disruption as it navigates through the conflict. The Middle East is a major hub for nitrogen-based fertiliser manufacturing, with supplies halted from the world's largest facility in Qatar and sulphur and ammonia also curbed. However, farmers can cut back on other core nutrients without immediate yield losses. At least 2 million metric tons of urea production, equivalent to around 3% of annual seaborne trade, have been lost since the conflict began. The immediate impact on global food supplies may be limited, but the risk of further disruption is expected to occur during autumn planting when European farmers may cut overall grain area.
