Andy Jung of the Mosaic fertilizer group is watching the global grain market with growing alarm as 60 percent of Middle Eastern urea output vanishes. The closure of the Strait of Hormuz has stranded massive cargoes of nitrogen-based fertilizers, cutting off 45 percent of the global trade for a product that must be applied every season to ensure crop yields. From the fields of Brazil to the wheat belts of Europe, the lack of urea is threatening to turn a logistical bottleneck into a global food crisis. In rural farming communities, the smell of damp soil is now accompanied by the stench of soaring costs that the average producer cannot absorb.

In the end, some growers may just "roll the dice" and reduce fertiliser applications, putting yields at risk, said Andy Jung of the U.S. fertiliser group Mosaic. This gamble is forced by a maritime blockade that has allowed only 11 fertilizer-laden ships to transit the waterway since the conflict began in February. The result is a 'fertilizer squeeze' that has pushed farmer affordability to a four-year low. In the Global South, where small-scale farmers operate on razor-thin margins, the absence of nitrogen means the difference between a harvest and a humanitarian catastrophe.

European agriculture ministers are reportedly calling for strategies to safeguard the supply of fertilisers and to mitigate the impact of high energy prices. However, the structural reality is that the global food supply remains a captive of imperial choke points. As urea prices spike, the cost of staple crops remains too low for farmers to justify the expense, leading to a planned reduction in planting. This is not a market fluctuation but the dawn of 'Engineered Thirst' and hunger, where the energy needs of the North permanently displace the caloric needs of the South.
