Iran Conflict: How Food Can Prepare for Fertiliser Shortages

Why It Matters

Fertilizer price volatility threatens food security and profit margins for commodity producers, prompting a strategic shift toward low‑input, climate‑smart agriculture.

Key Takeaways

• Fertilizer prices rose 20‑45% during Strait closure.
• Maize, rice, wheat most vulnerable to input cost spikes.
• Legumes, millet, sorghum require less synthetic fertilizer.
• Agro‑ecological practices can reduce dependence on fossil‑fuel inputs.

Pulse Analysis

The temporary closure of the Strait of Hormuz exposed a thin spot in the global fertilizer supply chain. Over two weeks, the chokepoint that moves the majority of phosphate and nitrogen‑based fertilizers from the Persian Gulf to world markets stalled, pushing spot prices up 20‑45 percent. Those spikes immediately translated into higher production costs for staple grains such as wheat, rice and maize, tightening food‑price inflation in import‑dependent regions. Analysts now treat the Hormuz corridor as a strategic commodity artery, and any future disruption is being factored into risk models for agribusiness investors.

Faced with higher input costs, growers are revisiting crops that naturally fix nitrogen or thrive on modest fertilization. Legumes—including soy, beans, peas and lentils—draw atmospheric nitrogen, cutting synthetic fertilizer demand by up to 70 percent. Small‑holder farms in Africa and South Asia have long relied on millet and sorghum for their resilience to low‑input conditions. However, large‑scale commodity systems built around wheat, rice and maize face structural inertia: entrenched seed contracts, processing infrastructure and subsidy regimes make rapid crop switches costly and logistically complex.

Long‑term mitigation points toward agro‑ecological farming, which blends diversified rotations, cover crops, organic amendments and reduced tillage to rebuild soil fertility without fossil fuels. Policymakers can accelerate this transition by redirecting research grants, extending credit for low‑input technologies, and revising subsidy formulas that currently favor high‑chemical inputs. Private capital is also emerging for biostimulants and precision‑agriculture tools that optimize nutrient use. As climate change intensifies and geopolitical tensions persist, building a fertilizer‑independent food system is becoming a competitive advantage rather than a niche experiment.
