Iran war: The fertiliser challenge India faces, and the possible way out

📌 Summary:

• Context: US-Israel vs Iran war and Strait of Hormuz closure (since February 28) triggered severe fertiliser import supply shock for India

• Price spike: IPL urea tender (April 4) received bids at $935/tonne (west coast) vs $508/tonne in RCF tender (February 18) — ~84% price spike in 2 months

• DAP (di-ammonium phosphate): ~$865/tonne vs pre-war $720 and last year's $680

• Mechanisms of impact: (1) Strait of Hormuz closure blocks Middle East fertiliser exports — Iran, Oman, Qatar are major urea and ammonia suppliers (2) Global supply re-routes via longer routes → freight costs surge (3) Crude oil-linked production costs rise — urea synthesis uses natural gas (priced on crude benchmarks) (4) Potash supply also disrupted from Central Asian routes

• India's fertiliser import dependency: world's 2nd-largest urea consumer; imports 25-30% of urea; highly import-dependent on DAP (phosphatic fertilisers)

• Seasonal risk: India may manage kharif (summer) season; rabi (winter) is the critical vulnerability — DAP demand peaks for wheat and rabi oilseeds

• Alternative strategies: (1) Nano-urea (IFFCO) reduces conventional urea requirement; (2) Zinc-coated urea enhances efficiency; (3) Biostimulants (microbes, humic acids, seaweed extracts) improve nutrient use efficiency without adding inputs

• Broader implication: fertiliser price rise feeds through to food production costs, threatening food inflation

🎯 UPSC Relevance: GS3 – Indian Economy: Agriculture, Food Security; GS2 – IR: Impact of West Asia conflict on India; Critical for Mains 2026; GS3 – Disaster Management: supply chain shocks

📝 Prelims Facts:

• Strait of Hormuz closure: February 28, 2026

• IPL: Indian Potash Limited — govt import agency

• IFFCO Nano Urea: liquid formulation reducing conventional urea use by ~50%

• DAP: di-ammonium phosphate — key rabi crop fertiliser

🔑 Key Term: Biostimulants – microbe-based, humic acid, or seaweed-derived products that improve plants' internal nutrient use efficiency without supplying nutrients directly; can reduce fertiliser input requirements by 10-20%
