Key takeaways

When nitrogen fertilizer costs rise, farmers can reduce application rates, switch from nitrogen-intensive crops like corn to lower-nitrogen crops like soybeans, substitute among nitrogen products, or not plant in the worst case.
Urea demand is highly seasonal while plants run year-round, and producers tend to make and ship rather than store long-duration inventory.
Urea production depends on converting natural gas to ammonia and then converting ammonia into granular urea that is about 46% nitrogen.
Middle Eastern urea exports shift destinations seasonally, supplying Europe and the United States in the second quarter and more of India and Brazil in the second half of the year.
Morocco is a major low-cost phosphate producer and is expanding phosphate production.

When nitrogen fertilizer costs rise, farmers can reduce application rates, switch from nitrogen-intensive crops like corn to lower-nitrogen crops like soybeans, substitute among nitrogen products, or not plant in the worst case.
The urea-to-corn price ratio is near record levels and is treated as a key affordability metric for farmers.
Urea prices increased by roughly 25% over the past week amid the conflict-related shock.
U.S. farm margins are very thin, the input-versus-output price spread hit a record negative level in January, and Chapter 12 farm bankruptcies are rising in 2025.
The market is calling for reduced U.S. nitrogen application rates and a preliminary view is that U.S. corn yields could fall from about 186 to about 182 bushels per acre, with food-price effects transmitting over roughly one to two years from planting through processing and consumption.
Urea affordability for corn farmers is expected to set a new record as the urea-to-corn ratio rises beyond prior highs once prices settle.

Urea demand is highly seasonal while plants run year-round, and producers tend to make and ship rather than store long-duration inventory.
There is no meaningful strategic reserve of urea comparable to oil.
The conflict-related fertilizer disruption is occurring during Northern Hemisphere second-quarter planting season, a peak period for fertilizer application.
If farmers miss the narrow pre-plant and early-emergence nitrogen application window, they generally cannot make it up later and must absorb a yield penalty.
Even if the Strait of Hormuz reopened, fertilizer exports from the Middle East would likely take at least two to three weeks to resume meaningfully due to restart time, vessel logistics, and probable oil-priority shipping.

Urea production depends on converting natural gas to ammonia and then converting ammonia into granular urea that is about 46% nitrogen.
When China is out of the export market, nitrogen prices rise to the next level of production costs, which in 2022 meant restarting higher-cost European production amid very high natural gas prices.
Nitrogen fertilizer plants are often co-located with low-cost natural gas because natural gas is expensive to ship while urea is cheaper to transport as a bulk granular commodity.
At $60 per MMBtu European natural gas, ammonia feedstock costs alone exceed roughly $2,100 per ton of ammonia when using about 34–36 MMBtu per ton.

Middle Eastern urea exports shift destinations seasonally, supplying Europe and the United States in the second quarter and more of India and Brazil in the second half of the year.
The 2022 fertilizer spike was driven first by China’s 2021 export ban removing a marginal supplier for urea/phosphate and then by Russia’s invasion of Ukraine increasing uncertainty over sourcing from a major low-cost exporter.
Countries along the Persian Gulf account for about 45% of the world’s tradable urea supply and about 20% of ammonia supply.
With Russia constrained by Western sanctions and China imposing an export ban on urea, alternatives to replace Middle East supply are limited to places like Egypt or the United States.

Morocco is a major low-cost phosphate producer and is expanding phosphate production.

What is the measured extent of fertilizer production and export disruption in Persian Gulf countries (plant outages, port closures, loading delays) during the conflict window?
How much urea inventory is held across major importing regions (U.S., Europe, India, Brazil) at the moment of disruption, and what is the weeks-of-cover relative to peak seasonal demand?
Are China’s urea export restrictions and Russia-related constraints currently binding at the levels implied, and what is the effective tradable supply available outside the Middle East?
What is the current urea-to-corn ratio computed from observable weekly assessments and nearby corn futures, and does it exceed prior peak levels after prices stabilize?
What are actual U.S. nitrogen application rates this season versus baseline, and are farmers shifting acreage between corn and soybeans at the margins described?

A spike in the urea to corn affordability ratio could transmit to agricultural output via reduced nitrogen application, corn to soybean acreage shifts, or non planting, with downstream impacts appearing after planting and then at harvest and processing stages.
Just in time seasonality and limited inventory buffering imply that short urea export disruptions can have outsized effects if they coincide with early season application windows, especially given multi week restart and logistics lag.
Natural gas cost moves can reset nitrogen cost curves through the gas to ammonia to urea chain, potentially forcing prices up to the next cost tier when tradable supply is constrained by export restrictions and sanctions.

Measured evidence of Persian Gulf urea production or export disruption during the conflict window, such as plant outages, port closures, or loading delays, persisting beyond headline timing.
Inventory and weeks of cover data in the United States, Europe, India, and Brazil showing low buffers into peak seasonal demand, alongside observable rerouting of Middle East exports by quarter.
Observable urea to corn ratio exceeding prior peaks after prices stabilize, plus reported reductions in U.S. nitrogen application rates or marginal corn to soybean acreage shifts.

No material Persian Gulf export disruption, with shipment flows and loading times remaining normal through the relevant seasonal window.
Importing region inventories show ample weeks of cover through peak application periods, reducing sensitivity to short disruptions and restart lags.
Affordability ratio normalizes while observed application rates and acreage choices stay near baseline, indicating limited real economy transmission from fertilizer prices.
