OMAHA (DTN) -- All retail fertilizer prices moved higher compared to last month, according to retailers tracked by DTN in the second week of February 2026.

Seven of the eight major fertilizers are slightly higher compared to last month. DTN designates a significant move as anything 5% or more.

The one fertilizer with a substantial price increase was again urea. The nitrogen fertilizer was 5% higher compared to last month with an average price of $601/ton.

Urea was back above the $600/ton level for the first time since the first week of October 2025. That week the price was $601/ton.

The remaining seven slightly more expensive fertilizers were DAP with an average price of $851/ton, MAP $879/ton, potash $487/ton, 10-34-0 $665/ton, anhydrous $861/ton, UAN28 $411/ton and UAN32 $465/ton.

On a price per pound of nitrogen basis, the average urea price was $0.65/lb.N, anhydrous $0.52/lb.N, UAN28 $0.73/lb.N and UAN32 $0.73/lb.N.

Iran announced on Tuesday the temporary closure of the Strait of Hormuz for live fire military drills, according to the Associate Press. The U.S. and Iran held another round of indirect talks in Geneva on the same day over its disputed nuclear program.

It was the first time Iran has announced the closure of the key international waterway since the U.S. began threatening Iran and rushing military assets to the region. It marks a further escalation in a weekslong standoff that could ignite another war in the Middle East.

Iran's state media announced it had fired live missiles toward the Strait and would close it for several hours for "safety and maritime concerns."

This is not good for global fertilizer prices as the spring application season draws near for North America.

Approximately a third of the world's traded fertilizers pass through the Strait. Longer term closure could cause nutrient prices to rise rapidly, according to fertilizer analysts.

Nitrogen fertilizers, especially urea, would bear the brunt of this closure. Rabobank reports 45% of all urea exports come from this region. Other nutrients that would also be affected include MAP, DAP and ammonia.

All eight fertilizers are now higher in price compared to one year earlier.

10-34-0 is 4% higher, MAP is 9% more expensive, potash is 10% higher, urea is 12% more expensive, DAP is 13% higher, anhydrous is 15% more expensive, UAN32 is 18% higher and UAN28 is 20% more expensive looking back to last year.

DTN gathers fertilizer price bids from agriculture retailers each week to compile the DTN Fertilizer Index. DTN first began reporting data in November 2008.

Two state corn grower associations have sent letters to U.S. Attorney General Pam Bondi to explain what the Justice Department is doing to pursue possible antitrust action in the fertilizer industry, according to a DTN/PF article. You can read about here: https://www.dtnpf.com/….
