OMAHA (DTN) -- Higher fertilizer prices are here.

Average retail prices for all eight of the major fertilizers were higher than last month during the second week of March 2026, according to sellers surveyed by DTN. Half of the nutrients had a sizeable price increase, which DTN designates as anything 5% or more. Retail prices are rising due to the U.S.-Israel-led war with Iran.

The price of UAN28 saw the biggest jump, up 13% compared to last month. The liquid nitrogen fertilizer had an average price of $464 per ton.

The price of urea was 12% higher than last month at $674 per ton. Anhydrous was 7% more expensive compared to last month with an average price of $924/ton. The price of UAN32 was up 5% from last month at $489/ton.

Anhydrous was above the $900-per-ton level for the first time since the second week of May 2023. That week, the price was $910/ton.

Prices for the remaining four nutrients were slightly higher. DAP had an average price of $851/ton, MAP $889/ton, potash $488/ton and 10-34-0 $670/ton.

On a price per pound of nitrogen basis, the average urea price was $0.73/lb.N, anhydrous $0.56/lb.N, UAN28 $0.83/lb.N and UAN32 $0.76/lb.N.

Iran appears to be allowing some ships through the Strait of Hormuz, freeing a trickle of oil and maybe some nutrients, according to a Dow Jones article.

Karachi, a crude-oil tanker flying under the Pakistan flag, sailed through the strait on Sunday while broadcasting its location, becoming the first non-Iranian vessel to have done so since the U.S.-Israel military conflict with Iran began, according to ship-tracker MarineTraffic.

The vessel, a midsized tanker carrying Abu Dhabi crude, departed from Das Island. The island is a major hub for offshore oil and gas processing and exports in the Persian Gulf 100 miles northwest of the United Arab Emirates mainland.

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

10-34-0 is 4% higher; potash is 9% more expensive MAP is 10% higher; DAP is 11% more expensive; urea is 14% higher; urea, anhydrous and UAN32 are all 23% higher and UAN28 is 31% higher 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.

The American Farm Bureau Federation (AFBF) said it is in communication with the White House and USDA to discuss ways to mitigate the effects of the halt of fertilizer shipments through the Strait of Hormuz and the possibility of additional aid payments have been discussed, according to Dow Jones.
