OMAHA (DTN) -- Average retail fertilizer prices were mixed during the first week of November 2026, according to sellers surveyed by DTN.

Five of the eight major fertilizers were slightly more expensive compared to last month, while the remaining three were slightly less expensive. No fertilizer saw a significant price move, which DTN designates as a change of 5% or more.

The five fertilizers that were slightly more expensive were DAP, with an average price of $950 per ton, MAP at $991/ton, potash at $504/ton, 10-34-0 at $704/ton and anhydrous at $1,003/ton.

Prices for the remaining three nutrients were down slightly from last month. Urea had an average price of $662/ton, UAN28 $428/ton and UAN32 $484/ton.

On a price-per-pound-of-nitrogen basis, urea averaged $0.72/lb.N, anhydrous $0.61/lb.N, UAN28 $0.76/lb.N and UAN32 $0.76/lb.N.

All eight fertilizers are now more expensive than a year ago.

Compared to a year ago, DAP, potash and UAN28 are 3% more expensive, UAN32 is 4% higher, 10-34-0 is 6% higher, MAP is 7% higher, urea is 11% higher and anhydrous is 17% higher.

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

FERTILIZER NEWS

The Iowa Department of Natural Resources is investigating a liquid fertilizer spill near Fort Madison in Lee County. On Oct. 26, the DNR Field Office in Washington was notified of the release of liquid fertilizer (UAN 32%) from an on-site containment tank at the Merschman Fertilizer facility in Fort Madison.

One tank developed a leak in early October, which required the staff to pump the product into an alternate tank. Both tanks sit inside a secondary containment berm that is poly-lined with 6 to 8 inches of gravel.

Facility staff activated a sump pump to remove liquid from the containment area following recent rains. An unknown amount of product and rainwater mixture was pumped over the berm into a drainage ditch south of the property. This ditch connects to an unnamed tributary that empties into the Mississippi River.

Cleanup operations have begun. Facility staff are pumping the remaining product and rainwater mixture into an alternate on-site storage tank, and temporary dams have been placed in multiple places in the tributary.

No dead fish have been observed at this time. Water samples have been collected, and the investigation is ongoing. Residents are asked to avoid the area currently.
