OMAHA (DTN) -- Average retail prices for all eight of the major fertilizers continued to be higher during the third week of March 2025, according to sellers surveyed by DTN.

Only one fertilizer had a substantial price increase, which DTN designates as anything 5% or more. The average retail price of UAN32 was 5% higher compared to last month at $412 per ton.

Prices for the remaining seven fertilizers were up just slightly from February. DAP had an average price of $766 per ton, MAP $810/ton, potash $454/ton, urea $556/ton, 10-34-0 $649/ton, anhydrous $761/ton and UAN28 $356/ton.

On a price per pound of nitrogen basis, the average urea price was $0.60/lb.N, anhydrous $0.46/lb.N, UAN28 $0.64/lb.N and UAN32 $0.64/lb.N.

A global fertilizer affordability price index has dropped to its lowest level in two-and-a-half years, according to an Argus Media report (https://www.argusmedia.com/…). Nutrient affordability fell to 0.82 points in March, the lowest level since November 2022, Argus data shows.

The affordability index is comprised of fertilizer and crop indexes. The index has dropped due to higher fertilizer prices for both phosphorus and potash fertilizers and lower crop (corn, wheat, rice, soybeans) prices due to global trade tensions.

"There is a risk that declining grain prices will weigh on demand for crop inputs," the report said.

Phosphate prices were supported by competing demand for limited supply. Potash prices have also been higher this year, also driven higher by a tighter supply, according to the report.

Two fertilizers are now higher in price compared to one year earlier. UAN32 is 2% higher, while 10-34-0 is 3% more expensive looking back to last year.

The remaining six fertilizers are lower. UAN28 is 1% less expensive, both DAP and MAP are 2% lower, urea is 3% lower, anhydrous is 4% less expensive and potash is 10% lower compared 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.
