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

Two fertilizers had a sizable price increase from last month, which DTN designates as anything 5% or more. The average retail price of UAN32 was 9% higher compared to last month at $448 per ton. And UAN28 was 7% more expensive than last month with an average retail price of $380 per ton.

The remaining six fertilizers had slightly higher prices. DAP had an average price of $781 per ton, MAP $822/ton, potash $467/ton, urea $577/ton, 10-34-0 $655/ton and anhydrous $781/ton.

On a price per pound of nitrogen basis, the average urea price was $0.63/lb.N, anhydrous $0.48/lb.N, UAN28 $0.68/lb.N and UAN32 $0.70/lb.N.

University of Minnesota Extension nutrient management specialist Dan Kaiser, in a recent post, took a closer look at what happens to phosphorus fertilizer when it is applied to soil. Farmers should consider a few things when applying phosphorus, according to Kaiser.

Phosphorus utilization will never be 100% the first year after application, he wrote. Closer to 65% of what you apply will be taken up by the plant in the first year, according to the report.

Will phosphorus be lost through leaching or runoff? That depends on several factors, Kaiser wrote, but the potential for P loss is fairly low. Some researchers refer to P retention rather than fixation.

"Just because you do not see it does not mean it is not there," Kaiser said in the report.

Four fertilizers are now higher in price compared to one year earlier. DAP is 1% higher, 10-34-0 is 2% more expensive, UAN28 is 4% higher and UAN32 is 7% higher looking back to last year.

The remaining four fertilizers are lower. Both MAP and urea are 1% less expensive, anhydrous is 2% lower and potash is 9% 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.
