OMAHA (DTN) -- Average retail prices for all eight major fertilizers tracked by DTN continued to be higher than last month during the last week of March 2025. However, the price of only one fertilizer saw a significant move, which DTN designates as anything 5% or more.

UAN32 was 6% higher compared to last month. The nitrogen fertilizer's average price was $423 per ton, up $26 per ton from $397 during the last week for February.

The remaining seven fertilizers had just slightly higher prices. DAP had an average price of $768 per ton, MAP $819/ton, potash $462/ton, urea $565/ton, 10-34-0 $650/ton, anhydrous $770/ton and UAN28 $360/ton.

On a price per pound of nitrogen basis, the average urea price was $0.61/lb.N, anhydrous $0.47/lb.N, UAN28 $0.64/lb.N and UAN32 $0.66/lb.N.

There has been much talk of tariffs affecting the price of fertilizer. Specifically, the price of potash, as the U.S. gets most of its supply from our northern neighbor, Canada.

So, I do find it interesting that the only fertilizer in our data with a significantly lower price than last year is potash. The price of the nutrient is 10% lower than one year ago, according to DTN data.

I am not a fertilizer analyst, but from talking to them, there are some logical explanations why potash prices haven't moved higher in recent months. While it is difficult to keep up with all of the latest developments, it appears Canadian potash could be exempt from the tariffs. Of course, this situation could change quickly.

In addition, many farmers already applied potash last fall and this spring for the 2025 growing season. The potash already delivered to retailers is not going to be affected by these various trade issues.

This is obviously good news for farmers already facing a 2025 growing season in which margins will be tight and profitability will be difficult. However, a lingering trade dispute into the second half of 2025 could push potash prices higher for the 2026 growing season.

Three fertilizers are now higher in price compared to one year earlier. UAN28 is 1% higher, 10-34-0 is 3% more expensive and UAN32 is 5% higher looking back to last year.

The remaining five fertilizers are lower. Both DAP and MAP are 1% less expensive, urea is 2% lower, anhydrous is 3% 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.

A global fertilizer affordability price index has dropped to its lowest level in two-and-a-half years, according to Argus Media. You can read about it here: https://www.dtnpf.com/….
