OMAHA (DTN) -- Retail fertilizer prices shifted mostly lower in the first full week of September 2026.

For the third week in a row, six fertilizers were lower compared to last month, while the remaining two were slightly higher. DTN designates a significant move as anything 5% or more.

Unlike the previous week, none of the eight fertilizers had a significant move in either direction.

Six fertilizers were slightly lower compared to a month ago. Potash had an average price of $494/ton, urea $658/ton, 10-34-0 $717/ton, anhydrous $938/ton, UAN28 $430/ton and UAN32 $457/ton.

The remaining two nutrients were just slightly more expensive looking back a month. DAP had an average price of $923/ton and MAP $962/ton.

On a price per pound of nitrogen basis, the average urea price was $0.72/lb.N, anhydrous $0.57/lb.N, UAN28 $0.77/lb.N and UAN32 $0.71/lb.N.

At a meeting in Iowa last week, USDA Deputy Agriculture Secretary Stephen Vaden told more than 170 farmers from 13 states that the Trump administration is focused on increasing fertilizer supplies, while federal agencies also need farmers' help to build a case against the fertilizer industry over alleged anticompetitive practices (https://www.dtnpf.com/…).

The Iowa Corn Growers Association said farmers gathered in Iowa on Friday for a hearing with Vaden to discuss fertilizer prices and market competition. Farm groups have increased their efforts to raise concerns about high fertilizer prices and industry concentration.

"American farmers are being bled dry by fertilizer prices that have continued to climb, generating over $20 billion in profits for fertilizer shareholders within the past five years, while the American farmer has seen the price of fertilizer double, even tripling at times, since 2020," the Iowa Corn Growers stated.

At the meeting, corn growers continued to press their case that the federal government needs to address market consolidation in the fertilizer industry. Corn farmers held a similar event last May in Texas with the chairman of the Federal Trade Commission, which has announced an investigation into the fertilizer industry.

"We have continued to reiterate that as farmers, we cannot face big fertilizer alone, but that doesn't mean that we will be quiet and continue to be taken advantage of," Iowa Corn Growers Association President Steve Kuiper said.

Seven of the eight fertilizers are now higher in price compared to one year ago.

Potash is 1% higher, both urea and UAN28 are 4% more expensive, MAP is 5% higher, DAP is 7% more expensive, 10-34-0 is 8% more expensive and anhydrous is 22% higher looking back to last year.

UAN32 is the lone exception, running 5% lower than a year earlier.

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

Higher fertilizer prices could be here to stay, according to a recent report from CoBank. The report said lasting effects from the conflict in the Middle East, combined with tight supplies, could create higher prices and sourcing issues with nutrients in 2027 and beyond.
