Fertilizer prices in the United States rose sharply in April 2026, according to data compiled by the newsroom, with all major nutrients increasing month-over-month-an important development as it raises input costs, pressures farm margins, and influences planting decisions ahead of the growing season.

The latest data show a broad-based rally across both dry and liquid fertilizers, signaling continued volatility in agricultural input markets. Six of the eight major fertilizers recorded significant price increases of 5% or more, highlighting persistent supply constraints and strong seasonal demand.

10-34-0 leads the surge in fertilizer markets

The starter fertilizer 10-34-0 posted the largest monthly gain, rising 17% to an average of $ 722 per ton, making it the biggest driver of the current price rally. This increase is particularly relevant for corn producers, who rely heavily on starter fertilizers to optimize early-season yields.

Other nitrogen-based fertilizers also saw notable increases. UAN28 climbed 9% to $526 per ton, while anhydrous ammonia rose 8% to $1,116 per ton, reflecting tight supply conditions and elevated energy costs.

Nitrogen and phosphate fertilizers push higher

UAN32 increased 7% to $ 595 per ton, while both DAP and urea registered 5% gains, reaching $ 901 and $ 866 per ton, respectively. These increases are critical for U.S. farmers managing nutrient applications under rising cost pressure.

Meanwhile, MAP and potash posted more modest increases, with average prices at $ 939 and $ 492 per ton. Despite smaller monthly changes, both nutrients remain significantly higher compared to last year.

Policy response aims to boost supply

In response to rising fertilizer costs, the U.S. government has introduced measures aimed at expanding domestic production and easing supply bottlenecks. Officials project a potential 30% increase in domestic nitrogen capacity, a doubling of potash output, and a 200% expansion in phosphate production within the next two years.

Short-term actions have also been implemented to stabilize the supply chain, including regulatory flexibility to improve fertilizer transportation and temporary adjustments to import restrictions.

These policy moves are expected to play a key role in shaping the fertilizer market outlook and could influence future provisions in the farm bill, particularly around input cost management and domestic production incentives.

Year-over-year increases highlight ongoing pressure

All eight major fertilizers are now more expensive than a year ago, with several posting double-digit gains. Urea prices have surged 50% year-over-year, while anhydrous ammonia is up 43% and UAN28 has increased 38%.

These trends underscore the broader challenge facing U.S. agriculture: balancing higher commodity prices with rising input costs. For many producers, profitability will depend on efficient nutrient management, adoption of precision agriculture technologies, and strategic use of crop insurance.
