US Fertilizer Prices Fall Sharply Amid Late Summer Retreat

US fertilizer prices have declined significantly since August 24th, with UAN28 and urea leading the market retreat. According to recent data from US agricultural retailers, UAN28 averaged $428 per ton, down 8% from a month earlier, while urea fell 5% to $655 per ton.

The decline in nitrogen prices is crucial for corn and other nutrient-intensive crop producers, as fertilizer remains a major component of operating expenses. Lower nitrogen quotations could improve purchasing opportunities as farms begin budgeting and securing inputs for the 2027 crop year.

Anhydrous ammonia dropped to $923 per ton, UAN32 stood at $458, 10-34-0 averaged $715, and potash slipped to $493. Phosphate products moved in the opposite direction, with DAP averaging $918 per ton and MAP $959.

While nitrogen costs have eased, the year-over-year picture still challenges farm margins. Anhydrous remained 21% above its late-August 2025 level, the largest annual increase among the eight fertilizers tracked. DAP and 10-34-0 were each about 7% higher, MAP 5%, urea 4%, and potash and UAN28 2%. UAN32 was the only product below year-earlier levels.
