US fertiliser markets extended their upward run in mid-September 2026, with six of eight benchmark products posting week-on-week gains, according to weekly retail price tracking. Seven of the eight fertilisers now trade above where they stood at the same point in 2025.
Anhydrous ammonia remains the standout, sitting roughly 22% higher than a year ago, reflecting tighter supply and firm demand heading into the autumn application season. The broad-based increase across nitrogen, phosphate and potash products points to sustained cost pressure for growers and buyers rather than an isolated move in a single nutrient.
For trading desks and input buyers, the pattern suggests limited near-term relief on procurement costs, with replacement values likely to keep pace with or exceed last year's benchmarks into the key autumn and spring buying windows.
