Fertilizer retailers reported falling prices heading into August, with UAN32 (32% nitrogen solution) posting the largest decline among major products tracked in DTN Progressive Farmer's retail fertilizer price survey.

The drop in UAN32 marks the most significant movement in a broader slide across the fertilizer complex. DTN's weekly survey, which collects prices from an average of roughly 250 retail locations across the Corn Belt and other production regions, has tracked a softening price environment for several weeks, and the August approach brought the declines into sharper focus.

For corn and wheat growers, the movement in UAN32 matters directly. Liquid nitrogen is a staple sidedress and topdress input in the Corn Belt, and falling retail prices trim one of the largest variable-cost line items in a corn budget at a time when margins remain tight. Any sustained decline in nitrogen prices also feeds into fall application decisions, since growers weighing anhydrous ammonia against liquid UAN formulations typically compare cost per unit of nitrogen rather than price per ton or per gallon.

DTN's price series has served as a benchmark for retail fertilizer moves for more than a decade, aggregating quoted prices from retailers and reporting averages across the major nutrients: urea, UAN32 and UAN28, anhydrous, liquid and dry phosphate products, potash, and sulfate-based products. Weekly moves in the series reflect what growers can actually expect to pay at the retail counter, distinct from wholesale benchmark prices at the wholesale hubs, which often lead retail quotes by several weeks.

The timing of the declines lands as growers finalize input budgets for the 2026 cropping season. Lower fertilizer costs entering late summer would ease one pressure point on farm margins, though the full effect depends on whether retailers pass the declines through quickly and whether nitrogen prices hold through the fall application window, when demand typically picks up.

DTN's next survey updates will show whether the UAN32-led decline extends across the nutrient complex or proves a temporary dip ahead of fall demand.
