UAN28 has led fertilizer price declines for the fifth consecutive week in DTN Progressive Farmer's weekly retail fertilizer price tracking, extending a run that directly eases one of growers' largest variable input costs heading into spring application.

The streak matters for nitrogen budgeting. UAN28 — a 28% nitrogen solution widely used in sidedress and spring pre-plant programs — functions as a key liquid nitrogen benchmark. Five straight weekly declines signal a sustained easing in the nitrogen complex rather than a one-week correction, giving crop producers room to re-quote nitrogen needs instead of locking in at earlier peaks.

What does the decline mean for farm margins?

For corn growers, nitrogen typically ranks among the heaviest per-acre input line items, alongside seed and crop protection. A sustained slide in UAN28 lowers the cash cost of a sidedress program and can shift the economics of application timing — delaying purchases becomes a rational strategy while the weekly trend points down.

DTN's survey tracks retail fertilizer prices across major U.S. crop regions, and its weekly cadence makes it one of the most closely watched reference points for dealers, co-ops and growers timing purchases. A five-week decline in the leading category suggests dealers are passing falling wholesale nitrogen values through to the farm gate.

Whether the slide continues depends on natural gas costs, spring demand pull and exporter positioning — variables the survey's next weekly readings will test.
