| Benchmark | Price | vs. 2025 |
|---|---|---|
| NOLA barge (national reference) | $640–$740/ton | +15–25% |
| Oklahoma co-op / distributor | $691–$799/ton | +23–33% |

Hold aggressive pre-buying until August China restriction decision. Spot may correct 10–15% if restrictions lift.
Oklahoma sources fertilizer primarily via rail and truck from Texas Gulf Coast producers; proximity to Enid-area nitrogen facilities provides modest pricing advantage.
| Driver | Impact |
|---|---|
| China phosphate export ban | China restricted phosphate exports through August 2026, removing ~30% of global trade volume — the single largest price driver. |
| Morocco and Saudi supply | Alternative suppliers (OCP, SABIC) run at capacity but cannot fully offset China volumes. |
| Ammonia input costs | DAP production requires ammonia; elevated natural gas costs raise the cost floor. |
| Spring demand surge | Concentrated spring application demand amplifies price spikes during March–May. |
