How Recent Fertilizer Price Increases Affect Your Per-Acre Costs

Recent increases in fertilizer prices, especially for nitrogen-based inputs, are raising production costs. This article summarizes recent price trends in our region and provides a simple worksheet for you to calculate your own cost of production.

1. Increase in recent fertilizer prices

March 30 vs. Mid-February

  • Urea: +40%
  • Liquid nitrogen 32%: +29%
  • DAP (18-46-0): +5%
  • MAP (11-52-0): +5%
  • Potash: +3%

March 2026 vs. March 2025

  • Urea: +38%
  • Liquid nitrogen 32%: +53%
  • DAP (18-46-0): +4%
  • MAP (11-52-0): +8%
  • Potash: +4%

2. Translating fertilizer prices into production costs

Fertilizer prices are typically reported in dollars per ton, but farmers apply fertilizer in pounds per acre. To translate market prices into on-farm costs, the price per ton is first converted to a price per pound by dividing by 2,000 (the number of pounds in a ton). This per-pound price is then multiplied by the application rate (in pounds per acre) to calculate fertilizer cost per acre.

  • Fertilizer cost per acre = fertilizer price per ton / 2000 * application rate.
