Cost per pound of nitrogen
| Product | N content | Price per ton | Cost per lb of N |
|---|---|---|---|
| Anhydrous Ammonia | 82% | $908 | $0.55 |
| Urea (46-0-0) | 46% | $722 | $0.78 |
| Liquid Nitrogen (28-0-0) | 28% | $507 | $0.91 |
| Liquid Nitrogen (32-0-0) | 32% | $525 | $0.82 |
Cost per lb of N = price per ton ÷ (2,000 lb × nitrogen content). Compare products on this basis, then add application cost.

Common Fertilizers Explained
| Product | Analysis (N-P-K) | Main use |
|---|---|---|
| Anhydrous ammonia | 82-0-0 | Cheapest N per pound; injected as a gas, needs special equipment |
| Urea | 46-0-0 | Dry nitrogen; easy to spread, can lose N if left on the surface |
| UAN (liquid nitrogen) | 28-0-0 or 32-0-0 | Sprayed or dribbled; flexible timing |
| DAP | 18-46-0 | Phosphorus plus some nitrogen |
| MAP | 11-52-0 | Phosphorus, slightly more concentrated than DAP |
| Potash | 0-0-60 to 0-0-62 | Potassium |
Why Is Fertilizer So Expensive?
- Natural gas: it is the main raw material for ammonia, so nitrogen prices follow gas prices.
- Global trade: much of the world’s potash and phosphate comes from a few countries, so sanctions, tariffs and export limits move prices.
- Crop prices: when corn prices are high, farmers apply more fertilizer and dealers can charge more.
- Season: prices often rise into spring planting and fall application.

FAQ
How much does fertilizer cost per ton?
See the price cards at the top of this page for the latest USDA averages from Illinois dealers. Prices elsewhere differ with freight and local competition.
Which nitrogen fertilizer is cheapest?
Compare cost per pound of nitrogen, not price per ton. Anhydrous ammonia usually has the lowest cost per lb of N, but it needs application equipment. Our table works out the cost per lb of N for each product.
How often are fertilizer prices updated?
The USDA Illinois Production Cost Report comes out every two weeks. We check for a new report every weekday evening.
