17-17-17 Fertilizer Price Per Ton: The Current Numbers

The most recent verified retail quote for 17-17-17 NPK blend, published by the USDA Agricultural Marketing Service for Alabama, was $746.55 per ton in September 2025, up from $734.15 per ton in April 2025 — a $12.40 increase over five months. That is the only region-specific 17-17-17 retail figure USDA AMS currently publishes; no equivalent Midwest, Great Plains, or broader Southeast quote exists in the public record as of this review, so treat Alabama as a directional benchmark rather than a national average, and get a written local quote before you budget against it. The USDA AMS Illinois Production Cost Report covers straight nitrogen, phosphate and potash products but does not list 17-17-17.

If you searched for “triple 17 fertilizer price” or “17 17 17 fertilizer price” expecting a single global number, here is the honest answer: no single global or national average for 17-17-17 is published on a regular schedule. What exists is a bi-weekly regional retail snapshot (the AMS report above) plus wholesale prices for the raw nutrients that go into any NPK blend — anhydrous ammonia, DAP, and potash — published monthly by University of Illinois farmdoc daily. Both are cited with figures below, and both tell you more than a single averaged price ever could, because they let you see which input is driving your cost up.

Calculator: Your 17-17-17 Cost Per Acre

Because the per-ton price only matters once you know how much you’re spreading, use the calculator below to convert a quoted ton price into a per-acre and total-field cost. Enter your own quote — don’t rely on the Alabama figure above if you’re buying elsewhere, since AMS does not publish a Midwest or Great Plains equivalent yet.

What 17-17-17 Fertilizer Is and Why the Ratio Matters

17-17-17 fertilizer is a granular compound blend containing 17% nitrogen (N), 17% phosphorus as P2O5 (P), and 17% potassium as K2O (K) by weight — a 1:1:1 ratio. It’s used across cereals, fruit, and vegetable operations in the US and elsewhere because it delivers all three primary macronutrients in one pass, without requiring a farmer to blend or stack separate straight fertilizers.

• ✔ Uniform Nutrient Delivery: One bag covers nitrogen, phosphorus, and potassium needs in equal measure — useful where a soil test shows no single nutrient is dramatically more deficient than the others.
• ⚡ Vegetative Growth: Nitrogen drives leaf and stem development.
• 🌱 Root Strength: Phosphorus supports root establishment and energy transfer.
• 💧 Water Regulation: Potassium regulates water retention and stress tolerance.
• 🍇 Crop Versatility: Works across cereals, fruit, and vegetable rotations without reformulation.

Buying 17-17-17 by the Bag, Including at Southern States

Many buyers searching for 17-17-17 fertilizer at Southern States want bagged product for pasture, hay, gardens or food plots. Southern States is a farmer-owned cooperative founded in 1923 (Southern States). When we searched its online store for “17-17-17” on 27 September 2026, no 17-17-17 product was listed, so the local store is the place to ask for price and stock.

The label arithmetic is the same wherever you buy:

To compare a bag price with a bulk ton price, multiply the price of a 50 lb bag by 40. To compare with straight products, divide the price by the pounds of nutrient you actually need. If a soil test calls only for nitrogen, paying for 340 lb of P2O5 and 340 lb of K2O in every ton is money spent on nutrients the field does not use.

Nitrogen, Phosphate and Potash: What’s Actually Inside the Price

A 17-17-17 ton price moves because the three commodities inside it move — and they don’t move together. Here is where each stood most recently, by source:

• Nitrogen (anhydrous ammonia, 82-0-0): $786 per ton in Illinois, August 2025 (USDA AMS), rising to $915.50 per ton by August 2026 (farmdoc daily) — a $129.50 increase.
• Nitrogen (urea, 46-0-0): $594 per ton, Illinois, August 2025 (USDA AMS).
• Phosphate (DAP, 18-46-0): $912.22 per ton wholesale, August 2026 (farmdoc daily) — this is the figure behind “phosphate fertilizer price cost per ton” searches; there is no separately published 2026 phosphate rock price in this brief, so DAP is the closest tracked proxy.
• Potash (0-0-60): approximately $500 per ton wholesale, August 2026 estimate (farmdoc daily).

Nationally, US farmers used 12.5 million tons of nitrogen fertilizer, 3.8 million tons of phosphate fertilizer, and 6.2 million tons of potash fertilizer in 2023, according to USDA NASS data compiled by USDA ERS. Those are the most recent finalized annual totals; 2024 and 2025 consumption figures had not been published as of this review.

For “nitrogen fertilizer price per ton” searches specifically: anhydrous ammonia and urea are the two forms USDA AMS and farmdoc daily track by name. Neither is the same product as 17-17-17 — they’re pure nitrogen carriers — but they set the floor under any blended product’s nitrogen component, so a spike in either shows up in your next 17-17-17 quote within one to two purchasing cycles.

Price Comparison Table: 17-17-17 vs. Its Raw Inputs

This table separates the two things people searching “17-17-17 fertilizer price per ton” actually need: the blended retail price, and the wholesale inputs that predict where it’s headed next.

Read this table as a diagnostic, not a shopping list: if your local 17-17-17 quote has jumped more than the ammonia and DAP lines above combined, ask your supplier what’s driving the difference — freight, a regional shortage, or margin, since none of those show up in the national wholesale numbers.

What Moves the 17-17-17 Fertilizer Price Per Ton

Five forces set the number you see quoted, in roughly this order of near-term impact:

1. Natural gas and energy costs:
   Anhydrous ammonia production runs on the Haber-Bosch process, which is natural-gas intensive. The $786-to-$915.50-per-ton move in Illinois ammonia between August 2025 and August 2026 (USDA AMS, farmdoc daily) tracks energy input costs more closely than any other single factor.
2. Raw material and mining supply:
   Phosphate rock and potash are mined commodities. Export restrictions or mine-level disruptions in producing countries tighten global supply and show up first in wholesale DAP and potash quotes, then filter into blended retail prices over subsequent purchasing cycles.
3. Logistics and regional distribution:
   USDA AMS publishes retail 17-17-17 prices for Alabama specifically because regional dealer networks, rail access, and barge routes create real price gaps between states — which is exactly why a single national average understates what any one farm actually pays.
4. Farm-level budgeting exposure:
   USDA projects corn fertilizer costs at $166 per acre for 2026 (farmdoc daily), which sets the planning baseline row crop operations use when comparing a straight-nitrogen program against a compound blend like 17-17-17.
5. Environmental and runoff regulation:
   Nutrient management rules in states bordering the Great Lakes, Chesapeake Bay, and Gulf Coast watersheds increasingly require documented application rates, which raises compliance cost without necessarily raising the ton price itself.

Runoff Rules and Sustainability Reporting

Nutrient runoff regulation is the policy layer sitting on top of every price number above. It doesn’t set the ton price directly, but it does set how much of a ton you’re allowed to apply, when, and how you have to document it.

• Nutrient Runoff Rules: States and watershed authorities across the US increasingly require documented nitrogen and phosphorus application rates near sensitive waterways, limiting over-application and protecting water bodies from eutrophication.
• Carbon Footprinting: Standards for tracking the full production-to-field carbon impact of fertilizer inputs are expanding — see Farmonaut’s carbon traceability tools for how operations are documenting this today.
• Precision Application Requirements: Some conservation program payments now condition eligibility on documented, site-specific application rates rather than flat per-acre averages.

Getting the Most Out of Every Ton You Buy

At $746.55 per ton (Alabama, September 2025, USDA AMS) or higher depending on your region, every pound of 17-17-17 that runs off a field instead of feeding the crop is a direct loss. The checklist below is what keeps that loss down regardless of what the price does next quarter.

Application Checklist for 17-17-17

• 🧪 Soil Test First: Confirm your field actually needs equal N, P, and K before buying a 1:1:1 blend — many fields don’t.
• 🕒 Match Timing to Growth Stage: Apply ahead of root and shoot development windows specific to your crop, not on a fixed calendar date.
• 💧 Manage Irrigation to Limit Leaching: Overwatering after application pushes nutrients past the root zone. See sustainable leaching-control practices for the underlying mechanics.
• 🛠️ Use Mapping Tools for Variable-Rate Application: A satellite-based farm management platform can flag zones needing more or less than a flat rate.
• 📑 Track Yield Response Season to Season: Use your own harvest data to adjust next year’s rate — published agronomic trial data specific to 17-17-17 blends by crop was not found in current USDA sources, so on-farm records are the most reliable input you have.

• ✔ Cost-Efficiency: Matching rate to soil test avoids paying $746.55+/ton for nutrients the field will not use.
• 📊 Data-Driven Decisions: Field-level monitoring turns a flat per-acre budget into a variable-rate plan.
• ⚠ Risk Reduction: Over-application at current price levels compounds financial loss with runoff liability.
• 🌍 Sustainability: Efficient use protects long-term soil structure and water quality.
• 🚜 Access: Platforms like Farmonaut put satellite-based nutrient insight within reach of operations of any size.

What Rising Input Costs Mean for Farm Budgets and Policy

• ⚖️ Affordability: A $746.55/ton retail price (Alabama, September 2025) directly affects margins on any operation applying 17-17-17 at scale.
• 👨‍🌾 Regional Access: USDA AMS’s Alabama-only 17-17-17 coverage means farmers elsewhere in the US should request written quotes rather than assume a national price applies to them.
• 📈 Budget Planning: USDA’s $166-per-acre projected 2026 corn fertilizer cost (farmdoc daily) is a useful benchmark for comparing your own quote against a national planning figure.
• 🔄 Program Design: Conservation and efficiency-linked payment programs increasingly reward documented application rates over flat volume purchases.
• 🏆 Input Efficiency: With DAP at $912.22/ton and ammonia at $915.50/ton (August 2026, farmdoc daily), the cost of a wasted pound of nutrient is higher than it was in 2025 — efficiency programs pay off faster at these price levels.

Frequently Asked Questions

Summary: How to Keep This Number Current

The 17-17-17 fertilizer price per ton is not a static figure — it moved from $734.15 to $746.55 per ton in Alabama between April and September 2025 alone (USDA AMS), while the wholesale ammonia behind it climbed from $786 to $915.50 per ton over roughly the same window into August 2026 (farmdoc daily). Any number on this page will be outdated by the time you read it; the sources it came from will not be.

• Farmers: Soil-test before buying a 1:1:1 blend, use the calculator above against your own quote, and compare it to the AMS Alabama benchmark rather than assuming it applies nationwide.
• Policymakers: Design efficiency-linked support rather than volume-based subsidies as per-ton costs climb.
• Agri-businesses: Adopt traceability and environmental impact monitoring to document efficient use for buyers and regulators.

Fertilizer pricing will keep moving with energy markets, mining supply, and regulation — that’s structural, not a one-year event. What stays useful is knowing exactly which agency publishes which number, how often, and how to convert it into your own field’s cost, which is what the sources and calculator above are built to do.
