Fertilizer Prices
The middle cash price per ton that farm co-ops post for each product. Every price names its co-ops, region and date. Right now: Kansas and Wisconsin co-ops only, posted Sep 10 to Oct 14, 2026.
Data: prices farm co-ops post, read each weekday; each price names its co-op.
What Kansas and Wisconsin co-ops are posting
Each co-op’s own posted prices. Cash is each co-op’s own (cash, cash discount or cash pickup). Call to confirm.
Far from the other co-ops: Mulvane Cooperative Union’s Urea ($840). Counted, but the middle price is shown so one co-op does not pull the figure.
Prices from Two Rivers Coop, McCune Farmers Union Coop, Mulvane Cooperative Union, Farmers Coop and Synergy Cooperative. Every co-op and every posted price.

Build your fertility bill
Enter your crop and yield goal, and pick the phosphate and nitrogen you use if you know them. This prices out the program to replace what the crop removes, using the co-op prices above. Phosphate and potash are costed at crop removal. Nitrogen is an N budget estimate at a yield-goal rate, not a rate recommendation; for a corn N rate use the Corn N Rate Calculator (MRTN).
Enter a yield goal to see your per-acre fertility bill.
How this is calculated
Cost per pound of nutrient = price ÷ (2000 lb/ton × grade %). Each nutrient is sourced from the cheapest product carrying it; nitrogen already supplied by your phosphate source (e.g. MAP) is credited before pricing urea.
Crop removal (lb/bu): Corn P₂O₅ 0.38, K₂O 0.29 · Soybeans 0.80 / 1.40 · Wheat 0.50 / 0.35: grain removal from UW Extension A2809 Table 4.2, the same numbers the nutrient removal calculator uses. Nitrogen uses a yield-goal rate (default 0.9 lb N/bu corn, adjustable; soybeans fix their own N), so the N line is a budget estimate, not a rate recommendation. Most Corn Belt extension services set corn N rates with the Corn N Rate Calculator (MRTN). These are benchmarks, not a soil-test recommendation. Your soil tests, credits, and agronomist override them.
Why prices move
Why fertilizer prices move
Natural gas drives nitrogen costs (urea, ammonium sulfate). Phosphate (MAP) prices follow global mining supply, with Morocco and China as dominant producers. Potash is dominated by Canada, Russia and Belarus; K-Mag comes from a single U.S. mine in Carlsbad, New Mexico, so any export disruption moves prices fast. Pelletized lime is more local, set by quarry output and freight. Seasonal demand spikes before spring and fall applications regardless of global fundamentals.
What the NOLA barge price means
NOLA barge prices reflect fertilizer trading at New Orleans barge terminals and are a benchmark for the wholesale market. The prices on this page are retail cash prices co-ops post for farmers. What you pay is your own dealer's delivered price.
Timing fertilizer purchases
Historically, fall and early winter offer softer urea and phosphate prices before spring demand builds. But natural gas direction, global supply, and tariffs can override seasonal patterns. A common approach: lock in 50–60% of needs in fall at a price you can live with, leave the rest flexible for spring.
How these prices affect break-evens
For corn at 180 bu/acre applying 160 lbs actual N as urea: a $100/ton price increase adds roughly $17/acre to input costs, or about $0.10/bu to your break-even. That dime comes straight off your margin.
