Fertilizer, Diesel Costs Remain Elevated Heading Into Fall

Fertilizer and diesel prices remain well above recent-year levels, adding pressure to farmers making fall input decisions for the 2027 crop.

USDA data analyzed by the University of Illinois shows anhydrous ammonia averaged $915.50 per ton on August 7, up 16% from a year ago.  DAP averaged $912.22 per ton, 7% higher than last year.  Meanwhile, potash prices have been more stable, averaging about $500 per ton.

Diesel has been more volatile, while prices have been hovering around $5.00 per gallon nationwide, diesel prices across the Northwest have been higher, with Washington's average near $6.12 per gallon.

University of Illinois researchers say farmers may want to diversify fertilizer purchases rather than waiting for prices to fall. They also recommend reviewing application rates, using soil tests, and following maximum-return-to-nitrogen recommendations.
