US Nitrogen Costs Diverge: DAP Up 24% and Ammonia Up 11% in a Week While Urea Slides 8%

US fertilizer quotes for the week ending October 12 show a sharp split inside the nutrient complex. DAP rose $187.30, or 24.2%, to $961.83 per short ton, anhydrous ammonia gained $90.17, or 11.1%, to $905.67, and UAN 28% added $102.00, or 20.5%, to $600.00. UAN 32% rose $64.71 to $622.14. Against those moves, urea fell $60.94, or 7.7%, to $730.00, potash slipped $35.69 to $535.20 and ammonium sulphate eased $6.43 to $574.12. MAP was almost flat at $1,020.22, up $3.99. The pattern points to phosphate and nitrogen solutions tightening while urea, the most widely traded nitrogen product, gave back part of an earlier advance.

The cost pressure is landing on a farm sector that is already being compensated for weak crop prices. USDA said on October 7 that Farm Service Agency Agriculture Risk Coverage and Price Loss Coverage programmes will generate roughly $13.8 billion in gross payments to eligible producers for the 2025 crop year, a record for the safety-net programmes. Record ARC and PLC outlays imply that 2025 revenue and price triggers were hit broadly, which is consistent with the large carryout now weighing on grain markets rather than with any shortage-driven rally in crop values.

Grain fundamentals are doing little to offset input costs. US corn stocks on September 1 were reported at 53.2 million tonnes, about 35% higher than a year earlier and above market expectations, so the market is harvesting new crop on top of a larger old-crop carryover rather than into a tight pipeline. Chicago corn fell about 2% on the week and CBOT maize traded below $5 a bushel, dragging export parity values lower for competing origins. Wheat has been better supported: Black Sea shipping remains constrained and Russia has rejected proposals for a truce on attacks against port infrastructure, though buyers are re-emerging, with Saudi Arabia taking around 683,000 tonnes in its latest tender after cancelling the previous one.

The practical read-through for input budgeting is that phosphate and nitrogen solutions now carry the marginal cost, while urea is the one major product giving buyers relief. Southern hemisphere demand is watching the same complex: Australian urea was reported down 4% on the week to around A$832 a tonne but still about 11% above a year earlier, and South African landed urea indications were quoted higher near R9,000 a tonne into Durban. With northern hemisphere harvest pressure capping crop revenue and phosphate costs rising at a double-digit weekly pace, the fertilizer-to-grain price ratio is deteriorating again heading into 2027 planting decisions.
