10-34-0 (liquid polyphosphate starter fertilizer) is priced at $3.20–$4.10 per gallon in spring 2026 — up 20–30% from a year ago. Prices track MAP and ammonia feedstock costs. At typical corn application rates of 3–5 gallons per acre, starter fertilizer adds $9.60–$20.50 per acre to spring crop budgets.

10-34-0 is produced by reacting ammonia with phosphoric acid to create ammonium polyphosphate solution. MAP and ammonia are the primary feedstocks. Both rose 15–30% in 2026, pulling 10-34-0 prices with them.
10-34-0 requires specialized tanker transport. As with all liquid fertilizers, freight costs have increased in 2025–2026, adding $0.20–$0.40/gallon to delivered prices.
Essentially all 10-34-0 is applied at planting in April–May. There is no off-season application window, which means buyers have zero timing flexibility and absorb the full spring premium.
10-34-0 + sulfur blends (e.g., 7-24-5-2S) have gained popularity. Blending costs have increased, but agronomic benefits maintain demand even at elevated prices.
10-34-0 is a liquid ammonium polyphosphate solution used as a starter fertilizer. The analysis (10% N, 34% P2O5) makes it a phosphate-intensive product applied in-furrow or 2×2 at planting.
10-34-0 is $3.20–$4.10 per gallon in spring 2026. Delivered prices to the farm are in the $3.50–$4.10 range depending on haul distance.
Typical corn starter rates are 3–7 gallons per acre for in-furrow or 2×2 placement. At $3.60–$4.00/gallon, starter fertilizer adds $10.80–$28.00/acre to corn input costs.
Dry MAP (11-52-0) can replace 10-34-0 on an equivalent phosphate basis, but requires broadcast application — you lose the starter placement advantage. Agronomically, starter placement typically shows a 3–8 bu/acre response on corn.
