MAP (monoammonium phosphate) is priced at $620–$720 per ton across U.S. Corn Belt markets in spring 2026, running 18–28% above year-ago levels. China phosphate export restrictions reduced global supply, and MAP trades at a modest discount to DAP due to its lower nitrogen content.

MAP production in China was directly curtailed by export restrictions. Global MAP supply tightened in parallel with DAP, though MAP saw slightly less price appreciation because it serves more specialized applications — starter fertilizers and blends — with less elastic demand.
Like DAP, MAP uses ammonia as a feedstock. Elevated ammonia costs in 2026 raised MAP production costs worldwide and supported prices even in markets not directly affected by China export restrictions.
MAP is widely used in starter fertilizer blends (10-34-0, 11-52-0). Corn planting in April–May drives concentrated demand, creating a seasonal premium that persists through June.
MAP buyers often blend with potash for complete NPK programs. Relatively stable potash prices from Canadian sources provided some offset to the higher MAP cost per acre.
MAP is $620–$720 per ton at Corn Belt retail in spring 2026. NOLA barge prices are $600–$685/ton.
MAP (11-52-0) is a high-phosphate granular fertilizer used for pre-plant broadcast, starter blends, and row applications. Its low salt index makes it safe for seed-zone placement.
MAP is 11-52-0 (11% N, 52% P2O5). DAP is 18-46-0 (18% N, 46% P2O5). DAP has more nitrogen per ton; MAP has more phosphate. On a cost-per-unit-of-phosphate basis, they are typically within 5% of each other.
With China restrictions holding through August 2026, spring prices are at seasonal highs. Buyers who need product for planting have no choice. If you can defer to fall 2026 application, waiting may yield 10–15% savings.
