The National Corn Growers Association says US phosphate farm prices remain elevated and urges action on import tariffs. USDA projects fertilizer at 46% of 2023 corn operating costs, the highest ratio since the 1970s apart from 2008.
DAP and MAP prices rose sharply from 2020 to 2022 and have since declined.
High phosphate costs squeeze US corn margins, which can shift acreage toward soybeans and affect feed-grain supply. Tariff action would raise domestic phosphate prices, but this is an advocacy piece without a new policy decision.
After 151 past bullish policy events, DAP moved a median +0.0% over 5 sessions (50% higher; middle half -0.6% to +0.9%), and +1.9% over 20.
After 439 past neutral policy events, CORN moved a median +0.1% over 5 sessions (51% higher; middle half -1.3% to +1.2%), and +1.1% over 20.
