Phosphate is a critical nutrient for crop production, and right now farmers are paying prices that threaten their bottom line. This bill puts money back in the hands of the people feeding this country.
What it does.
S. 4418 lowers the cost of phosphate fertilizer for Kansas farmers by ending the Biden-era duties on imports from Morocco. Texas A&M's Agricultural and Food Policy Center estimates those duties have cost American farmers $6.9 billion since 2021. The U.S. does not produce enough phosphate to meet domestic demand, so the duties have squeezed supply in a market growers cannot exit. The bill ends the order, restores access to competitively priced phosphate, and ensures timely refunds of previously collected deposits.
Doc introduced S. 4418 on April 28, 2026 as the lead Senate sponsor, with Sens. Grassley, Hyde-Smith, and Ernst joining as original cosponsors. The House companion, H.R. 8583, is led by Rep. Mariannette Miller-Meeks. The bill is now in the Senate Finance Committee.
Endorsements at introduction: National Corn Growers Association, American Soybean Association, American Farm Bureau Federation, National Cotton Council, USA Rice, Sorghum Growers, and the National Association of Wheat Growers.
Fertilizer can run up to 40% of operating cost for a corn grower and 38% for wheat. A 20% drop in phosphate cost is real money on the input invoice before a single bushel ships. Kansas is the #1 wheat state and #1 sorghum state in the country.
