Miller-Meeks Leads Charge to Lower Fertilizer Costs for Iowa Farmers

Jul 06, 2026

Congresswoman Mariannette Miller-Meeks (IA-01) released the following statement after the Administration suspended duties on phosphate fertilizer imports, which will lower input costs for American farmers by an estimated $1.82 billion every year.

Background

Phosphate fertilizer is a critical nutrient for crop production, but the United States is not self-sufficient in its production. Domestic output has declined significantly in recent decades while demand continues to grow, making imports essential to meeting the needs of American agriculture.

Global supply chains have faced increased strain due to geopolitical instability, including the Russia-Ukraine war and unrest in the Middle East. These disruptions have limited access to key inputs and contributed to higher prices for farmers.

Existing duties on Moroccan phosphate imports have further constrained supply and reduced competition in a highly concentrated global market. According to analysis from Texas A&M University’s Agricultural and Food Policy Center, these duties increased fertilizer costs for U.S. farmers by approximately $6.9 billion between 2021 and 2025.

Field Talk Friday | Dr. John Murphy | Root Exudates, Soil Biology, and How Plants Recruit Microbes

Most of us spend our time managing what we can see above ground—plant height, leaf color, stand counts, and yield potential. But the deeper you dig into agronomy, the more you realize that some of the most important processes driving crop performance are happening just millimeters below the surface.

In this episode of Field Talk Friday, Dr. John Murphy continues the soil biology series by diving into one of the most fascinating topics in modern agronomy: root exudates and the role they play in shaping the microbial world around plant roots.

Roots are not passive structures simply pulling nutrients out of the soil. They are active participants in the underground ecosystem. Plants constantly release compounds into the soil—sugars, amino acids, organic acids, and other molecules—that act as both energy sources and signals for soil microbes.
