This bill, known as the Fertilizer Transparency Act of 2026, amends the Agricultural Marketing Act of 1946 to establish a comprehensive mandatory price reporting program for fertilizer . Its primary goal is to provide timely, accurate market information to farmers, facilitate informed marketing decisions, and foster competition within the fertilizer industry. Under this program, corporate officers of manufacturers and wholesalers of nitrogen, phosphorus, potassium, and other fertilizer products must report prices and quantities weekly to the Secretary of Agriculture. This reporting must clearly delineate between domestic and foreign sources of fertilizer marketed in the United States, with cooperatives and non-manufacturer retailers exempt from mandatory reporting but allowed voluntary participation. The Secretary is required to make the reported information publicly available at least weekly, on both a national and, where appropriate, a regional or statewide basis. Additionally, the bill directs the Secretary to establish a program within Market News to conduct weekly surveys of retail fertilizer prices , obtaining commercially available estimates and providing benchmarks for local prices. All collected data, encompassing both mandatory reports and retail survey findings, must be summarized and made available weekly on an easily accessible dashboard for farmers and market participants. Strict provisions protect confidential business information and the identity of reporting entities, ensuring data is aggregated before public disclosure, and the Act explicitly states it does not modify existing antitrust laws.
