## Summary

**Creates a federal definition and regulatory framework for plant biostimulants.** The bill would amend FIFRA to add clear definitions for plant biostimulant, nutritional chemical, and vitamin hormone product and to narrow what counts as a plant regulator. - Farmers and growers would get clearer rules on which products qualify as plant biostimulants. The bill defines them as substances or microorganisms applied to seeds, plants, soil, or growth media that support natural plant processes and improve nutrient use, stress tolerance, or yield. - Manufacturers and regulators would face new categories and exclusions under FIFRA. The bill would add three new defined terms and direct the Environmental Protection Agency to revise its subchapter E regulations within 120 days after enactment. - Researchers and land managers would see a new federal soil health study. The Secretary of Agriculture would assess which biostimulants and practices best boost organic matter, reduce nutrient runoff and volatilization, restore soil bioactivity, and aid carbon sequestration, and must report results to congressional agriculture committees within two years after funds are available.
