Research for Healthy Soils Act

S 2500, the Research for Healthy Soils Act, authorizes federal research grants to study microplastics (plastic particles under 5mm) in biosolids applied to farmland. It directs the USDA to fund specific research on microplastic concentrations in agricultural soil, wastewater treatment methods to remove microplastics, impacts on crops and soil health, and microplastic movement in farmland. The bill does not regulate microplastic use but supports scientific understanding of potential agricultural effects. It affects agricultural researchers and institutions receiving these grants, extending related research funding through 2031. The focus is strictly on gathering data and developing solutions, not on policy changes for farmers or regulators.
