Research for Healthy Soils Act

S 3623, the Research for Healthy Soils Act, authorizes federal grants to study microplastics in biosolids applied to farmland. The bill directs research on microplastic concentrations (under 5mm), wastewater filtration methods, impacts on crops/soil health, and microplastic movement in agricultural settings. It affects agricultural researchers, wastewater treatment facilities, and farmers through potential future data on land-applied biosolids. The bill also reauthorizes existing research programs through 2028, updating a 1990 law without changing current regulations.
