Summary

What This Bill Does
The Research for Healthy Soils Act authorizes the U.S. Department of Agriculture to make research grants to study microplastic pollution in biosolids (treated sewage sludge) that are applied to farmland. The bill adds microplastics research as a priority area and extends funding authorization for agricultural research programs through 2031.

Who Benefits and How
Universities and agricultural research institutions benefit by receiving new grant funding to study microplastics in agricultural settings. Environmental testing companies benefit through contracts to conduct surveys and analyze microplastic concentrations in biosolids and soil. Wastewater treatment technology companies benefit from funding to develop and test filtration systems that can remove microplastics before biosolids are applied to farms. Farmers who use biosolids as fertilizer benefit indirectly by getting better information about potential soil health impacts.

Who Bears the Burden and How
Federal taxpayers bear the cost of funding these research grants through USDA's budget. Biosolids management companies and wastewater utilities face increased scrutiny and potential regulatory risks if the research reveals harmful effects of microplastics in their products, though they may also benefit from solutions developed through the research.

Key Provisions
- Authorizes USDA grants for surveys measuring microplastic concentration, particle size, and chemical composition in biosolids applied to farmland
- Funds development and testing of wastewater treatment techniques to filter out or biodegrade microplastics before agricultural use
- Supports research on how microplastics in biosolids affect crop growth and soil health
- Studies microplastic fate, residence time, and transport patterns in agricultural soils
- Extends authorization for USDA high-priority research and extension programs from 2023 to 2031
