Key Takeaways
- A first-of-its-kind U.S. field trial is testing Class A biosolids fertilizer for industrial hemp grain and fiber production.
- Early observations show taller plants and thicker stalks compared to conventional urea fertilizer.
- The study measures yield, soil carbon sequestration, PFAS uptake, and remediation potential.
- Partners include the University of Illinois Urbana-Champaign, MWRD, and Flura Inc.
- Replication in 2026 will support publication and national guidance on sustainable nutrient management.
Biosolids Fertilizer Takes Center Stage in Nationwide Hemp Research Effort
A unique field trial led by the University of Illinois Urbana-Champaign is examining how biosolids fertilizer can support hemp cultivation for fiber and grain. Conducted in partnership with The Metropolitan Water Reclamation District of Greater Chicago (MWRD) and Flura Inc., the research evaluates the agricultural and environmental performance of EPA-approved Class A biosolids in real-world field conditions.
The program, formally titled Evaluating Environmental Benefits of Growing Hemp with Biosolids, is designed to understand how nutrient-rich biosolids can influence crop performance, soil health, and sustainability outcomes across key indicators, including carbon sequestration and PFAS absorption.
Early Field Observations Show Strong Hemp Performance
Initial visual assessments from the Champaign-Urbana plots indicate that hemp grown with biosolids appears taller and has thicker stalks than crops grown with standard urea fertilizer. The project completed its first full harvest and analysis in November 2025, with a second year of replication planned for 2026.
