In this episode, host Dr. Nataliya Shcherbatyuk sits down with Hadi Ghasemi, a Florida-based researcher, to explore how biodegradable plastic mulches (BDMs) are performing in real-world strawberry production systems.

Together, they discuss the promise and limitations of BDMs compared to conventional polyethylene mulch, insights from Florida field trials, and how environmental conditions like moisture, wind, and temperature influence mulch performance. The conversation also connects mulch technology with plant physiology, including photosynthesis, light reflection, and canopy microclimate—highlighting how these factors can impact yield and sustainability.

This episode offers valuable takeaways for growers, researchers, students, and anyone interested in sustainable horticulture, including how research can directly inform day-to-day production decisions and long-term environmental outcomes.

Tune in to learn:

• How BDMs compare to PE mulch in strawberry systems
• Key agronomic and environmental factors shaping mulch performance
• Why plant physiology matters when choosing mulch materials
• Practical insights for improving sustainability in specialty crop production

In this episode of Mulch Matters, host Dr. Nataliya Shcherbatyuk sits down with University of Tennessee researchers Dr. Sean Schaeffer and Jacob Clements to explore the unseen world beneath our feet, where biodegradable mulches, soil microbes, and even carbon isotopes reveal surprising stories.

Together, they break down what happens to soil‑biodegradable mulches (BDMs) once they enter the soil, how microbes physically and chemically transform plastic into smaller fragments, and why climate factors like temperature, moisture, and soil texture play such a big role in decomposition. Jacob offers an inside look at his cutting‑edge use of carbon‑13 and carbon‑14 isotope tracing, explaining how these tools help scientists pinpoint exactly where mulch‑derived carbon ends up and which microbes are doing the work.

The conversation also addresses farmers' biggest concerns when switching from polyethylene mulch to BDMs—including cost, aesthetics, degradation rate, and soil health impacts. Sean and Jacob share new findings from multi‑state research in Washington, Florida, Nebraska, California, and beyond, highlighting where BDMs break down fastest and why.

Finally, the episode explores the policy gaps surrounding biodegradable mulches in the U.S., what definitions and standards are still missing, and how future regulations could encourage more sustainable agricultural practices.

If you're curious about plastic pollution, soil health, microbial ecology, or the future of sustainable farming, this episode offers a clear and fascinating deep dive into the science shaping tomorrow's mulch technologies.

In this episode of Mulch Matters, host Dr. Nataliya Shcherbatyuk sits down with Dan Martens, Vice President of Novamont North America, for a deep and candid conversation about the past, present, and future of compostable mulch films. Drawing on more than 20 years of experience, Dan walks us through the evolution of compostable materials, the science behind biodegradation, and why understanding microplastics requires more logic than fear.

Together, they explore:

• How compostable mulch films have been studied for over two decades

• What long‑term soil research reveals about biodegradation and soil health

• Why marine biodegradability is complex — and what recent studies actually show

• The role of universities like Washington State University and UConn in advancing unbiased research

• The challenges and roadblocks facing BDMs in organic certification

• How standards like ASTM D6400 and ISO 17088 really work

• The innovations on the horizon, from multilayer films to biodegradable consumer goods

• Why new materials — not bans — are essential for a sustainable future

Dan also shares a powerful message about responsibility, scientific progress, and the importance of giving farmers real choices. This episode is packed with insight, clarity, and forward‑thinking ideas for anyone interested in soil health, sustainable agriculture, or the future of plastics.
