The EW Podcast - Joel Simmons with Dr. Mike Fidanza - Managing Fairy Ring and Soil Biology

This week we welcome Dr. Mike Fidanza from Penn State University, a globally recognized authority on fairy ring in turf. Our conversation digs into how this fungus establishes itself in the soil and why the traditional explanations only tell part of the story. For years, fairy ring was blamed solely on decomposing organic matter. While that plays a role, Dr. Fidanza explains why the issue runs deeper. He challenges the idea that carbon-based fertility causes fairy ring and instead points to the complexity of the soil biome and microbial interactions. Much of his current research focuses on how soil biology, moisture management, and drought stress influence the development and severity of the disease. He recently explored these themes in Golf Course Industry in his article, The Interactions of Plant Soil Microbes Under Drought Stress. A key takeaway from our discussion is that fairy ring often thrives where biological processes are not fully supported. When nitrification slows and ammonium lingers, fungi can take advantage of that imbalance. Healthy biological activity helps keep nutrient cycling moving and reduces the conditions that favor disease. This conversation reinforces what we’ve long discussed: managing turf challenges starts below the surface. Soil biology, carbon availability, and balanced nutrient cycling all play a critical role in creating resilient turf systems.
