The EarthWorks Podcast

On this episode of the EarthWorks Podcast, we sit down with Ryan Severidt, Superintendent at Woodmont Country Club in Rockville, Maryland. Ryan's career has taken him from the Midwest to some of the most challenging turf environments in the country, managing both cool-season and warm-season grasses across a variety of climates and conditions.

Ryan began his career at Kinloch Golf Club in Richmond, Virginia, one of the first all-bentgrass golf courses built that far south. Despite skepticism from many in the industry, Kinloch established itself as a world-class property. As Ryan explains, success came from focusing on the...

EarthWorks began extensive soil testing nearly 40 years ago with one goal in mind: creating healthier soils that support stronger biological activity. By understanding soil chemistry through detailed testing, turf managers can improve soil structure, increase air and water movement, and build an environment where microbes thrive. It’s the foundation of the EarthWorks philosophy: Balance the Chemistry Feed the Soil.

In this episode, Kevin Hicks and Joel Simmons dive into the importance of soil testing and how real data can help turf managers make smarter fertility decisions. They discuss how compaction, nutrient balance, and water quality all influence so...

On this week’s EarthWorks Podcast, Joel Simmons talks with Scott McLean, Plant Healthcare Business Developer for Northeast Operations at The Davey Tree Expert Company.

Like many turf professionals, Scott didn’t begin his career with a clear roadmap. After taking a job at a local golf course, he quickly fell in love with the turf industry. He spent twelve years in golf course management, earned his turf degree from University of Massachusetts Amherst, and built a strong foundation in traditional turf management. But as family priorities changed, Scott began looking for a career path that offered a bett...

On this week’s EarthWorks Podcast, Jack Higgins catches up with longtime friend and superintendent Josh Saunders for a ride around Lancaster Country Club as they discuss spring conditions, tournament preparation, and the 64th Compher Cup.

For over 30 years, EarthWorks has helped turf managers successfully establish golf courses and sports fields during construction and grow-in. Our soil-first approach has consistently delivered stronger rooting, more efficient fertility programs, and long-term performance.

Sand-based root zones, however, present a unique set of challenges. They are naturally low in mineral content, have limited nutrient holding capacity (CEC), and provide little to no carbon to fuel soil biology. The result is reduced microbial activity, an overreliance on synthetic nitrogen during grow-in, and the development of excessive, unmanageable thatch.

In this episode, Kevin Hicks sits down with Joel...

In this episode, Jack Higgins sits down with horticulturalist Tim Hollowell to explore the deeper connection between soil health, plant performance, and practical horticulture. Tim shares his perspective from years of hands-on experience, breaking down how soil biology, structure, and nutrient balance all work together to influence plant success.

The conversation moves beyond surface-level plant care and dives into what’s really happening below ground. From managing soil conditions to understanding how plants respond to their environment, Tim offers insights that apply across landscapes—from turf to gardens and beyond.

This episode is a great listen for...

Construction is booming across Florida, and for Director of Agronomy Nate Maurer, the clock is ticking toward a major course reconstruction set to begin next year. After years of planning and finalizing a partnership with golf course architect Andy Staples, the project will kick off with a full turf removal in late spring.

When asked what advice he’d offer superintendents considering a renovation, Nate didn’t hesitate: communication is everything. Years before breaking ground, he began educating members on the “why” behind the project. He led tours across the course, highlighting problem areas and even using a soil pro...

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...

This time of year never fails to inspire. The sun starts climbing higher, soil temperatures begin to wake up, and the first hints of green remind us why we love this work.
