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.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ 2 Minute Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/

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.This week we’re joined by our friend Olee Poole, known by many as the Fescue Freak, to walk through the fertilizer program behind his exceptional three-acre fescue lawn outside of Charlotte. Olee relies exclusively on EarthWorks products and keeps his approach refreshingly simple. With just four core products, he feeds everything on his property, from fescue to thuja, tomatoes to blueberries.In this episode, Olee shares his exact fertilizer schedule, why he trusts carbon-based fertility, and how a soil-first program delivers consistent performance across turf and landscape plants.EarthWorks has been leading the conversation on Biological Soil Management for nearly 40 years, and this discussion highlights how simple, biology-driven programs can produce outstanding results.We’re wishing you a beautiful spring and look forward to working with you this season.EarthWorks For Home Products:EarthWorks For Home Sea3 Soil ConditionerEarthWorks for Home ProteinPlus Liquid Fertilizer (14-0-5) GalEarthWorks for Home Replenish Fertilizer (8-2-2) 25lb BagEarthWorks for Home Replenish Fertilizer (3-3-3) 25lb Bag

EarthWorks has returned from a fantastic week in Orlando at the GCSAA Trade Show and Conference, and by every measure, it was a tremendous success. On Wednesday afternoon, we welcomed friends from across the industry to our booth for cocktails. The space was packed from start to finish, and venue staff told us the EarthWorks gathering was the largest event on the show floor.Throughout the week, we spent valuable time with our distributor partners aligning goals for the year ahead while also connecting with countless turfgrass managers to answer questions, exchange ideas, and simply catch up. Those conversations remain the highlight of the show for our team. Reconnecting with longtime colleagues, some relationships spanning decades, and hearing both professional successes and personal updates is always deeply rewarding.One noticeable trend this year was the number of new companies entering the “organic” space. To us, this signals that EarthWorks’ nearly 40-year commitment to biological soil management continues to influence the industry in meaningful ways. We repeatedly heard from clients that EarthWorks has risen to the forefront of the carbon-based fertility movement, with more companies embracing a soil-first philosophy.As we shared stories from the week, the team also discussed opportunities to refine our approach for next year. And while there may be one notable exception, most of us are already looking forward to gathering again in New Orleans.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ 2 Minute Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/

Lawrence returns for a wide-ranging conversation that blends chemistry, physics, and biology with a few surprises along the way. Beyond being a world-class chemist and humate specialist, he shares stories from his past as a motorcycle racer and glass artist, proving great science often comes from creative minds.This episode takes a deep dive into amino acids: how they are produced, how they function within the plant, and why so much of the industry conversation is driven by hype rather than complete science. Lawrence explains how properly formulated amino acids can help reduce nitrogen inputs, improve efficiency, and support plants under stress.We also explore the real role of carbon in fertility programs. Too many products remain plant-focused instead of feeding the soil microbes that drive nutrient availability. By mimicking natural photosynthetic exudates, EarthWorks liquid technologies help create bioavailability in the root zone, even in the challenging environments of golf courses and sports fields.As always, Lawrence delivers a thoughtful and engaging look at how plants truly function and what it takes to build healthier, more resilient turf.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ 2 Minute Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/

Podcasting in the turf industry continues to gain momentum, and one of the standout successes is Turf Talk, hosted by Florida golf course superintendents Rob Uzar and Ty Robb. The show is broadcast live, which brings a unique set of challenges, from managing technology to handling unexpected guests or off-the-cuff moments. Rob and Ty embrace those challenges with quick thinking and humor, creating a loose, engaging format that makes the show as entertaining as it is informative.Turf Talk evolved organically from Ty’s early days hosting live turf conversations on Twitter (now X), where he would talk turf in the evenings and fellow grass growers would gradually jump in. One of the more memorable stories from our interview involved those early broadcasts starting at 7 p.m. Eastern. Just as Rob and Ty were ready to wrap up, turf managers from the West Coast would join, turning what was meant to be a one-hour show into a marathon that stretched well past East Coast bedtimes. Both hosts also reflected on their beginnings in turf management as teenagers, discovering a passion for the industry early on. Today, they continue to give back through the First Green program at their local high school, opening up their time and golf courses to help the next generation of turf managers explore the industry firsthand.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ 2 Minute Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/

In this episode, Kevin Hicks sits down with Jared Doerfler, founder of Hanna Golf Company, to explore his path from college golfer to launching a boutique, U.S.-based CNC-milled putter brand in Cedar Falls, Iowa. Jared shares how a background in manufacturing and a turning point in his personal life pushed him to leave a corporate VP role and bet on building something of his own within the game of golf.Jared walks through the hands-on realities of putter manufacturing, from teaching himself CNC machining to producing just six putters a day with a small team and two Haas mills. He explains why sound and feel are central to Hanna Golf’s design philosophy, how customization plays a key role in their process, and why staying focused on putters allows the company to maintain quality and intention over rapid scale.The conversation broadens to the state of the golf industry, touching on the post-COVID participation boom, domestic manufacturing challenges, and the growing influence of direct-to-consumer brands and storytelling through social media. Jared also discusses building an engaged audience through his Perfect Putt newsletter and the long-term value of supporting American manufacturing.Kevin and Jared close by reflecting on the future of golf, from junior and female participation to evolving attitudes around course maintenance and culture. They explore how less rigid maintenance standards, par-3 courses, and entertainment-driven golf experiences are reshaping the game while still honoring its traditional roots.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ 2 Minute Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/

It is rare these days to see someone stay in a job for more than 26 years, and even rarer to find a person who pours themselves into their work as if it were their own company. This month, we have been celebrating someone who has done all of that and so much more.More than 26 years ago, Lisa Kiefer walked into our office for an interview as an office support person. At the end of 2025, she will be retiring as the company’s Vice President. Over the years, many people in the EarthWorks extended family have spoken with Lisa on the phone or had the pleasure of working with her through one of her many responsibilities.As the owner and president of the company, I can honestly and humbly say that if Lisa had not walked into our office that spring afternoon, we may not be here today. She has been instrumental in our growth and direction. She kept the company moving forward while the rest of us were able to get out into the field and help turf managers discover the real value of Biological Soil Management.Many companies have someone like Lisa, but very few have someone who truly lives and breathes the work and carries such a deep passion for the mission we all embraced. She has been juggling balls and, more recently, elephants for her entire time with us. Unfortunately, elephants are not easy to juggle, so she has decided it is time to focus on her family, her six grandchildren, and life on the farm.To say we will miss her is an understatement. Expressing how grateful we are for her warm spirit, contagious laugh, and incredible work ethic comes effortlessly. We sat down in the same spot where we first met Lisa to record this podcast, sharing a few laughs, reminiscing often, remembering old friends, and even shedding a few tears.This is not goodbye by any means, but simply a change in the relationship Lisa has had for so long with the team and with all our friends at EarthWorks.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ 2 Minute Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/

Bob Wren has been a friend of EarthWorks for more than 35 years, and his career has taken him on a winding and memorable path through the turf industry. A graduate of the University of Maryland’s turf program, he began his career working alongside podcast alumnus Kevin Pryseski at Pine Ridge in Baltimore, Maryland. He then joined another podcast alumnus, Glenn Smickley, for the grow-in at the Robert Trent Jones Golf Club.From there, Bob took on construction of the Palmer-designed Fawn Lake, navigating a maze of new environmental restrictions that stretched the project into a four-year effort. After one more chapter as a golf course superintendent, he stepped away from the profession for more than a decade. Even while working in turf-related roles, he eventually realized it was time to follow the advice he had always given his sons: go back to the work you truly love.That decision led him south, trading snow for sunshine, and ultimately landing what he calls his dream job as superintendent at The Old Collier Club in Naples, Florida. His story is full of remarkable moments, including caddying for Arnold Palmer and mastering the challenges of managing Paspalum in high-sodium soils.Bob is always engaging, entertaining, and generous with his experience. This episode is a wonderful listen for anyone who loves golf, turfgrass, or the winding roads that lead people back to their passion.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ 2 Minute Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/

According to Lawrence Mayhew, the EarthWorks chemist, calcium is the most important nutrient in plant production. While that may be debated, Lawrence makes a strong case for why calcium deserves top billing in any fertility program.This episode begins with a discussion about ammonium sulfate and how it can release calcium from the soil colloid, making it more available to plants. Lawrence also explains how the presence of calcium in the soil triggers the release of root exudates, helping the element move into the plant.The conversation explores different calcium sources, such as various forms of limestone and gypsum, and how they behave differently in the soil. Lawrence dives into the redox chemistry of calcium, explaining its true function in the soil and why it does not directly affect pH the way many assume.The discussion wraps up with a look at how calcium operates within the plant and practical ways to improve calcium bioavailability.If you are a fan of soil chemistry and Biological Soil Management, this is a must-listen. Whether you are already a believer in the power of calcium or still skeptical, you will find this episode both informative and memorable.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ 2 Minute Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/
