The EW Podcast - Joel Simmons with Lawrence Mayhew - The Chemistry Behind Healthy Soil
Lawrence Mayhew, “The Chemist of EarthWorks,” joins Joel Simmons for a wide-ranging conversation about humic substances, soil biology, nutrient efficiency, and the evolving science behind Biological Soil Management. Lawrence explains how humic substances moved from being poorly understood and difficult to label to becoming widely used for improving nutrient bioavailability and fertilizer performance.The discussion explores rhizophagy, the process through which plants cultivate microbes, bring them into their roots, extract nutrients, and release them back into the soil to repeat the cycle. Lawrence and Joel also examine the importance of enzymes, trace elements, carbon diversity, micronization, and complex product formulations in creating biologically active soils and longer-lasting turf responses. The central message is that reducing fertilizer inputs requires more than simply applying less product. It requires changing the soil system so microbes, chemistry, and physical soil conditions work together more efficiently.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ EW Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/

The EW Podcast - Jack Higgins & Kirk Castner - Behind the Scenes at EarthWorks
Jack Higgins sits down with EarthWorks’ Kirk Castner for a behind-the-scenes look at how the company has evolved over the past decade and where it's headed next. Rather than focusing on agronomy alone, this episode explores the people, manufacturing, logistics, and philosophy that allow EarthWorks to continue meeting growing demand while maintaining product quality.Jack and Kirk reflect on their years with EarthWorks and discuss the tremendous growth the company has experienced, expanding from a single granulation facility to multiple production plants across the United States. They explain how increasing demand from golf courses has expanded into sports turf, parks, universities, hydroseeding, construction, and tree care, requiring significant investments in new manufacturing capacity.The conversation dives into the unique partnership with Rose Acre Farms and how EarthWorks turns poultry manure into premium compost-based fertilizers through a true circular economy. Kirk explains the lengthy composting process, new composting technologies, odor reduction efforts, expanded compost storage, and additional granulation facilities currently under construction.They also discuss the global fertilizer market, including how geopolitical events can dramatically impact synthetic fertilizer availability and pricing, while highlighting the advantages of sourcing and producing organic fertilizers domestically. The discussion reinforces EarthWorks' long-standing commitment to building healthier soils rather than simply supplying nitrogen.On the liquid side of the business, Kirk shares how automation, robotics, and improved production systems have increased efficiency while preserving the small-batch manufacturing process that keeps EarthWorks liquid products biologically active and effective.The episode concludes with a discussion about EarthWorks' Early Order Program, why planning ahead benefits both customers and manufacturing, and how these improvements ultimately help turf managers receive consistent, high-quality products while reducing production bottlenecks. Throughout the conversation, Jack and Kirk emphasize that every investment EarthWorks makes is focused on supporting customers, improving soils, and making turf managers' jobs easier.

The EW Podcast - Joel Simmons & Jack Higgins with Dr. James White, Rutgers University
Dr. James White of Rutgers University joins the EarthWorks Podcast to discuss the fascinating world of rhizophagy, a process in which plants actively farm, consume, and extract nutrients from soil bacteria and fungi. His groundbreaking research has helped identify and explain this remarkable relationship between plants and soil microbes, changing the way we think about plant nutrition and Biological Soil Management.Throughout the conversation, Dr. White walks through the entire rhizophagy cycle, explaining how plants bring microbes into their root cells, extract nutrients, and then release them back into the soil to continue the cycle. This process not only feeds the plant but also stimulates the formation of root hairs, allowing roots to explore more soil for water and nutrients.The discussion also explores the surprising role that some disease-causing organisms can play within a healthy biological system and why maintaining an active, diverse soil microbiome is essential for long-term plant health.Whether you manage golf course turf, sports fields, landscapes, or any other plants, this episode provides remarkable insight into one of the most important discoveries in modern plant science. It offers a deeper understanding of why soil biology matters and why Biological Soil Management continues to transform the way we grow healthier, more resilient plants.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ EW Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/

The EW Podcast - Joel Simmons with Moe Robinson - turfRad
Former golf course superintendent and self-proclaimed "Turf Head" Moe Robinson brings her passion for turf management and technology to this conversation. Now serving as Customer Success & Agronomy Advisor with turfRad, Moe shares how this innovative moisture mapping system is helping superintendents make smarter irrigation decisions through data instead of guesswork.Mounted on a utility vehicle or other course equipment, the turfRad system collects thousands of moisture readings across the turf in a single pass, creating detailed maps that identify exactly where water is needed and where it is not. Armed with this information, turf managers can fine-tune irrigation, improve consistency, conserve water, and reduce unnecessary applications.Moe explains how the technology first gained traction in regions where water is limited and expensive, but also discusses why courses in wetter climates are finding tremendous value by identifying overly saturated areas and improving overall moisture management. She also talks about turfRad's partnership with Toro and how the system is helping superintendents better understand what is happening below the surface.Moe's enthusiasm for turf management and emerging technology shines throughout this conversation, making this an informative and engaging episode for anyone responsible for growing and managing high-quality turf.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ EW Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/

The EW Podcast - Joel Simmons with Ryan Severidt
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 work at hand and doing whatever was necessary to keep the course performing at a high level.He later moved to The Olde Farm in Bristol, Virginia, where higher elevations and a cooler climate provided a different set of opportunities for managing bentgrass. His next move to Woodmont Country Club introduced a new challenge: maintaining both bermudagrass and zoysiagrass in the Mid-Atlantic region, where changing weather patterns continue to influence turf management decisions.Ryan discusses the increasing adoption of warm-season grasses in the region, the challenges presented by the winter of 2025, and how environmental conditions continue to shape management strategies. He also shares his approach to leadership, emphasizing education, communication, and helping team members understand the "why" behind every decision. By creating a culture of learning, Ryan has built strong teams and developed future industry leaders.This conversation offers valuable insights into turf management, leadership, and adapting to changing conditions in one of the most dynamic growing environments in the country.Visit EarthWorks at: https://www.earthworksturf.com Podcasts: https://www.earthworksturf.com/earthworks-podcasts/ EW Turf Talks: https://www.earthworksturf.com/2-minute-turf-talks/
