The EW Podcast - Still Learning with Jerry
Jerry Brunetti was a founding partner of EarthWorks alongside Joel Simmons in 1988. At the time, Jerry owned an animal health care business in Northampton County, Pennsylvania, where Joel served as the County Extension Agent. Their friendship quickly grew, and Jerry became instrumental in helping Joel understand the value of Biological Soil Management.<br /><br />After EarthWorks was established, Jerry formulated two foundational products: the flagship Replenish 5-4-5 and the soil conditioner Kick. These products were originally intended to support a lawn care business, but Joel soon recognized that EarthWorks’ future was in manufacturing. From there, the company’s product deve...
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.<br /><br />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 prod...

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.<br /><br />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...
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.<br /><br />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...
