This podcast explores how we know what we know about turfgrass science. If you are a lawn care operator, sport field manager, sod producer, golf superintendent, or a home owner, this podcast provides evidence-based information to help you better manage your turfgrass.
Travis Shaddox hosts Turfgrass Epistemology, a education show with 281 episodes published.
Why do generic soil reports feel surprisingly accurate? In this video, we explore the Forer Effect and discuss how vague, universally true statements can create the illusion of personalized insight—whether in personality
Why do people conform to group pressure even when they know the group is wrong? In this video, we explore Solomon Asch's landmark conformity study, Opinions and Social Pressure (1955), and reveal what his famous experime
Does summer nitrogen really make brown patch worse in tall fescue? In this interview, Dr. Jada Powlen discusses her 2024 study and explains why cultivar selection may be more important than nitrogen rate for managing bro
In this video, I break down the classic study “Optimizing Manganese Fertilization for the Suppression of Take-All Patch Disease on Creeping Bentgrass.” We examine whether manganese applications can suppress take-all patc
In this video, I break down the study “Evaluation of Calcium Silicate for Brown Patch and Dollar Spot Suppression on Turfgrasses.” We examine whether calcium silicate (Si fertilizers) actually suppress turfgrass diseases
In this video, I break down the research on biological and oil-based fungicides for dollar spot control in turfgrass. We examine whether products like biological fungicides, mineral oils, and plant-based treatments actua
In this video, I break down a lawn care discussion on nitrogen fertilizers and turfgrass performance, separating what’s scientifically sound from what may be oversimplified. We take a closer look at how nitrogen source,
In this video, I break down the “DirtBooster Organic Lawn and Garden Treatment” video from How to With Doc and take a closer look at the claims around soil microbes, biochar, humic substances, and “super compost.” The pr
In this video, I break down a popular lawn care video on soil testing, pH, and nutrient recommendations and separate what’s useful from what may be misleading. We take a closer look at how soil test results are interpret
In this video, I break down a lawn care video making the rounds online and separate what sounds right from what’s actually supported by turfgrass science. We take a closer look at the claims, the reasoning behind them, a
In this video, I respond to comments and emails and answer a common question: Why do dog urine (pet) spots last so long in turfgrass? We break down the science behind nitrogen burn, salt injury, and recovery limitations
In this episode, I sit down with Rob from Turf Therapy and Cam from Elevated Lawnscapes to talk all things lawn care, content creation, and turfgrass management. We discuss their approach to building great lawns, lessons
In this video, I break down the study “Influence of Calcium and Nitrogen Fertilizer on Creeping Bentgrass Infected with Dollar Spot.” We examine whether it is calcium or lime that actually suppresses dollar spot, how it
In this video, I break down the classic study “Microbial Populations and Suppression of Dollar Spot Disease in Creeping Bentgrass with Inorganic and Organic Amendments.” We take a close look at whether organic fertilizer
In this episode, I interview Dr. Scott McElroy (Auburn University) about weed control in turfgrass, including best practices for herbicide timing, resistance management, and how herbicides interact with insecticides. We
In this video, I break down a Floratine Masterclass where Tim Cartwright discusses a common claim about calcium availability in soils. I examine the argument, the science behind calcium in turfgrass soils, and whether th
In this video, I break down the research article “Soil Amendments and Fertilizer Source Effects on Creeping Bentgrass Establishment, Soil Microbial Activity, Thatch, and Disease.” We examine whether organic fertilizers,
In this video, I review the classic turfgrass study “Dollar Spot Severity, Tissue Nitrogen, and Soil Microbial Activity in Bentgrass as Influenced by Nitrogen Source.” We take a close look at whether organic fertilizers
In this video, I review the research article “Strategies for Increasing Ferrous Sulfate Efficacy Against Dollar Spot of Creeping Bentgrass.” We examine how ferrous sulfate (FeSO₄) can suppress dollar spot, how applicatio
In this episode of Turfgrass Epistemology, I critically examine the article “Exploratory Study on the Foliar Incorporation and Stability of Isotopically Labeled Amino Acids Applied to Turfgrass” (Agronomy, 2020) and use
