S3 E65 Tinfoil Turfgrass: Soil Testing Goes Extreme!
In this video I take a close, critical look at "Data-Drive Lawn Care" (https://www.youtube.com/watch?v=pjRXNcIi3Hk) and share my honest thoughts on what works — and what doesn’t. I break down the arguments, highlight where I think the logic falls short, and offer my own perspective on the topic. 🔎 What I cover: Key claims made by the original creator Moments where I agree — and moments where I respectfully disagree Glaring omissions and what I believe should have been addressed My own take: what’s convincing, what needs more...

S3 E63 Tinfoil Turfgrass: How to Evaluate Claims When The Salesman Knows More Than You.
In this video, I provide an in-depth, evidence-based critique of the nitrogen-efficiency product RDX-N and the claims made in the promotional video circulating online. If you’ve ever wondered whether biostimulants, nitrogen enhancers, or “metabolic activators” actually work in real-world turfgrass or crop management, this breakdown is for you. I review the product’s marketing claims, examine the data presented in the official RDX-N brochure, and explain what the science really says about nitrogen uptake, nitrogen metabolism, and plant physiology. But this video is more than a review of one product—it's a lesson in how to evaluate a...

S3 E59 Tinfoil Turfgrass: Don't Use This Soil Test!
In this episode of Turfgrass Epistemology, I review a popular lawn-care website article and an accompanying YouTube video that teach homeowners how to interpret a soil test that is, in reality, scientifically invalid for making nutrient decisions. These resources look polished and authoritative, but the advice they provide is fundamentally flawed — and following it can lead to unnecessary product applications, wasted money, and incorrect assumptions about soil health. I’ll walk through both the website and the video step-by-step and explain: Why the soil test they promote is not valid for nutrient recommendations How cert...

S3 E54 The Rise and Fall of University Turfgrass Programs
In this video, I explore the history and current state of university turfgrass programs—from their rise during the post-war boom in golf, parks, and sports fields to their decline in recent decades. I explain how turfgrass faculty positions are created and filled, what factors lead to the loss of those positions, and why many programs are now disappearing altogether. I connect the dots between enrollment trends, industry funding, and the shifting priorities of universities that have left turfgrass science struggling to survive. Most importantly, I discuss what the turfgrass community—educators, managers, and industry leaders—can do to revers...

We’ll look at how someone can present information that is technically true, yet still mislead by reframing the issue or knocking down an argument no one actually made. This breakdown shows how a conman can be both truthful and deceptive at the same time—a powerful reminder of why critical thinking matters in turfgrass science, lawn care, and beyond.

In this episode of Turfgrass Epistemology, we dive into a study from Oregon State University that looked at how turfgrass species and mowing height affect water requirements in western Oregon. The results might surprise you—tall fescue and perennial ryegrass significantly outperformed fine fescues when it came to conserving water. We’ll break down the data on evapotranspiration replacement, irrigation intervals, and how mowing height can influence your watering schedule. Should you mow higher? Should you convert to tall fescue? This video gives you practical, science-backed guidance on how to choose and manage turfgrasses for water conservation.

S3 E18 Do Irrigation Intervals Affect Turfgrass Rooting?
In this video, we delve into the 1985 study by Peacock and Dudeck, titled "Effect of Irrigation Interval on St. Augustinegrass Rooting," published in the Agronomy Journal. The research examines how varying irrigation intervals—every 2, 3, 4, or 6 days—impact the root mass and length density of St. Augustinegrass. Interestingly, the study found that root development remained unaffected across these intervals, suggesting that less frequent irrigation may not compromise root growth. These findings have significant implications for turfgrass irrigation practices, potentially leading to more efficient water usage without sacrificing turf quality.

Constants in the turfgrass growth potential equation
The PACE Turf growth potential equation has one variable (the actual air temperature) and two constants. The constants are optimum air temperature and a term for variance that controls the shape of the curve as the actual temperature moves away from the optimum temperature. It's a little more complicated than that, because the constants change depending on whether you are making the calculation for cool-season grass, warm-season grass, and on whether you are using the Fahrenheit temperature scale or the Celsius temperature scale.The blog post discussed is https://www.asianturfgrass.com/post/calculating-gp/PACE Turf climate appraisal...

TENNESSEE TURFGRASS: Kyley Dickson, Ph.D. When it comes time to reseed or renovate an area in the fall or spring, selecting the most suitable grass variety can be a challenging task. Over the years, plant breeders and seed companies have made significant advancements in enhancing their grasses through plant breeding. These improvements include developing grasses with resistance or increased tolerance to specific diseases, better drought tolerance, and an enhanced ability to withstand extreme climatic conditions. However, verifying these claims is crucial. To address this, various research programs conduct tests on new turfgrass varieties under different conditions...

What the ATC Doublecut is all about
Hi. I'm Micah Woods, chief scientist at the Asian Turfgrass Center. I've been studying turfgrass around the world since the 1990s, and I've been writing about turfgrass on my blog in three decades now. That's more than a thousand posts about all kinds of turfgrass topics --- playing conditions, fertilizer, soil tests, grass selection, sustainability, frost delays, growth rate --- pretty much everything that I've been interested in.In this ATC Doublecut series, I'm discussing some of these same topics. Mostly it's the new blog posts, the most recently published ones, but I may take a second...

"Color, Transfer, and Application Parameters of Turfgrass Colorants" with Garland (Drew) Pinnix. In kindergarten, we're taught that colors can be one of seven colors of the rainbow. Later, we learn fun colors like purple mountain majesty and get excited when our friend brings a 50-pack of crayons. In reality though, color is much more complex, a mixture of hue, brightness, and saturation. Drew Pinnix thinks a lot about color, specifically in relation to turfgrass. Most of the time, the beautiful turfgrass we see at golf courses or football fields is due to careful management by professionals trained...
