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
The goal of this video isn’t to criticize people — it’s to highlight why bad testing leads to bad decisions, and how to empower homeowners with the ability to recognize valid, science-based soil information.
If you’ve ever wondered whether the soil advice you see online is trustworthy, or how to distinguish real science from clever marketing, this episode will give you a clear, reliable framework for making informed choices.
