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 certain companies use oversimplified or misleading soil interpretations to sell products
The scientific standards for a real soil test and what makes it trustworthy
How proper soil testing differs from marketing-driven “DIY” interpretations
What homeowners should actually look for when deciding if their lawn needs fertilizer, lime, or amendments
How to evaluate online lawn-care information and avoid advice that is not evidence-based

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.
