In this episode of Turfgrass Epistemology, I review and respond to comments, emails, and TikTok messages I’ve received throughout 2025 related to turfgrass science, soil fertility, nutrient management, and common turf industry claims.

From thoughtful questions to recurring misconceptions, this video highlights what turf managers, lawn care professionals, golfers, and homeowners are asking—and where confusion often arises when science meets social media. I address trends I’ve seen across platforms, clarify misunderstandings, and explain why certain claims persist despite decades of research.

Topics discussed include:

This episode is not about calling people out—it’s about slowing down, adding context, and explaining how we know what we know in turfgrass science. Whether you’re a golf course superintendent, lawn care operator, researcher, or homeowner trying to make better management decisions, this discussion is designed to help you separate evidence from noise.

If you’ve emailed me, commented on YouTube, or left a TikTok comment in 2025, there’s a good chance your question—or one just like it—is addressed here.
