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 agronomic claims using critical thinking and epistemology.
In turfgrass, agriculture, and lawn care, new products appear constantly—each claiming to increase yields, improve nitrogen efficiency, reduce inputs, or boost plant health. Without strong critical thinking skills, it’s easy to be misled. Epistemology—the study of how we know what we know—helps protect you when you’re confronted with products, technologies, or scientific claims you’ve never heard of.
By the end of this video, you’ll understand:
If you’re a turfgrass manager, agronomist, sports field manager, lawn care professional, or scientifically curious homeowner, this channel will help you make smarter, evidence-driven decisions.
