About this episode
This episode discusses the effects of calcium silicate on turfgrass diseases based on a specific study.
In this video, I break down the study “Evaluation of Calcium Silicate for Brown Patch and Dollar Spot Suppression on Turfgrasses.” We examine whether calcium silicate (Si fertilizers) actually suppress turfgrass diseases like brown patch and dollar spot. The results show that calcium silicate did not reduce dollar spot and, in some cases, actually increased brown patch severity, likely due to nutrient imbalances rather than any true disease suppression effect. If you're interested in silicon fertilizers, disease control, and evidence-based turfgrass management, this is a must-watch breakdown. #turfgrass #dollarspot #brownpatch #soilscience #fertilizer #turfgrassscience #golfcoursemanagement 📌 https://www.gofundme.com/f/TurfgrassEpistemology Thank you for being part of this community and for supporting evidence-based turfgrass science.
