S4 E17 Organic Fertilizers and Turfgrass Disease

About this episode
This episode discusses the impact of organic fertilizers on turfgrass disease and establishment based on recent research.
In this video, I break down the research article “Soil Amendments and Fertilizer Source Effects on Creeping Bentgrass Establishment, Soil Microbial Activity, Thatch, and Disease.” We examine whether organic fertilizers, poultry meal, and humate soil amendments really improve bentgrass establishment, microbial activity, disease suppression, and thatch management on sand-based greens. The results show that readily available nitrogen from synthetic fertilizers produced faster establishment and generally better turf quality, while organic programs increased microbial activity but did not improve establishment or consistently suppress disease. If you manage golf greens, creeping bentgrass, or sand-based rootzones, this study provides important insights into fertilizer sources, soil amendments, microbial activity, and turfgrass disease management. #turfgrass #bentgrass #golfcoursemanagement #turfgrassscience #fertilizer #soilscience #dollarspot Become a member of Turfgrass Epistemology and support turfgrass research:www.youtube.com/@TurfgrassEpistemology/join Voicemail:859-444-4234 Apple Podcasthttps://podcasts.apple.com/us/podcast/turfgrass-epistemology/id1717271379 Spotify…
