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 Podcasthttps://open.spotify.com/show/1cTpdrChToeEFAOX9wkXFI iHeart Radio Podcasthttps://www.iheart.com/podcast/1323-turfgrass-epistemology-129043524/ Podbeanhttps://turfgrassepistemology.podbean.com/ Online consultingCalendly.com/TravisShaddox TwitterTwitter.com/TravisShaddox EmailTravisShaddox@gmail.com Turfgrass Programs and Extension Service Information:https://www.usna.usda.gov/assets/images/as_pdf_image/LandGrantColleges.pdf","meta_description":"In this video, I break down the research article “Soil Amendments and Fertilizer Source Effects on Creeping Bentgrass Establishment, Soil Microbial Activi…","key_points":[],"chapters":[],"topics":[],"duration_seconds":4039,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/turfgrass-epistemology-6708747/episodes/s4-e17-organic-fertilizers-and-turfgrass-disease/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/turfgrass-epistemology-6708747/s4-e17-organic-fertilizers-and-turfgrass-disease.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
