Jack Higgins visits Churchill Downs for an on-site conversation with Track Superintendent Jamie Richardson about the unique challenges of managing one of horse racing’s most demanding turf surfaces. Jamie explains how the track transitions from cool-season grasses to Ironcutter Bermudagrass during the summer, using the strength of the Bermuda root system to build a more stable, resilient racing surface focused on horse safety and performance.
Jamie also discusses the evolution of the sand-based turf course, which was rebuilt in 2021, and how sprigging, DryJect, organic matter management, drainage, aerification, and fertility have helped improve the track year after year. The results are showing: Churchill Downs ran 108 turf races during the spring meet, and the course performed exceptionally well even following heavy rainfall.
The conversation also looks at Jamie’s EarthWorks fertility program, including Myco-Replenish 3-3-3, Replenish 8-2-2, Replenish 5-4-5 and C3, with a major emphasis on building roots, maintaining stability, replenishing nutrients in the sand profile, and supporting turf recovery under heavy traffic.
After the Churchill Downs interview, Jack shifts to late-summer turf management and discusses why August is an important time for recovery, aerification, overseeding, carbohydrate storage and preparing both warm- and cool-season turf for the months ahead.
