Establishing faster-growing, durable football fields
Date:5/13/2008

am found that turf seeded with 100% perennial ryegrass was less sensitive to planting dates than Kentucky bluegrass turf. Summer and spring plantings provided similar quality and dormant seedings resulting in superior quality to Kentucky bluegrass-based dormant seedings.

Additionally, simulated traffic studies revealed that different levels of traffic did not affect turf species proportions. The most consistently desirable results were obtained with a mixture containing 70%-80% Kentucky bluegrass and 30%-20% perennial ryegrass. The best results for mixtures dominated by Kentucky bluegrass came from fields seeded in late summer.

Stier added that perennial ryegrass could be planted in spring and provided ideal ground cover with few weeds, but mixtures in which Kentucky bluegrass seed comprised 50% or more of the turf needed to be planted the preceding summer. Dormant seedings did not perform well, leading to relatively poor ground cover and significantly higher weed populations.

Summarizing the impact of his teams research, Stier said: The research outcomes can allow school systems to prepare better bids for construction and renovation of sports fields, making the fields more likely to meet expected performance standards and ultimately reduce costs to the school districts.
