Managing heat stress in cool season sports turf / Jeff Haag, Turf Specialist, Xavier University.

"The cool season(C3) grasses of Kentucky bluegrass and perennial ryegrass are commonly used as sports turf grass on high maintenance athletic fields, with tall fescue being used on some lower maintenance fields, such as intramural athletic fields, however, any warm season(C4) athletic field that is overseeded with a cool season grass, typically perennial ryegrass, becomes a cool season athletic field for several months. One of the disadvantages of cool season grasses is that they can become stressed during times of high heat, although, tall fescue has been shown to be more heat tolerant. We will look at the physiological, biochemical, and molecular mechanisms of heat stress in cool season sports turf as well as methods, mostly nutritional, to help combat it."--Amazon.com description. https://www.amazon.com/Managing-Heat-Stress-Season-Sports/dp/1793935505
