It's tough to manage cool-season putting greens when ΔGP is less than 0

The ATC Doublecut with Micah Woods

This episode introduces ΔGP, which is cool-season grass growth potential minus warm-season growth potential. Too many days like that and you won't bother trying to grow cool-season grass anymore. Also, best time of the year to soil sample, a superb podcast from Chris Tritabaugh, and a careful look at the difference between soil organic matter and total organic material.
