Constants in the turfgrass growth potential equation

The PACE Turf growth potential equation has one variable (the actual air temperature) and two constants. The constants are optimum air temperature and a term for variance that controls the shape of the curve as the actual temperature moves away from the optimum temperature. It's a little more complicated than that, because the constants change depending on whether you are making the calculation for cool-season grass, warm-season grass, and on whether you are using the Fahrenheit temperature scale or the Celsius temperature scale.

What is The Doublecut with Micah Woods?

I discuss turfgrass management topics, usually starting with a blog post, sharing supplementary information, stories, and the reasons why I thought the topic was worth writing about, and worth reading about. Thus, a doublecut of these topics. This covers grass selection, playability, and all the work done to create a certain type of turfgrass surface.
