I discuss ATC blog posts, with 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.

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 depe…

You can expect soil organic matter to be 5% nitrogen, and you can expect from 1 to 4% of that organic nitrogen to mineralize in one year. You can also calculate estimated daily mineralization and sum it to get weekly, monthly, and annual totals.

Soil P, pH, and salinity are a few things that likely vary by depth in your rootzone. I've started recommending that 20% of putting greens tested be done with a sample divided at the 5 cm depth. Send the lab a 0-5 cm and 5-10 cm depth sample from that green, rather than the standard 0-10 cm depth sample. I discussed this blog post: https://www.asia…

I describe what we can learn from looking at five years of Mehlich 3 soil test phosphorus results from golf course putting greens, how to calculate the turfgrass speedo in a standard way, rather than in a chaotic way, and recommend an episode of the Cornell Turfgrass Show that asks if soil testing is the answer to all your problems. These are the l…

In this episode, I discuss sixteen year old bentgrass greens that have also gone sixteen years without P fertilizer. The greens are also free of Poa annua.

This is a follow-up to the episode last week when I mentioned that I was looking at snow outside, that the light would be ample for growth, but the temperatures were below freezing and thus temperature was limiting the growth. I discuss the new blog post that shows those light data. An example of ample DLI: https://www.asianturfgrass.com/post/an-ex…

The growth potential converts air temperature to a 0 to 1 (or 0 to 100%) scale. Of course, there are a lot more things that affect actual growth, including light, nitrogen, and water. I discuss these and why I'm not so convinced that adding a light factor to GP makes it more useful. The blog post discussed here is https://www.asianturfgrass.com/pos…
