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…

An example of ample light when temperature limits growth 21:25

4M ago21:25

21:25

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.

The combination of light (DLI) and temperature (GP) 43:50

4M ago43:50

43:50

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…
