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.

The turf GvX for checking grass growth with Jason Haines 34:15

Jason came up with the GvX idea in a flash of inspiration that he describes here. This is the actual growth of the grass compared to the expected growth of the grass, and it has surprising practical implications. We discussed the development and use of the #TurfGvX in this episode.

Calculation of the average daily temperature 18:53

23 روز پیش18:53

18:53

A common way to calculate average daily temperature is to take the sum of the daily maximum and daily minimum temperatures, and to divide by two. A better statistical approximation of the average temperature is to take measurements made every hour and then to find the mean value of those continuous measurements. This blog post shows a comparison of the three methods for 2024 data at three locations: https://www.asianturfgrass.com/post/calculating-average-daily-temperature/ Read more about all kinds of turfgrass topics at https://www.asianturfgrass.com/ Find a suite of decision-making tools at https://www.paceturf.org/ Get free ATC newsletters at https://www.asianturfgrass.com/newsletter/ More about ATC soil tests at https://www.asianturfgrass.com/project/soil-tests/…

Although turf research is often done with fertilizer treatments applied at constant rates and on a fixed calendar schedule, that way of supplying nutrients seems strange to me now.

Bracketing #ClipVol for a desired range of green speed 33:49

Green speed varies because of many factors. One of those factors is clipping volume. I discuss that relationship and give some advice for those getting started with clipping volume and wanting to know how to adjust it.

Constants in the turfgrass growth potential equation 25:23

24 weeks پیش25:23

25:23

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. The blog post discussed is https://www.asianturfgrass.com/post/calculating-gp/ PACE Turf climate appraisal forms at: https://www.paceturf.org/journal/climate More about GP and the variance term at https://www.asianturfgrass.com/post/what-is-variance-in-growth-potential-equation/ Read more about all kinds of turfgrass topics at https://www.asianturfgrass.com/ Get ATC newsletters at https://www.asianturfgrass.com/newsletter/ Turfgrass information and decision-making tools at https://www.paceturf.org/ PACE Turf YouTube channel at https://www.youtube.com/user/paceturf ATC's YouTube channel at https://www.youtube.com/asianturfgrasscenter More about ATC soil tests at https://www.asianturfgrass.com/project/soil-tests/…
