Playability is what it is all about, isn’t it? At least for putting greens, one wants to have surfaces upon which the ball rolls at a certain pace, and which have a firmness that is appropriate for the conditions.
These are the predicted distributions and percentiles of total organic matter in the surface 2 cm (0.8 inches) of warm-season grass putting greens.
I include a plot for predicted organic matter of a random green of an unknown species.
What’s the common theme? You’ll hear all these topics discussed in recent episodes of Frank Rossi’s Frankly Speaking show on TurfNet, or in his presentation for the ASTMA.
My usual schedule is such that I don’t listen to podcasts on a regular basis.
Anything resembling thatch or mat is explicitly excluded from the soil organic matter measurement made on routine soil nutrient analyses.
That portion of soil organic matter is excluded because it is not measured.
There’s a ton of work done to modify the soil organic matter of turfgrass surfaces. Fertilizer, water, and increased light will allow the grass to grow and naturally increase the organic matter in the soil.
