Key things to know about high quality turf surfaces

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.

Total organic matter at the surface of warm-season grass putting greens

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.

Total organic matter at the surface of cool-season grass putting greens

This is a time of year when there is a lot of sand going down on putting greens, and sometimes a bit of coring too. The purpose of all this work?

What do Ninja tines, PoaCure, ClipVol, the Smith-Kerns disease model, ball roll, and MLSN have in common?

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.

Numerical notes from Nikanti GC

I spent a morning with Brad Revill at Nikanti GC last month. I wanted to see the course, get some measurements, see the clipping volume measurement, and talk about turf management with Brad.

Variation in rootzone organic matter (humus) from point to point on the same green

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.

How much does total organic matter vary within the same green?

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.

Simple, idiot proof, and inexpensive

I had a great email exchange last December. It gets at what is really required, in a couple key areas, to produce high quality surfaces. And that might be less than you think.

Soil organic matter: a bullet list

These are some key things I’ve learned after studying organic matter (OM) for a few years. This is about organic matter in the context of playing conditions—how a ball reacts when it hits the surface.

Catching up with my reading

A friend sent me a link to the Business Mirror’s Golf Section and said I should check it out. I just did that, and found a picture of myself above a report about Nutranta’s Best Practices seminar.
