While Eric Reasor was collecting the data on ball roll dispersion in Thailand – read yesterday’s post for more about that – I collected data on the the same greens.

When Eric Reasor flew from Tennessee to Thailand, he brought along measuring tools to assess how golf balls roll across putting greens. He visited 22 golf courses in 5 days.

I led a seminar in which I discussed how much one can expect grass to grow. During that seminar, I said something like: grass can always grow more, but turfgrass managers restrict the growth rate by supplying less nitrogen fertilizer than the grass can use.

In a series of quotes about BCSR, this conversation ensued. Allan Dewald asked about MLSN, and Travis Shaddox brought up the probability of response. We won’t provide a response probability for MLSN because it is not a fertilizer calibration.

Looking down at Hat Lamai from the 8th tee at Royal Samui. I’ve written about a hypothesis for identifying the most sustainable grass. Paul Johnson wrote with some feedback on this hypothesis, and a few questions.

On 17 July 2016, I was in the Tokyo area with Jim Brosnan. The daily light integral (DLI) in Tokyo that day was 14.2 mol/m2. Jim asked me if it was exceptionally cloudy that day.

A fine-bladed manilagrass growing faster than Tifeagle bermudagrass. I’ve written about zoysia growing faster than bermuda. Mike Richardson asked: so, the real question…is that better? “Slow growing” has always been one of my favorite traits of zoysia…

If you work with warm-season grasses, you will want to have a look at this article by Reasor et al. on the variability of hybrid bermudagrasses used on putting greens.

I was wondering what the effect was. I expected a 1 or 2 °C decrease in nighttime soil temperature in drier soils, compared to soils with more water. I didn’t find it.

The MLSN guidelines were developed from a large dataset of soil tests collected from good-performing turf. You’re probably familiar with the MLSN guideline as a minimum level, with fertilizer recommended to make sure the soil doesn’t drop below the guideline.
