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.

I’ve been writing a monthly article for ゴルフ場セミナー (Golf Course Seminar) magazine since May 2008. That’s 99 articles so far, and 118,518 words. The best of these will be published in English, sometime; for now they are only available in Japanese.

This is a useful reference from Purdue Extension on water that goes into the spray tank. From the guide: “Water often comprises ninety-five percent (or more) of the spray solution. What affect might it have on product performance?
