Today I explained the same calculation about sand topdressing for the third time, so I need to write a blog post on this topic.
This is following the method of David Robinson, who says when you’ve written the same code 3 times, write a function; when you’ve given the same advice 3 times, write a blog post; and when you’ve done the blog post 3 times, write a book.
Last November I saw a creeping bentgrass nursery in Japan. The nursery had been fumigated to kill seeds in the soil before the bentgrass seeds were planted.
I was surprised to see, scattered across the nursery, plants with big leaves that clearly were not creeping bentgrass.
A few years ago Blake Meentemeyer and Brian Whitlark wrote about fertilizer in the Green Section Record. I’ve recommended this article before, in a post on the Viridescent blog. I highlighted in that post a case study from the article—a “facility in the Las Vegas area” reduced putting green fertilizer cost by a staggering 82%.
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.
Last year I wrote about a soil temperature turfhack. The soil temperature is almost always between the day’s high and low temperature.
The soil temperature at a 5 cm depth immediately after planting manilagrass stolons on 22 April.
It’s always a good idea to know what the soil temperature is. One can measure it, or one can be confident that the average daily soil temperature close to the surface (5 cm, or 2 inch depth) is higher than the daily low temperature, and lower than the daily high temperature.
