Measure exact topdressing effect, and requirement, by checking total organic matter by depth.
When the total organic material is known at time A and at time B, the accumulation rate can be calculated. By accounting for the sand that was applied between time A and time B, another accumulation rate can be calculated: the organic matter accumulation rate independent of sand application.
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.
A recent conversation about putting surfaces in Japan led to discussion of topdressing amounts and frequency.
The Greenkeeper 2018 has course maintenance summaries for 17 courses in Japan. I mapped the locations of those courses by zip code.
Frank Rossi and Dan Dinelli had an interesting conversation on Turfnet Radio. I learned a few things, and I even agree with some of what they discussed. But not all of it.
