Putting green organic matter by depth in the soil

I watched the Greenkeeper App meeting about organic matter, and I recommend you do too. The video has Doug Soldat, Bill Kreuser, and Roch Gaussoin talking about soil organic matter, rootzones, sand topdressing, and turf performance.

Sand topdressing by growth rate and clipping volume

Does this sound about right? Matching sand topdressing to the growth of the grass works out pretty good when applying 1 cm3 of sand for every 1 cm3 of clipping volume.

Ball bounce on greens after 7 days of rain

I’ve been at Keya Golf Club for the KBC Augusta tournament this week. Yesterday afternoon I watched some shots during the first practice round, and took a few videos of ball reaction on the greens.

A pleasant day, with an unpleasant termination

Last week I spent a few days in Fukuoka. I was there for the 103rd Japan Amateur Golf Championship. On the the morning of July 5, I recorded this video of a short iron shot landing on the 16th green at the host venue, Keya Golf Club.

Predicting organic matter in turfgrass soils

Jason Haines has been sharing some ideas on his Turf Hacker blog, and one that I think is especially interesting is the idea that one can precisely match the topdressing sand quantity to the growth of the grass.

Learn the rules like a pro, so you can break them like an artist

Some years ago I shared some articles that I often referred to or recommended, and I called that Five articles every greenkeeper should read. As I look at this list of articles now, I’m reminded of the familiar maxim about understanding the rules before breaking them.

The case for reactive greenkeeping

I’ve been sitting on this idea for a long time, and I decided today would be a great day to write about it. You can decide if I’m serious. When we first study turfgrass management, we tend to learn a proactive approach.

Topdressing frequency on golf course putting greens in Japan

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.

Sand topdressing and growth potential

PACE Turf have prepared this spreadsheet that takes inputs of average temperatures and a maximum monthly topdressing rate, and gives outputs of estimated monthly and annual topdressing sand amounts. It is a metric version of this:
