Bill Kreuser from GreenKeeper joined me to discuss how much grass grows, the complicated problems involved when sand is mixed with clippings, growth regulator adjustments, leaf nutrient content, soil…

Frank Rossi, Ph.D. is the New York State extension turfgrass specialist at Cornell University. We talked about mentorship, potassium, turf nutrition, smoothness of putting greens, dogma, data, budget…

The PACE Turf growth potential equation has one variable (the actual air temperature) and two constants. The constants are optimum air temperature and a term for variance that controls the shape of t…

You can expect soil organic matter to be 5% nitrogen, and you can expect from 1 to 4% of that organic nitrogen to mineralize in one year. You can also calculate estimated daily mineralization and sum…

This episode introduces multiple experiments that have demonstrated a link between rapid measurement of clipping volume and the clipping yield. Clipping yield is typically expressed as dry weight per…

Andrew McDaniel has been watching webinars to get education points, and some of these have been about management of soil organic matter on putting greens. We discussed a particular article and whethe…

Here are four specific things to look at with total organic material by depth (#OM246) test results.

The four posts discussed in this …

When the cool-season growth potential (GP) is lower than the warm-season GP, the difference between them (the ΔGP) will be negative. In this episode, I discuss ΔGP and three different ways to think o…

I wondered what NotebookLM could do, so I created a couple notebooks. One has the title “Global Soil Survey,” and in that notebook I uploaded articles and documents I’ve written about MLSN and the GS…

Grant Saunders is the course superintendent at Hamilton Golf Club in New Zealand. He has successfully overseen a green species conversion from Poa annua to browntop bentgrass (Agrostis capillaris). W…

When you know the rate at which organic material is accumulating in the rootzone, you can adjust sand topdressing rates with more precision. You can also start to check how any changes in maintenance…

T-Jay Creamer is the golf course superintendent at Olympic View Golf Club in western Canada. He joined me to discuss tournament golf maintenance and the grammar of greenkeeping.

We discussed this ATC …

A month ago Joe Gulotti and I walked the fairways and greens of the Montchanin Course at Dupont Country Club. I wrote a blog post about that, and we discussed my visit in this episode.

Blog post: http…

You can sometimes, perhaps more often than you would think, find soil under good turf to have lower nutrient content than does soil under poor quality turf. In this episode, I explain why that is, wh…

Independent turfgrass researcher John Dempsey, Ph.D., joined me to discuss evaluating treatment effects and the importance of having a good control. We talked about diseases, nutrition, and this blog…

Dr. Henry Qu, partner and data scientist at Oxbridge Economics, joined me to talk about data analysis, and statistics, and how to try to learn things in turfgrass science. We discussed NTEP, posterio…

Jon Wall, golf course superintendent at Shanqin Bay, joined me to discuss doing more work to make grass better, rather than doing less. And also about what I'd want everyone to do, which is doing the…
