The ATC Doublecut with Micah Woods

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 it to get weekly, monthly, and annual totals.

Matteo Serena is the Senior Manager of Irrigation Research and Services for the USGA. We discussed drip irrigation, growth regulators and soil surfactants, water use, overseeding, and bermudagrass vs. zoysiagrass water use.

We discussed this ATC blog post: https://www.asianturfgrass.com/post/zoysia-and-water-use/

We also discussed these articles:

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 of summer duration.

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 GSS. I let the model generate a few different audio summaries of this project. And I uploaded the text to A Short Grammar of Greenkeeping, and I let the model produce an audio summary of that book.

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). We discussed that, and the role of OM testing, and sand topdressing, and soil pH, and greenkeeping in New Zealand.
