The post discussed in this episode is https://www.asianturfgrass.com/post/surface-hardness-correlations/. I planned to discuss this one also but decided to hold that discussion for another episode: https://www.asianturfgrass.com/post/density-plots-clegg-putting-greens/. I was joined by Andrew McDaniel (https://twitter.com/drumcturf) for this discussion.

I also mentioned the chart from Steve Isaac showing the target firmness levels for links course championship events. You can see that chart in this post: https://www.asianturfgrass.com/post/three-things-to-do-with-om246-data-right-now/

• Joe joined me to talk about one of the least read blog posts of 2018. This one, about soil microbes being in an environment with ample carbon, but being limited by nitrogen: https://www.asianturfgrass.com/post/microbes-live-carbon-rich-nitrogen-poor-world/ 
• We also discussed this post, "How much carbon and humus are in the soil?" https://www.asianturfgrass.com/post/how-much-carbon-and-humus-are-in-the-soil/

I find it really useful to consider nutrient applications as ratios rather than as quantities. Read more in this post: https://www.asianturfgrass.com/post/how-i-recommend-fertilizer-ratios/

This is an obvious concept but the implications are complex. If soil organic matter accumulates more rapidly in young soils, and if one wants to manage soil organic matter most efficiently, then it makes sense to keep the soils in an older, rather than in a younger, state.

I discuss my visit to (and seminar at) the University of Florida, and consider whether soil organic matter content stability over time might be related to the inherent accumulation rate of said organic matter.

I discuss tests for soil organic matter, and explain the distinction between those tests and a different kind of test for total organic material by depth. I also talked briefly about a new MLSN film.

• I discussed the "A Tale of Two Tests" blog post which describes the value of measuring soil organic matter (SOM) and also measuring total organic material by depth (#OM246): https://www.asianturfgrass.com/post/tale-two-tests-soil-organic-matter/
