ClipVol

You may be familiar with the grammar of greenkeeping. That’s what I call the approach to turfgrass maintenance that focuses on growth rate. As I wrote in the preface to the book with that title:

I’ve been looking at some growth ratio data, and I’ll share a few ideas here. Jason Haines introduced this as the turfgrass speedo, and I think that’s a good name for it.

I’ve taught a seminar that goes through 10 things I’ve learned about clipping volume. One of those things is this: keeping track of the total quantity of clippings year to date and as annual totals is useful.

A correspondent wrote with this inquiry related to estimating the value “a” in the MLSN fertilizer rate equation.1 Specifically, the “a” value is the expected plant use of the element over the time period for which the fertilizer recommendation is being made.

I was a guest on The Tie podcast where I spoke with Walker Simas about “Turf for Dummies.” Well, not quite to that extreme. We still managed to cover a lot of greenkeeping topics, but perhaps I explained the topics in a less technical way.

This is one of those blog posts that I finally can move from the list of notes about what I might write about, to the published and completed section. > [2020-08-29 Sat] On my run this morning from […] to […] I was thinking that a little bit of quantitative like OM246, knowing nutrient supply, clipvol, it goes a long way in leading to improved turf conditions.
