nitrogen

If you’ve got some organic matter in the soil, then you will get some nitrogen (N) that the grass can use from it. This is called mineralization. As the organic matter decomposes, some of the N that was in the organic matter is converted into inorganic forms in the soil.

One of the many ways to learn is through conversations with industry veterans. Their wisdom about how turf is managed now, and how it was managed in the past, can be invaluable.

Is there a way to estimate how much nitrogen is harvested in clippings? Is there an equation to use to adjust a nitrogen fertilizer rate based on the Turf GvX?1 Yes, there are ways to do both of these.

I bought a new book last year in January and got my hands on it in December. It’s the Compendium of Turfgrass Diseases, Fourth Edition, published by APS Press in 2023.

I know this can use more explanation, because I’ve heard people refer to “their MLSN N” as being some amount. When I first heard that, I was taken aback, because nitrogen (N) is explicitly not part of MLSN.

I sometimes talk about maximum N. You may have heard me refer to the standard amount of N. I discussed that with Michael Bekken in this ATC Doublecut episode. What do I mean by these quantities of N?

An anonymous golf course superintendent sent me this message: I’m blown away by the quality of these surfaces with an amount of nitrogen I would’ve thought was far too small.

From July 3 to July 10, I visited 11 golf facilities in Japan. I asked some basic questions to the greenkeeper at each course. The answers to the questions help me to understand what the greenkeeper is working with, and how many resources are available to get the job done.

When a lot of nitrogen is applied relative to plant demand, I guess. The article Creeping bentgrass surface properties following aerification by Hubbard et al. reports the results of an experiment looking at various aerification treatments, tine diameters, and tine spacings on a `Crenshaw’ creeping bentgrass green at Clemson, South Carolina.

For a few years now, when I have private discussions about the type of putting green maintenance that involves few or no holes punched in the surface and minimal sand topdressing, I often hear this response.
