ClipVol

Measuring the growth rate by clipping volume. Really.

My books about greenkeeping, turfgrass science, clipping volume, and MLSN.

A pound of nitrogen. That’s a substantial amount of N, right? Apply a pound of N in a single application and that’s going to create a lot of growth—way too much growth in most cases—and may lead to some thatch production.

I use the turfgrass growth potential (GP) all the time. I make use of the GP for all kinds of things, like predicting sand topdressing amounts, comparing locations, predicting nutrient use, checking overseeding dates, estimating mowing requirements, and many more.

On November 2 & 3, I’ll be at the Portuguese Greenkeepers Conference in Porto. You can register for the conference at the APG website. Here are three quick notes. 1. The five exciting topics I’ll be discussing I’m going to lead a series of short seminars at the conference.

One way that I like to look at clipping volume measurements is to plot the cumulative amount of clippings collected. This enables one to compare clipping amounts year to year.

Here are some common questions about turfgrass management: how much fertilizer should I be adding at this time of year? how often should I topdress with sand? how often should I be verticutting?

This can seem a bit abstract, the whole growth ratio thing. In this post, I go step-by-step through the reasoning behind this, and explain exactly which problem this solves. There’s a common question that people have when they start measuring the exact amount of clipping volume.

A question came up about optimum clipping volume and whether that quantity of clippings changes by season. That amount must change for any location at which there are seasonal changes in the weather.
