I remember the days vividly when I was a superintendent, when I thought the greens were great. We had planned all our spray applications and topdressing events with the goal of maximizing the performance of the putting surfaces. Mowing and rolling practices were adjusted to get our greens in peak condition for our key events. After the roller would leave the green, I would linger for a few moments, maybe even hit a few putts, and enjoy the deeply satisfying feeling that our team had produced fantastic greens.

I often wondered if that kind of greens performance was sustainable for longer than a couple days during an event. If I had data on how the greens were performing before and after those events, would that have helped me extend those windows of peak surface performance?

Regrettably, I never kept track of all the things we did to prep for those events, nor did I record the measurable outputs such as green speeds, clippings, and firmness values. It could have been that I was just too busy, but more likely, I just wasn’t that forward thinking.

When I visit courses now as an agronomist, I am impressed by the amount of data that superintendents and their teams are recording. Collecting and measuring clippings, recording green speeds, fertilizer and plant growth regulator (PGR) inputs and sand topdressing applications are becoming more and more common. Over time, this data allows superintendents to see trends clearer and make better-informed decisions on surface preparation. Knowing how many days a growth regulator application actually regulates growth is important. Measuring clippings allows you to see how weather, fertilizer and PGR applications affect growth rates at your course. Consistently measuring green speeds will also reveal trends in how your cultural programs are impacting surface performance.

If you’re not already doing some sort of data collection on greens performance, 2021 is the year to start. Recognizing the value of this data, the USGA has developed USGA Surface Management to assist you with the recording and analyzing of surface performance data. Whether you decide to use USGA Surface Management or not, collecting data can benefit your greens management program. If you have questions about data collection, reach out to a USGA agronomist to learn how easy it is to get started at your course.
