We have been tracking the clipping yield when we mow greens each day. On the North Course, Nate has been tracking it for all the greens that they mow. We have taken that average data for all 18 greens and broken it down into sand-based greens versus soil-based greens. On the chart below you can see 2 vertical lines. These vertical lines represent rain events. Turf typically responds to rain about 2 days after a rain event. You can see that very well on these graphs. If you are wondering why the discrepancy in the soil versus sand greens? It is strictly soil temperature driven. Sand based greens are much colder than soil based, and you get higher growth rates from the soil-based greens because they hold in the heat. We are anxious to see what happens over the next couple of weeks as the sand-based greens warm up and the temperatures warm up. Hopefully, the lines come closer together.
This is all new data for us, and we are just getting started with it. Our goal would be to get the greens to all have the same growth rates. They do mirror each other but the sand greens do not produce the same clipping yield. By doing this we will be able to see how our inputs effect growth rates and how our plant growth regulators effect growth. More to come as we try to dial this in.
