Iceland

I’ve been making estimates of N mineralization from soil organic matter for the past few years using the method described by Gilmour and Mauromoustakos in Nitrogen mineralization from soil organic matter: a sequential model.

I took 82 flights in 2016, for a total of 221,494 km (137,000 miles), and I’ve just mapped them. That’s more than 5 times the circumference of the earth. Routes flown once are more blue, and the routes flown more often are more red.

I made a map of all the flights I took in 2015.1 After seeing the map, I scrolled through my photos from these places. It was an extraordinary year for studying grass around the world.

I think temperature has more of an influence on turf growth, and I will use some data from Iceland to show why. This concerns the situation when there is not shade from buildings or trees, and looks at a situation when the light is more than sufficient for growth, but the grass does not grow.

Here’s a mystery about green patterns in straight lines on greens in Iceland. This is Iceland in early May. There was still snow on the mountains around Reykjavik. The greens in question are primarily fine fescue.

I was in Iceland to speak with the Icelandic Green- and Groundskeepers Association about turfgrass nutrient requirements. See my notes about turf in Iceland, along with presentation slides and handout, here.

I was in Iceland to speak with the Icelandic Green- and Groundskeepers Association about turfgrass nutrient requirements. Read more about the seminar, and download the presentation slides and handout, in this report about a method for estimating turfgrass nutrient requirements.

On my first visit to Iceland, I spoke at a meeting of the Icelandic Green- and Groundskeepers Association at beautiful Keilir Golf Club in Hafnarfjörður. View from behind the 18th at Keilir GC.
