Pure Sand Greens

Piotr, a regional superintendent visited today.

It was nice to run into a superintendent that speaks English and seems to love what he’s doing. Got to banter with the guy, talk about construction, the problems with contractors and their shortcuts, golf course maintenance, his headaches, and had some laughs…a really nice guy.

The greens on Piotr’s second 9-holes were built with pure sand, but the builders used sand with too many fine particles...not enough larger stuff in the mix. Having a mix of some larger particles of sand is important for stabilization. His are so unstable he can't drive a sitting greens mower on them because they make light ruts.

At Sand Valley, by pure luck of the draw, we have about 60cm (2 feet) of finer, organic sand sitting directly atop a little more than a 30cm (a foot) of larger sand, all this capped with 30 cm of sandy topsoil. This combination of sand covers an area of about 10 football fields. We the two sands together (perhaps we also use 5cm of topsoil) and this combo should, in theory, make an excellent greens mix. It will also be cost effective.

The lab will run tests of this material, and tell us the optimal combination to achieve our goals of firm, fast and well draining putting greens.
