sand

Measure exact topdressing effect, and requirement, by checking total organic material by depth.

TL;DR: 1) Know the standard sand rate recommendations, which range from 6 to 11 mm per year at present 2) Measure the amount of sand you apply 3) Don’t apply the standard amount!

I’ve looked at soil organic matter (SOM) and OM246 test results for putting greens of different species. In the top 5 cm (that’s about 2 inches), there will be some SOM and there will also be undecomposed material.

A correspondent wrote with a question about sand topdressing amounts in relation to the turf GvX. “I’m hoping you’d be able to point me in the direction of finding something on sand inputs vs.

I’ve been following the total organic material (OM246) test results from the creeping bentgrass greens at Hazeltine National Golf Club with particular interest. Course superintendent Chris Tritabaugh has been measuring the sand application rate, the N application rate, and the aboveground growth (clipping volume).

A friend is in charge of a type of grass he hasn’t grown before. We went to look at the grass, and on the way to the golf course, he told me that someone had told him the grass didn’t need much sand topdressing.

Turfgrass managers deal with sand all the time. A sand has particles of various sizes, and taken together those particles make up the particle size distribution, which I showed examples of in this post.

I’ve been thinking about sand for a while now. At first I was thinking about quantities of sand (and organic matter); I’ve expanded that to also look at sand particle sizes.

I’ve updated the OM246 calculator to v2 with two substantial changes. One is an entirely new tab for unit conversions between different ways of expressing sand rates. I like mm. Others use kg/ha or tons/ha.
