Noticed this while out cutting some leaners this morning. Sand channel on left quad-tine core, channel on right solid-tine. #issolidbetter? pic.twitter.com/OiGXBFjOZ5— Rob Steger (@SaginawCCturf) February 23, 2017
And then this rely:
@TheFortressTurf Tried solid tines for the first time last fall, incorporated 30% more sand into the profile than we usually do. 3/4"— Rob Steger (@SaginawCCturf) February 23, 2017
This got me thinking about what I have noticed on my course. For the past few years we haven't been pulling a core and I also noticed that we were able to get about 30% more sand into our greens at aeration time but never really though much of it as it relates to solid vs core aeration.
I think that when we core, it is difficult to get the entire plug removed. This leaves some of the holes still partially filled with soil/sand and reduces the amount of sand we can get into the hole. Getting a good core is dependant on a lot of factors. Getting a good tine penetration is dependent on a lot less.
When we solid tine, we get a more consistent depth because we are not leaving behind any material, we are simply smashing the tine in and spreading the soil apart. We can then get a more reliable hole depth, and therefore, more sand into our profile.
