I get this question all of the time so I figured I would show the process with photos. The J&D Turf crew added new infield mix to the existing infield at Huntington Park in Columbus, OH with the Head Groundskeeper, Wes Ganobcik, and his crew.
First, the addition of Field Saver 50 from the Natural Sand Company was applied with a topdresser. The FS 50 increased the medium sand content while also increasing the clay content and improving the SCR of the mix.
The next step is to blecavate/till the existing mix into the new mix. This is often the overlooked step in this process. It is time consuming, but necessary to ensure good soil bonding.
