The new short game area greens will be grown on a mixture of 80% sand, 15% compost and 5% peat. The new greens (5-8) are grown on a similar mixture, while #2 & #16 greens are grown on a sand/peat mixture. The remaining greens are "push up" or native soil greens. "Push up" simply means that when the greens were constructed they pushed up the existing topsoil and shaped it into a green.
Below is a picture of the blending machine used to make our 80/15/5 mixture.
The compost is used in our greens mix as a source of organic matter and nutrients. The compost also allows the new greens to have a similar composition to our existing push up greens. For many years now, the greens have been topdressed with straight sand and after taking a sample of the top 2" of the profile recommendations were made for a sand/compost mixture.
