There's more to a golf green than what appears on the surface -lesson from studio classroom

Let's imagine that you are standing on a beautiful golf green. The sun is shining, the sky is a bright blue, the birds are chirping in the nearby trees. It is a perfect day.

Now you look down at your feet. The grass is absolutely perfect too. Have you ever wondered how they get the grass on a golf green to be this perfect?

Is starts with a backhoe
A backhoe digs a nice big hole the size of the green. The hole might be 12 or 16 inches deep.
In the most advanced systems. this hole gets completely lined with plastic to create a gigantic waterproof tub. The bottom of this tub is covered with drainage pipes and several inches of gravel. A layer of special fabric covers the gravel. Then a foot or so of fine sand goes on top of the fabric and fills up the hole.
You can see what is happening. The grass is not growing in "dirt" at all. The green is very much like a hug flowerpot. The green's grass grows in sand with perfect drainage.

Location, location
Where you put the green is also important. It needs plenty of sunlight and good airflow over the green. On many golf. There are different varieties for nearly every climate and situation.

Keeping it up
Sand, perfect drainage and a good location eliminate a huge number of variables and problems. But now the grass it totally dependent on its keepers. There are no nutrients in the sand itself, so all the nutrients in the sand itself, so all the nutrients come from the people taking care of the green.
Once the green is established, you start in on maintenance. This includes daily mowing with a precision greens mower, watering, fertilizing, applying chemicals, aeration and general coddling.
