<v Speaker 1>works dot Com where smart happens. I am Marshall Brain

0:00:28.640 --> 0:00:32.040
<v Speaker 1>with today's question, how can the grass on the greens

0:00:32.080 --> 0:00:36.320
<v Speaker 1>at a golf course be so absolutely perfect? If you

0:00:36.360 --> 0:00:38.880
<v Speaker 1>have ever really looked at the grass on a well

0:00:38.960 --> 0:00:43.040
<v Speaker 1>maintained golf green, it is absolutely amazing. It is a

0:00:43.080 --> 0:00:46.400
<v Speaker 1>flawless surface made out of plants. To make it this

0:00:46.520 --> 0:00:49.880
<v Speaker 1>perfect takes a lot of work. The work starts by

0:00:49.920 --> 0:00:53.920
<v Speaker 1>creating what is practically a hydroponic growing system for the grass.

0:00:54.360 --> 0:00:57.920
<v Speaker 1>When constructing the green, a bulldozer creates a twelve inch

0:00:58.000 --> 0:01:00.840
<v Speaker 1>to sixteen inch deep hole this side of the green.

0:01:01.360 --> 0:01:04.919
<v Speaker 1>In the most advanced systems, this whole is completely lined

0:01:04.959 --> 0:01:08.600
<v Speaker 1>with plastic, and then gravel and drainage pipes are added

0:01:08.720 --> 0:01:12.840
<v Speaker 1>top by sand. The green's grass grows in a sterile

0:01:12.959 --> 0:01:17.120
<v Speaker 1>sand medium with perfect drainage The surface is contoured to

0:01:17.120 --> 0:01:20.520
<v Speaker 1>allow perfect runoff as well, so there's no puddling when

0:01:20.520 --> 0:01:23.840
<v Speaker 1>it rains. Where you put the green is also important.

0:01:24.120 --> 0:01:27.440
<v Speaker 1>It needs plenty of sunlight, preferably full sunlight with no

0:01:27.600 --> 0:01:31.680
<v Speaker 1>surrounding trees, and good airflow over the green. Sometimes you'll

0:01:31.720 --> 0:01:34.440
<v Speaker 1>see fans placed around a green to keep that air

0:01:34.520 --> 0:01:39.280
<v Speaker 1>flow going. Then you choose perfect grass. Grass that's ideally

0:01:39.360 --> 0:01:43.120
<v Speaker 1>suited to your climate. A sterile sand medium, and a

0:01:43.160 --> 0:01:46.399
<v Speaker 1>good location controls for a huge number of variables. But

0:01:46.480 --> 0:01:49.360
<v Speaker 1>now the grass is totally dependent on its keepers for

0:01:49.520 --> 0:01:52.960
<v Speaker 1>life support. That means the grass needs a steady diet

0:01:53.000 --> 0:01:55.840
<v Speaker 1>of water and nutrients to keep it alive. To this

0:01:56.000 --> 0:01:59.559
<v Speaker 1>mix is added a variety of herbicides to kill weeds

0:01:59.640 --> 0:02:03.440
<v Speaker 1>that try to move in, pesticides to control inchect damage,

0:02:03.520 --> 0:02:07.920
<v Speaker 1>and fungicides to control disease and help keep the grass perfect.

0:02:08.520 --> 0:02:11.960
<v Speaker 1>Once the green is established, you started on maintenance. This

0:02:12.080 --> 0:02:16.840
<v Speaker 1>includes daily mowing with a precision greens mower, watering, fertilizing,

0:02:16.840 --> 0:02:20.960
<v Speaker 1>applying chemicals, aerating, and general coddling. If you were willing

0:02:21.000 --> 0:02:23.560
<v Speaker 1>to do all of this, you too could have a

0:02:23.600 --> 0:02:27.560
<v Speaker 1>golf green in your front yard. For more on this
