oddball question on alternating strips of dark and light green

[Syrinx]

A lot of football fields, including the one at Bryant-Denny Stadium, have fields that alternate every five yards twixt light green and dark green. How do they do that?

Do they use two different types of grass? Or do they just give the darker sections a more nitrogen-rich fertilizer?

I admit it's not really an important question, just something I wonder about when I have too much time on my hands.

1. I think it is how the mow the grass actually

Baseball fields have had the same kind of thing going on with patterns in the grass.

2. Hmm

Didn't think of that. Thanks for giving me something else to think about in my idle hours. ;)

3. LOL

If I could clear my brain of superfluous thoughts....

4. Sitting at the Big House last Saturday, I wondered the same thing

I don't think we have real grass anymore, though, so the mowing direction wouldn't be relevant.

5. They weight the lawnmowers and press the grass

while cutting it in different directions. If you were to view the grass from the other side of the field, the colors would appear difference depending on whcih way the light hits it and your direction to the cut. It is pretty cool and I do it on my lawn at home sometimes.
