Answer: I'm not a golfer, so I don't know of these containers on the golf course. I'd guess that it's a mix of grass seed and dried compost that you can spread in the divot. Once it rains or they water, that will start the germination process and the compost helps with fertility and "filling in" the hole. I suppose you can do the same in your yard. Just choose a grass variety that's appropriate for your law. Fescues for the shade and bluegrass of ryegrass for the sun. You might want to have an iron rake to scratch the soil before seeding. Then just "chip" (couldn't resist the pun) away at the project.
