Uneven land due to sinking

Yep. works fine.

It would help if you told us what kind of grass. Duh!

If you apply it so that it's not deep enough to kill the grass, yes. But typically when it's noticeable it's deep enough that you just bring in top soil then reseed.

Yes, it often kills much of the grass, but the weeds seem to grow first if you do not reseed.

That sounds good.

That seems bad, but maybe they can reseed.

They just annonced the opening of a natural cemetery nearby, no vault or casket/coffin needed. I'd prefer that.

But caskets have a lot of empty space inside them, maybe an average of 8 inches or more. Clearly, the law doesn't require a casket either. If there's no casket the earth above a body would sink gradually and not nearly as much.

This new cementery won't have anyone mowing the lawn, iiuc, but if it were an existing cemetery that does have a nice lawn, I wanted an idea of whether grass would keep growing after the earth sank but dirt was added.

Well, I don't know. Whatever kind the cemetery has.

You only get that problem if you use dirt with weed seeds in it.

Use loam with no weed seeds and it works fine without reseeding.

Makes more sense to cremate the corpses.

Harder to catch murderers who use poison tho.

You could cover bamboo with 6 inches of top soil and it would still grow through.

That takes an enormous amount of fuel, plus it fouls the air.

Kikuyu grass as well. That stuff is african jungle pretending to be lawn.

Its not that great.

Trivially avoided.

And it avoids massive great slabs of land stuffed with tens of thousands of rotting corpses and acres of wasted granite and marble tombstones and no need for lots of very expensive gardening.
