Not a bad start, but some questions are definitely coming up for me.
Is this also his pile for food scraps? Is he dampening the other materials? How long does he add material to this hole?
I guess if you have enough space you can just keep digging holes and burying, but with one big compost heap, he can keep it simple and get better results.
