The 0 inches is to the top of the cable or raceway used, so it would be have to be at least perfectly flush with the ground. Obviously you can go lower.
As mentioned with the other guy, 0 inches is the requirement to the top of the cable or raceway used. So at minimum, you’re allowed to be perfectly flush with the ground. Obviously you can and likely would go a little lower, although I don’t have any experience with trenching myself.

No, it means 50% of the cable must be submerged or buried. Little speed bumps all around.
