Generally things get planted under the soil.  However, for root crops, that means a lot of digging.  This year I'm trying a new method:

  • First, till the ground - very shallow; 1-2 inches.
  • Then sprinkle a bit of rich soil atop the ground and arrange the root seed on the soil.

  • Then cover with adequate mulch

  • Finally top with more soil - it will eventually wash through the mulch, so expect to add a bit more before the shoots appear.

I'll see how it goes and keep posted on the progress.  You may have noticed that I planted a lot of potatoes in a small space.  I generally dig potatoes when they're new, and small.  You can always thin them later if you decide it's too dense.
