"Kevin" expounded:

I have an area of garden that has been covered in bark chips. I now wish to
level and raise it slightly with a layer of top soil prior to seeding as a
lawn.

Will it be OK to cover the bark chippings?

Advice please?

Are the chips fresh? If they've weathered for a year or two, I
wouldn't worry about nitrogen use. Just cover them with a good thick
layer of topsoil and forget about them.
