Mulch is said to draw nitrogen, but I'm not sure from where. Would it be only the top couple inches where the mulch is in contact?
I lightly topdress my mulch. I usually end up with layers, from mulching, then over time, adding compost, EWC, and mulching again, then maybe more compost. I figure that takes care of any N problem.
