Planting in newly turned sod?

[TZ-OH6]

Well, the deed is done, but I thought I'd ask to see what to expect. Last minute garden area/expansion. I killed the grass with Roundup weeks ago and just turned the sod over, some was hilled up for mellons and squash, and some left flat for corn. So far I've put in small pre-started mellons, cucumbers, okra, and squash plus planted sweet corn. (if the transplanted seedlings die it is early enough to direct seed).


I am wondering if the decaying sod is going to affect growth by robbing nitrogen, or from physical barriers/air pockets (I did a pretty rough job due to tree roots), or if things are going to be more or less OK.
