Hi all-

First time visiting and posting. I am removing some old, mostly dead, sod in order to lay some new sod. While removing the old sod, I noticed there is a bunch of white chalky dust and clods underneath, and on top, of certain areas of the old sod. What is this? Is there anything I need to know about it before laying the new sod? There are also a bunch of insects (earwig looking bugs) in the soil. Is that a problem? If so, what should I do about it?

I am getting ready to move out of state in a month or so, so I don't have a ton of time. Thanks very much for any assistance you can provide!
