My plots are covered in deer do-do. Does this help the soil at all?

Steve it will add organic material to your soil. I don't think the volume that deer crap will make a real big difference, but it will help some.

I'd go start collecting it with a rake and a shovel and transporting to your plots....well OK, maybe not.

I wonder if I should just go back there when I have the urge and............. nevermind
