That is a a similar process to what I used to do with my veggie garden, however with some differences. I'd till the soil after harvest and cover it with a layer of compost, moisten and then cover with black plastic. I used re-cycled tarps that I use for covering the hay. We don't get the intense heat like they do in California, so the black absorbs the heat and it gets really hot under there. I would switch between two areas and plant every other year. Now I have stolen so much of my area for the veggie garden that I don't have space there to continue to do it that way. In the fall the heat isn't intense enough to solarize, so the worms and insects will break down the organic material. By the time I was ready to uncover and plant, it was all mixed in and I could just pull back the tarps and plant. Now I do a modified version of that. I put down the tarps and cut holes into it and plant. I use them more as a mulch then for solarizing. Of course I can't cover the ground where I'm planting seeds, only where I plant things like tomatoes, peppers, eggplant, and the like. Here's what that looks like in my tomato patch.
Doing it this way doesn't solarze the soil, but merely acts as a mulch. I never used to have any issues with tomato blight when I did it the old way, Doing it this way it's come back. I've solarized a new spot in a different area now to start some kind of new garden, Most likely it will be for veggies, as I will need more and more space for iris seedlings. (And of course my never ending wish list!) Plus now I've started to have a quite a few Dahlias that I plant there too.
