Sorry, I didn't document things . . . I tend to be great at coming up with ideas/ plans, very bad a following through on them!
I do remember that we had mountains of tomatoes in 2014. However, I now don't think sheet mulching is an idea way to grow standard vegetables on a large scale. It didn't keep the bindweed out, just made the bindweed harder to deal with. It tended to dry out. Most vegetables are ruderal species adapted to disturbed mineral soil. It was actually more work that tilling; spreading a foot of wood chips, cardboard, and manure over a quarter acre garden is back breaking, and the soil underneath didn't fluff up like it was supposed to.
I think that initial tillage followed by crimped cover crops would be a good low-till system for large scale vegetables. But I have not tried it yet, just looked at the projects of others.
