tropical - your question here is the foundation of the discussion about the Book Gardening West of the Cascades. Apparently West of the Cascades means mineral depletion and the author of that book says you have to amend in order to grow vegetables. In addition he points out that amending with local mulch materials will also be low in the necessary minerals - sigh..... If your talking a mineral depletion a closed loop is going to be tough.
So like wyldthang said it's all going to depend on your area, your soil and it's issues.
I'd like to think that there is a natural solution for every problem. Maybe in my area it's hauling in seaweed.
Great Topic . . . .
