OG, perhaps you didn't notice, but this thread is two years old, and I don't recall seeing any recent posts from buoana boy in some time. So don't be surprised if there's no response from him.
That aside, your comments re: rotation seem grossly oversimplified. They certainly overstate the case.
In theory, crop rotation is practiced for two reasons: to prevent depletion of nutrients, and to deter pests and disease. The first is totally in disrepute. Whether you are organic or use conventional chemical farming, it doesn't truly apply---and likely never did. Either way you are replacing nutrients. The only difference between you and a synthetic chemical proponent is that you are creating healthy soil and the other guy isn't. But both of you are replacing depleted nutrients on an on-going basis.
Pest and disease prevention only makes sense if 1. You have an incredible amount of land (not true for the typical diverse organic grower), or can so arrange your crops that neither the original species nor any relative is within migration distance of an infection---difficult with soil-borne organisims, nearly impossible with air-borne ones.
Let's say you had a problem with tomatoes in one area, and have enough space to safely move them out of the way (which can mean not planting them downwind, as well as planting them far away). The list of things you cannot plant in the original area (or even close to it) includes peppers, eggplant, potatoes, and, to stretch a point, tobacco. Disease bacteria do not just fade away. Self-sanitation can take as much as three or four years; three or four years in which you cannot return the original or its relatives to that location. So the question becomes, do you have enough land to grow them far enough away? Or do you drop them altogether? And, if the latter, what do you replace them with that is marketable?
On the other hand, if you've never had a significant infection, there's no reason not to grow tomatoes in the same ground, year after year.
I'm not suggesting that crop rotation is totally ineffective. But it's not the panacea many growers have been led to believe. And the mechanics of it can drive you to drink.
