The death of organic foods?

Why You Can Now Kiss Organic Beef, Dairy and Many Vegetables Goodbye. Actually, this came from the NC links, but I'll highlight another one later.  I have to say that I haven't understood the whole organic market in the first place.  While we may not be able to use mined phosphorus and potash indefinitely in the future, I never understood why they couldn't be used in organic farming.  I can't imagine producing large amounts of milk and meat using feed raised without herbicides and commercial fertilizers.  Dairymen have enough trouble getting all their field work done on a daily basis while using herbicides, let alone trying to cultivate all their fields several times.
