Tell an organic gardener that petroleum based fertilizers are 'organic' and I hope you have your running shoes on (and kevlar in some cases too)...
Maybe I'm 'old school' when I grow things, but I won't use fertilizers that came out of a science lab... My father taught me to garden back in the 70's... We had a in-ground pool put in and they put all the clay that came out of the hole all over the back yard... Within two years (of his 'organic' or natural gardening) we had a garden that did better than anyone else in our neighborhood.
I agree with AToE, the use of the term "organic" is silly, and a corruption of its original definition, when it is applied to gardening/farming/agriculture of any kind, including keeping of food animals, in today's usage. Organic, as noted by akueck, simply means comprised of compounds that contain carbon.
A much better term (in my opinion) for the kind of sustainable, natural-cycle gardening/farming that is done without the use of synthesized chemical adjuncts, is "natural" farming. Plain and Simple. Unambiguous. Either you allow the earth's natural processes to provide all the constituent ingredients that you use in your soil/nutrients/foods, or you use synthetics. No confusion.
BTW - Although I'm in no sense a "tree hugger," I see merit in pursuing natural, sustainable agricultural processes to the greatest extent possible. The relative health merits of natural techniques may or may not be real - there are still conflicting studies on much of that, with the exception of pesticides (most synthetic long half-life pesticides have been shown to do far more damage to the environment than they provide in short term good) - but the savings in energy ARE very real. Whenever you can take advantage of processes and chemical transformations that occur naturally in the environment then you don't have to waste energy in the synthesis of alternative compounds to perform similar functions. BTW - My Dad also practiced, and taught me, how to garden naturally. He got into it during the DDT scare of the early 60's, and as one result we ended up with lots of preying mantises on our property when I was growing up. I have to admit that, to a 10 year old boy, watching a mantis chew off the head of a just-caught grasshopper is a uniquely fascinating sight! ;D
To get this back on topic, now, I will add that I probably have more glass carboys than many of you; I've been collecting 'em since 1980, after all!
But I have recently invested in a couple of Better Bottles, and I'm convinced that they have their uses. I am also convinced that they don't pick up residues from my meads; when I simply rinse them in a percarbonate solution after use, they come out completely clean and residue (and aroma) free. I find that fascinating!
