I'm not sure there is any evidence to support the claims that organic food can be stored for longer, contains more nutrients or is healthier. Tastier is a matter of perspective, but again another claim lacking support. All foods; plant, fungal or animal based, are chemically derived. I think the point you are trying to make, is that organic farming is more holistic, and less dependent on artificial supplementation. It is important to use the right vocabulary or we are debating different things.
Before continuing any further, it might be useful if you defined your intention of the word organic, that way we can systematically assess its efficiency and plausibility.
