"Organic" is just a word, and like many words has multiple meanings depending on context. In the context of farming / food production it means primarily not using inorganic NPK fertilizer, so it makes perfect sense that way; organic fertilizer (compost, manure) as opposed to inorganic fertilizer (for example Urea, Phosphoros Pentoxide, Potassium Chloride). So, sure, all food is made of organic matter, but not all of it is grown with exclusively organic fertilizer.

On the other hand, meeting the legal requirements to call your crops "organic" doesn't guarantee that they are of higher quality or that the farming methods are much more sustainable.
