What is the difference between synthetic and organic fertilizers?

[Smokin Moose]

Synthetic fertilizers are made from chemicals such as sulfuric acid and hydrochloric acid.

Organic fertilizers are composed of natural materials.

aspirin is an acid also. It begins as bark of a particular tree. Processed to be consumable by humans. Is this an organic product or a chemical one? Is a processed product a chemical? I don't think so. Take milk. the cow has to eat organically, the pasture has 2 b organic, then certified. I think a compost tea fort the garden is a good nute. How does one go about getting organic potassium w/o buying a product that says omri approved? you usually buy some anti caking ingredients in your organics maybe a food starch modified or something.
