No, in nature certain nutrients are almost always inorganic when available to the plant and must be inorganic to be available to the plant. Oh these classes are eye opening!

For example potassium.

TV, the media, marketing and advertising campaigns from food companies, have sold us on these "organic" concepts that are incorrect except from a fundamentally philosophical perspective that promotes sustainability. I'm not sure why I didn't realize that before... I kinda just bought into it as well, but that's what life is for live and learn!

Hmmmm.....I wonder where all that K in Maxicrop comes from? 1-0-4

I did say IMHO.
