I must be missing something.
Are you trying to amend the soil or increase the microorganisms population?
If trying to boost the microorganisms population add some molasses to feed them.
If trying to amend the soil, adding things like blood meal, bone meal, dolomitic lime, kelp meal, fish meal, etc is organic.
Today the word "organic" can be misleading. If it has ammonium nitrate, it's not orgaic. Take miracle grow "organic" for example. MOST of the ingredients are orgaic, but not all. You can be sure that if it says that it continuously feeds for 3 months, most likely not a true "organic", because of ammonium nitrate in it. A synthetic nitrogen compound.
If I understand correctly, a super soil will feed well beyond the 3 month period because of the microorganism culture continually breaking down the nutrient in the soil, in a more easily used form.
If you can use it in a hydroponic system, again it is not organic. Organic nutrient would clog the system of a hydroponic grow.
Worm castings , bat guano etc. are obviously organic. You can tell from the name where they came from. All natural sources.
If I said something that is incorrect, I am sure that someone such as WhiteWidowbb will correct me. I will tell you straight up that he knows far more than I.
There are certain standards for, let's say eggs, to be classified as "organic". Nothing but organic foods made from organic sources, no antibiotics, and such can be used on the chickens. There's pretty strict rules for you to say that your eggs are organic.
As far as I am aware, there's no such rules for soil. No rules, no penalties for misleading claims of "organic soil". Everyone thinks that all soil is "organic", but not the things that they might add are all "organic".
I too have seen "super soil" recipes using FFOF as the base for organic soils. So I can see where that might be confusing. They are right about ammonium nitrate not being organic though.
