The problem with organic fertilizers is a lot of the synthetic fertilizer use is still happening, just upstream of the organic farm. At best they're using things like manure and food processing industry byproducts that otherwise don't have an outlet (but which are overwhelmingly derived from conventionally grown crops); at worst (and this is a non-trivial amount of organic fertilizer) they're applying conventionally grown and otherwise edible soybeans.
Let's not forget that in the us steel slag and its derivatives are considered organic fertilizer. Theyre less popular with the decline of the steel industry. Also dried blood, sorry vegans.
State regulations have gotten better about heavy industry wastes due to all the soils getting contaminated with heavy metals, but yeah, a ton of organic produce is not technically vegan due to the high prevalence of slaughterhouse residues and fish emulsions in organic production.
