Microbes are not the same as those inputs mate. Dont worry we can help you understand.
So Azomite is a form of mineral rock dust, may be volcanic, anyway its all those things people call micros and trace elements, examples being Calcium, Magnesium, Copper, Zinc. Minerals are really bits of metals for example, which we find in rocks, clays, in sand particles etc.
Microbes are living organisms, they feed from the minerals in Azomite for example, when they feed they convert what is a non plant ready mineral element such as magnesium hanging about in soils, in to magnesium ions, or magnesium with an amino acid, once its an ion, it can be taking up via the roots of our plants.
Now blood, bone, kelp, crustacean meal etc and worm castings, these are all organic inputs, these materials contains all the growth elements our plants need, eg Nitrogen, Phosphates, Potassium, but we need microbes to converts this big material, in to tiny bits a plant can manage.
Worm casts are an exception in your list being slightly different in that they are already plant active and they also contain millions of microbes that have and are busy converting minerals and organics, in to food for themselves and plants.
In the wild, we have microbes that have evolved to live in local conditions with local flora. We can collect this indigenous microbes to use in our own gardens, but this takes some skill and knowledge to collect good microbes and not bad, its not difficult to learn however
