How does it smell ?
Alfa is Nitrogen heavy and anaerobicly provokable.
In the absence of oxygen, lactic acid is produced. This is how ranchers make silage.
What is the ambient temperature, where the soil is stored ?
There is an exothermic reaction that needs to occur but it is facilitated by reasonable ambient temperatures,,,, meaning that while I continue to mix my soil outdoors all winter( below freezing) , there is no action happening.
I do not understand all of the chemistry and I am certainly no authority on the topic. However given the same situation this is what I would do.
Spread all of that soil out on a warm surface , and let it get bone dry.
Completely saturate with water , and dry cycle again.
In time, try a germination test.
Sprinkle (ideally cannabis) seed across the media. Any seed would work. Bean and Legume seed are inexpensive, Peas would work also- they would fix up N at the same time.
If they grow you are good to go. If they burn up, you need to keep cycling~or dilute.
Don't be discouraged , this is probably a case of bad timing , not bad product
