I use a compost tumbler like this.I take my old soil and re amend it then use it again. If you want to continue what your doing with less work look for a used concrete mixer to do the mixing for you.
I haven’t found one yet but I want to find a deal on a used one
If it ain't smoked or ingested it goes into the composter with the root balls to start the cycle over.
