I highly recommend the kitchen sink method.
I have been working and amending my soil for 10 years now
It all started here, in an aquarium.

includes
Leonardite, Aragonite, humalite , turface red clay, Peat, vermiculite, hydroton, river sand, coal, schintered carbon, firepit ash, creek-muck, blackearth topsoil,,,
Root balls and household compost goes into the Bunny pile.
Timothy, greens, and stable sweepings are constantly turned in.
If I keep a layer of leaf litter on this pile, I can actually, honestly, literally hear the night crawlers working through it at night.
When I first heard it I thought it was mice. The worms crinkle around in the leaves and it sounds like the softest mist of rain. Sounds like plastic shopping bags.

From there it goes into the green pea beds. After a season , I cut in coco, and it is ready for duty.
