I have read in various places that you can mineralize your soil by baking it. It is the middle of Dacember here and freezing so the leaving it in the sun to dry method will not work very well. Does anyone have any advice for this method?
I have only ever done it in the sun. Took about a month or so and eventually became more sandy/silty as opposed to rich and organic. You may be able to do it in the oven on super low temp or something. I would just Google that
