I haven't done any soil testing so far. Every test costs $80. I do sheet mulching (because of the lack of soil) and I really have no clue what is in the soil.
I would rather pay for a decent soil tyest kit, because I need a huge number of samples as every spot is different.
Actually soil testing could be a small business idea - but then I don't know you might have to spend a lot!
