Thank you very much for the explanation! I do know about iron fertiliser for plants and I have also experimented by planting plants that like the soil more acidic under a conifer tree or by putting the needles in the planting hole. even that seemed to have an effect.
I think @solominer has his hands full with his construction right now, but I really wanted to show you this soil. At least for me it is very unusual and it reminds me of mars. 😉
Your job is really very interesting! I am lookeng forward to more exciting posts from you. 😉
