Sorry I don't have any input about the soil analysis. This was one of the few threads I found mentioning Peganum Harmala. May I ask, is there a specific reason you included it in your list?
I am interested in growing it for its use as a natural dye. However I've read that it can be very invasive in certain conditions and dangerously toxic to grazing animals. Apparently they normally avoid it because of its bitter taste, but I live on a Mediterranean island with thousands of freely grazing sheep and goats, and pasture can be scarce in dry summers. So, I am hesitant about growing it.
Also I just read a study saying it has allelopathic effects on the germination of wheat and purslane seeds (possibly on other plants as well).
