Hi all,


I would like to know about the wisdom of using greensand in potting mixes or
as a top dressing as a source of potassium and trace minerals. I read that
it weathers quickly making the various minerals easily available to plants.
I have used it in the vegetable garden for some years, especially on root
crops, with success that cannot be directly related to greensand. I think
that it is a good, "kind" source of potassium, but I am wondering to what
extent the trace elements are available.
