I had a soil test done at Logan labs and paid for the Agronomist advice. He recommended something called K-Mag. This is for an orchard I am developing (1/2 acre).
I know Sul-Po-Mag also goes under may different names such as 0-0-22, also known as (aka) langbeinite, aka sulfate of potash-magnesia? This is basically 22% soluble potash, 22% sulfur and 11% magnesium.
It seems to be a mined material (not sure) but I am having trouble getting any
local nursery or Farmer Co-op to locate.
I live in North Alabama and could use a couple of 50 lb bags.
Any recommendations or alternatives?
