grapemanDoes the granular Sul-Po-Mag dissolve in water for you? How long does it take. I stirred for 5 minutes and still had plenty of grains undissolved.
Thanks for your input CC
Both K-Mag and Sul-Po-Mag are brand names for Langbeinite. In the case of Sul-Po-Mag they operate much like the Azomite company.
There is a company/product called Azomite which they sell under their own name. They also license a huge number of other companies to package it under their name like Down-To-Earth and the package has to have the word Azomite on it.
Sul-Po-Mag operates the same way. Your question confused me at first because I was not familiar with the granular form. I looked at K-Mag's website and they have both the granular as well as the powder (100% water soluble). The farm store that I go to carries the K-Mag label and it's only available in the powder form.
If it's pellitized (and not prilled) I'm thinking that you may want to look for the powder form. E. B. Stone has the Sul-Po-Mag brand in their product line. I do not know if it's powder or granular so you might want to fire off an email to find out.
Whatever potash product you may be looking at, the most important thing is that it is Sulfate of Potash Magnesia. Non-organic forms contain high levels of chlorine so that can't be good.
