The only source of magnesium I know of to correct soil deficiencies is epsom salts. Is there any other compound out there and where can I get it? I'd rather apply magnesium in it's purest form since I have already done my soil amendment calculations.

Domomitic lime has alot of MG in it but will also raise ph

Thanks Al. My pH requires no adjustment and I've made my calculations based on the current pH. I just couldn't find an easier way to add magnesium in its purest form other than epsom salts.

Whats wrong with epsom salt? Also know as Magnesium Sulfate
MGSO4 + 7H20. Which is a very soluble and available to the plant. To many people associate the word salt with something bad. A salt is simply an ionic compound that results from the nuetralization reacton of an acid and a base. Calcium Carbonate (Cation)Ca2+ +(Anion)C032- is a salt.

Only other readily available form is Calcium Magnesium Carbonate which is Dolomitic Lime

There is nothing wrong with epsom salt Shannon. It is easily handled but is only 9.8% magnesium and, if you grow a number of plants, a lot of it can be required.

Thanks everyone for your responses. I did some major digging and located a product produced in Canada which is 36% Mg and contains 6% sulfur as well. The sulfur should be of little consequence based on my soil analyses. I am currently awaiting pricing and availability information. The product is called ProMag and produced by nu-gro. It'll sure save a lot of product handling and spreading if it's competitively priced with epsom salts.

Promag (If I looked at the right product) is a mixture of magnesium sulfate and magnesium oxide. Still have some epsom salts in there, plus the anion of a portion is the oxygen.

That will surely affect your PH...
