What Is Dolomite Lime? Dolomitic lime is calcium magnesium carbonate. It has something like 20% calcium and 10% magnesium, but that can vary quite a lot. When you buy dolomite garden lime, it has been ground into granules that can be coarse or very fine, or it could be turned into a prill, a pellet, not necessary but easier to apply.
