Calcitic Lime vs. Dolomite Lime - Baker Lime

The primary difference lies in the use of magnesium: Dolomite lime contains large amounts of magnesium along with calcium carbonate while calcitic lime only contains calcium carbonate. Magnesium is an important mineral for plant health. And if soil needs magnesium, wouldn't it be best to just use dolomite lime all the time, just in case?
