Since limestone raises the pH (or alkalinity) of soil, and since our desert soils are already highly alkaline (8.0 - 8.5), it's not recommended to add more limestone to our soils. Dolomitic limestone does contain a trace of magnesium, but so do many balanced fertilizers and magnesium deficiencies are not terribly common here. I'm not sure of brands available. You might want to check with a full-service nursery. If they don't offer it, they can probably order from the supplier.
