Function:
Dolomite is a carbonate mineral comprised of magnesium and calcium. Dolomite isn't a fertilizer, but a soil conditioner that's used to "sweeten" acidic soils and make them more alkaline. Because dolomite is particularly slow-acting, it must be added to the soil well in advance of planting to gain the desired benefit. Powdered dolomite lime can also be mixed into a nutrient rich fertilizer blend so that you can enrich the soil and correct its pH at the same time..
