Aragonite and calcite are two minerals formed from calcium carbonate (CaCO. Lime (calcium oxide) is produced by heating limestone or seashells (calcium carbonate). The chemistry of calcium carbonate is similar to that of sodium carbonate and potassium carbonate except that calcium carbonate is not soluble in water.
Dolomitic lime is made from dolomite, a type of rock very similar to limestone except it also contains magnesium. In North Carolina, dolomite is found only in the mountains. Both types of lime provide calcium for plants, but dolomitic lime also supplies magnesium, a nutrient often low in soils in our area.olomitic lime is made from dolomite, a type of rock very similar to limestone except it also contains magnesium.
