CALCITIC LIMESTONE -- A common material used for 'liming' soil that has an acid level that is too high. This type is most commonly used and contains calcium carbonate.
Dolomitic limestone contains calcium and magnesium carbonate, so it should be reserved for acidic soils low in magnesium. Most gardeners use calcitic limestone to lower the pH levels in soils, it supplies necessary calcium as well.
to raise the pH of soil is to add pulverized limestone to the soil. Limestone acts as a soil acid neutralizer and consists of either calcium and magnesium carbonate or calcium carbonate. These are called dolomitic limestone and calcitic limestone ...
LIMESTONE -- Sometimes used when 'liming' soil that has an acid pH level that is too high. As it contains calcium and magnesium carbonate it should be used only with soils that are also deficient in magnesium as well. (See also Calcitic Limestone) ...
Calcitic lime, also called aglime, has a neutralizing value between 85-100 percent. In addition to neutralizing soil acidity, calcitic limestone supplies calcium, an essential element for plant growth.
