Limestone: The Calcium Carbonate Chemical Sedimentary …
What is Limestone? "Limestone" means any rock formed mostly of calcium carbonate (CaCO 3), but to geologists, limestone is only one of several types of "carbonate rocks."These rocks are composed of more than 50% carbonate minerals, generally the minerals calcite (pure CaCO 3) or dolomite (calcium-magnesium carbonate, CaMg[CO …
Ground Limestone in Beef Cattle Diets

sulfate and magnesium ions tend to promote precipitation of aragonite instead of calcite. Aragonite eventually reverts to calcite, but it sometimes takes a long time; where sealed in sulfate-rich impermeable rocks, aragonite has in some cases been found in rocks even …
Should I use dolomitic or calcitic lime?
— Know the facts about the magnesium levels in your soil before deciding if you should use dolomitic lime. ... In some areas, the local and most economical source of agricultural lime is from a dolomitic limestone quarry. Calcitic lime may need to be trucked a longer distance, or vice versa. Either way, one source of lime may be cheaper than the ...

Dolomitic Lime vs. Calcitic Lime for Lawns
— But what exactly is the difference between dolomitic and calcitic limestone? These similar products actually have a strikingly different influence on your soil. 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 …
Dolostone (Limestone)

Ground limestone can have two different names that reflect the percentages of calcium to magnesium in the product. Dolomitic limestone is a combination of calcium (55-85%) to magnesium (45-15%) carbonates. Calcitic limestone is predominately calcium (95%) but still contains a small amount of magnesium (5%) carbonates.
AGRICULTURAL LIME VS. DOLOMITE LIME
— Often referred to as "aglime", agricultural lime is simply limestone that has been pulverized down to a fine particle size and introduced to acidic soil. Lime is selected because it contains such a high amount of calcium, which works to neutralize the soil's pH levels. ... If the magnesium level falls below the ideal ratio, or is less ...
