The calcium carbonate equivalent (CCE) of agricultural lime is directly related to its purity. Pure calcite, which is 100 percent calcium carbonate (CaCO 3), has a CCE value of 100; whereas pure dolomite (CaCO 3 •MgCO 3) has a CCE of 108. The CCE and chemical composition of several common materials are shown in the follow-ing table.

Oct 12, 2018 · As lime (dolomitic and/or calcitic) is a mined resource, it's quality/purity varies. Calcitic lime (most products contain 30-35%Ca by bag weight) cannot contain more than 6% Mg and still be labeled calcitic lime. Greater than 6% and it is classified as dolomitic (commonly, dolomitic limes will be about 11% Mg and 21% Ca by bag weight).

Calcitic Lime vs Dolomite Lime: Which Should You Use?

Calcitic lime has long been the preferred treatment for acidic soil. A thorough application of pulverized limestone tilled into the soil raises the pH to a neutral level, increasing crop yields and improving overall soil health. The main "ingredient" in calcitic lime is calcium carbonate, which is why many people ask if calcium carbonate is the same a limestone. It counteracts the acidification of field soil.
