    reported in a soil test is in tons of pure calcium carbonate, not tons of any liming material. The TNV is the percentage of the limestone capable of neutralizing an acid and is expressed as CCE. If a limestone has a TNV of 80 percent it means that 1 pound of it will neutralize the same amount of acid as 0.8 pound of pure calcium carbonate.

    Nov 17, 2014 The CCE value of a limestone is obtained directly by dissolving a sample of the material in an acid. However, aglime analysis is often reported in different ways, such as calcium oxide (CaO) and magnesium oxide (MgO) or as calcium carbonate (CaCO 3) and magnesium carbonate (MgCO 3). You can easily calculate the CCE value of an aglime material ...

    ENM is calculated by multiplying the percent ELM as shown previously by 800 which is a constant that refers to the amount of effective calcium in one ton of pure lime. For example a limestone with an ELM percentage of 54% would have an ELM of 1080 lbs. per ton but would have an ENM value of 432 lbs. per ton (800 x 0.54=432).
