Dolomitic limestone, or dolomite (MgCO 3 +CaCO 3), is also a commonly used source. Dolomite usually costs a little more than calcitic limestone and changes the soil pH more slowly, but it has the advantage of containing Mg as well as Ca. Together, calcitic limestone and dolomitic limestone account for more than 90 percent of the lime used in ...

Dolomite lime reduces soil acidity at a slower rate than calcite lime (a few months vs. a few weeks) and may have the side effect of hardening clay soils, which further inhibits plant growth. You should only apply dolomite lime if your soil is magnesium-deficient, which is defined as a 6:1 ratio of calcium to magnesium, based on a soil test. ...
