Is it Possible to Overlime With Dolomite?
Yes. Dolomite is a liming material, and any liming material has the potential to raise soil pH to a level where negative plant response is obtained. For example, liming blueberry plants or bahiagrass to pH 6.8 is considered overliming because those species grow better in soil of lower pH. Because the equilibrium pH of dolomite is lower than that of calcite and other aglime materials, there is an incorrect belief that it is impossible to overlime with dolomite. Remember that lime is applied to soil in order to benefit the plants that grow there, not to benefit the soil per se. Overliming refers to the effect on plants, not soil.
