Limestone Sources and Crop and Soil Responses

2020-10-13 · crushed limestone is the most common material used to neutralize soil acidity. Depending upon the quarry, limestone may be calcitic, dominated by calcium (Ca) carbonate, or dolomitic, possessing varying portions of Ca and magnesium (Mg) carbonate. Without exposure to soil acidity, very little limestone dissolves in the soil.

Materials

2015-5-5 · limestone usually contains CaCO 3 and some impurities. However, some limestones will also include MgCO 3. Ground limestones make up the majority of lime that is sold in NY. Ground limestone with less than 1-6% Mg is called "calcitic limestone". If the limestone has 6% Mg or more it is called "Dolomitic Limestone".
