Approach Solution -2
Breaking down the mineral formula: Dolomite's chemical formula is CaMg(CO3)2, a double carbonate of calcium and magnesium.
Decomposing the formula shows exactly two metal cations present, calcium and magnesium, bonded with carbonate; there is no iron or sulphur anywhere in the structure.
So when dolomite is applied as a liming material, it supplies only calcium and magnesium to the soil.
