Use of the Intercept Method in Determining the Calcite‐Dolomite Ratio for Rating Agricultural Limestones¹

Synopsis In one convenient analytical procedure, the intercept method gives the CaCO 3 equivalent, the proportion of calcite and dolomite and an estimate of the Ca and Mg content in a ground sample of limestone. Once the composition is determined, the sieve size or the minimum percent passing a sieve can be chosen.
