A selective dissolution method for the simultaneous quantitation of calcite and dolomite in soils is proposed. This method, which can be used for soil dolomite contents as low as 0.1% (wt/wt), retains the attractive characteristics of simplicity and nonreliance on specialized or expensive equipment, while reducing interferences from noncarbonate sources of Ca, Mg, and alkalinity inherent in previous extractive methods. The expected relative inaccuracy of the proposed method is 3% of the “true” soil calcite or dolomite content if any Ca contributed by gypsum is accounted for independently and if the content of magnesian calcite in the soil is very low.
