The carbonate present in he soil is generally determined and reported as calcium carbonate (CaCO2)even though there may be dolomitic admixture and calcium replaced by magnesium.The calium carbonate is usually estimated by reacting with dilute hydrocloric acid.either standard or non-standard depending on the method.collecting the carbon-di-oxide in strong potaasium hydroxide and weighing.or by finding out the loss of carbon-di-oxide and computing for the calcium carbonate content.
