Determination of Carbonate Concentrations in Calcareous
Introduction. Calcareous soils are those that have free calcium carbonate (CaCO 3) and pH values in the range of 7.0 to 8.3.If they are managed properly, calcareous soils can be used to grow most crops, excluding those requiring acidic growth media, such as blueberry.

Calcareous soils generally have a high carbonate content of the micromass, occurring in the form of micritic or microsparitic crystals. The b-fabric is crystallitic (Bullock et al., 1985), due to the bright small punctuations caused by the optical anisotropy of the small crystals.This fabric has also been termed K-fabric (Gile et al., 1965), crystic plasmic fabric (Brewer, 1964; Sehgal

Calcareous soils have often more than 15% CaCO 3 in the soil that may occur in various forms (powdery, nodules, crusts etc). Soils with high CaCO 3 belong to the Calcisols and related calcic subgroups of other soils. They are relatively widespread in the drier areas of the earth..

A calcareous soil is soil that has calcium carbonate (CaCO 3) in abundance.If a calcareous soil has hydrochloric acid added to it, the soil will effervesce and give off carbon dioxide and form bubbles because of the chemical reaction. Calcareous soils are most often formed from limestone or in dry environments where low rainfall prevents the soils from being leached
