Calcareous soil

A calcareous soil is soil that has calcium carbonate (CaCO₃) 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 of carbonates. Calcareous soils frequently cause nutrient deficiencies for many plants.

calcareous soil Soil that contains enough free calcium carbonate to effervesce visibly, releasing carbon-dioxide gas, when treated with cold 0.1 N hydrochloric acid, and which could also be regarded as a basic or alkaline soil.
