Alkali soil Wikipedia

Alkali soil. Alkali, or Alkaline, soils are clay soils with high pH (> ), a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer at to 1 metre depth. Alkali soils owe their unfavorable physicochemical properties mainly to the dominating presence of sodium carbonate,...

4. SODIC SOILS AND THEIR MANAGEMENT

Soil amendments are materials, such as gypsum or calcium chloride, that directly supply soluble calcium for the replacement of exchangeable sodium, or other substances, such as sulphuric acid and sulphur, that indirectly through chemical or biological action, make the relatively insoluble calcium carbonate commonly found in sodic soils, available for replacement of sodium.

Calcium carbonate Essential Chemical Industry

Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.

Mud contamination

Calciumions contamination. For example, sodium carbonate (soda ash) is used if the source is gypsum or anhydrite. Sodium bicarbonate is the preferred treatment if the calcium ion is from lime or cement. If treatment becomes economically unacceptable, break over to a mud system, such as gypsum mud or lime mud, that can tolerate the contaminant.
