Amending Soils with Lime or Gypsum (NRCS 333) | AgBMPs

The most common material is ground limestone which is calcium/magnesium carbonates. Even though materials are not the same, they all follow the same process to neutralize soil acidity. Lime supplies a surplus of the basic cations Ca2+ and/or Mg2+ in a carbonated, hydroxide, or oxide form (CaCO3, MgCO3, CaOH, MgOH, CaO).

The Slow Carbon Cycle - NASA

Limestone, or its metamorphic cousin, marble, is rock made primarily of calcium carbonate. These rock types are often formed from the bodies of marine plants and animals, and their shells and skeletons can be preserved as fossils. Carbon locked up in limestone can be stored for millions—or even hundreds of millions—of years.

Flue-gas desulfurization - Wikipedia

SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2 (hydrated lime ...
