For a fact i know it produces nutrients which are returned to the soil and used by plant and also produces carbon dioxide.... I think
Thermal Decomposition is the name of the reaction to produce quicklime from limestone.
Decomposition reaction - catabolism
decomposition
2LiClO3 --> 2LiCl + 3O2
Grinding quarts crystals down to produce sand is an example of decomposition.
Mg(OH)2 --> MgO + H2O
Ba(ClO3)2 --> BaCl2 + 3O2
Decomposition
Ni(ClO3)2 = NiCl2 + 3O2
They produce protons, which limit decomposition and CO2 production in peat bogs.
waste removal
Pb(OH)2 --> PbO + H2O
