Interactions of calcium sulfite with soils and plants
CaSO3 is a by-product formed by several of the processes used for scrubbing SO2 from flue gas produced by coal-burning power generators. Using CaSO3 to improve the calcium status of acid soils would be a beneficial alternative to disposal in landfills. CaSO3 has biocidal properties and is used as a disinfectant and food and drink preservative. It is important to evaluate under what …
