Calcium sulfite is known as a calcium salt that serves as a preservative which is implemented in large food industries. Calcium sulfite is used mostly in beverages such as cider, fruit juices, wine, and canned fruits, as well as in vegetables. Calcium sulfate is also a great natural fertilizer for agricultural use, its use makes the soils progressively renew and does not deteriorate so easily with the use of unlimited fertilizers and the excess of rotating crops.
It is implemented directly in any type of soil, allowing the improvement of its moisture status and physicochemical qualities of the soil. Calcium sulphite transfers salts and corrects calcium deficiency in crops, prevents plants from filling with parasites and fungi through their roots, thus having a very healthy plant. It does not allow the fall of the flowers, the wrinkling of the leaves and the fall of buds and fruits, the yellowing of the coffee fruit, thus strengthening the structure of the stem in plants.
Calcium sulphite is a white powder, it is not permanent and reacts with oxygen to give rise to calcium sulphate. Like other metal sulphites, they reactivate with acid to give rise to sulfur dioxide which is a highly irritating gas in a gaseous representation and in water. It is almost insoluble in water, but the opposite happens in ethanol, since if it dissolves in it, in wine it usually dissolves little by little resulting in SO.
Calcium sulfate is used in different plantations such as in the cultivation of coffee, banana, rice, potato, fruit trees, cotton, cocoa among others. It is also recommended to apply in organic crops in jungles and Costa Sierra. The appropriate dose is 500 to 1000 kg / ha, but everything will depend a lot on the analyzes of the crops and the soils to be fertilized. It could be applied only in lands where there is enough organic matter or that is protected by a large nitrogen germ such as island guano, urea, among others.
