Q & A

Q1. Which are the predominant factors that affect the price of calcium thiosulfate?

Many factors affect the price of calcium thiosulfate. First is the purity level. Higher purity levels often come with a higher price tag. This is primarily due to the complex and lengthy production processes required. The formulation type also affects the price of the product. Liquid formulations are usually pricier than solid or powder forms. Buyers also have to factor in transportation costs, which can add to the overall cost of the product, especially if the product has to be ferried over long distances.

Q2. What happens when one mixes calcium thiosulfate with calcium nitrate?

Mixing calcium thiosulfate with calcium nitrate leads to precipitation. In simple terms, calcium thiosulfate contains thiosulfate ions, while calcium nitrate incorporates nitrate ions. When the two solutions are meshed, they produce calcium sulfate. This is an insoluble compound that will precipitate out of the mixture and settle at the bottom. The precipitation not only reduces the effectiveness of the two compounds but also clogs spraying and irrigation equipment.

Q3. Can calcium thiosulfate be coupled with other liquid fertilizers?

Yes, liquid calcium thiosulfate can be coupled with other liquid fertilizers. That is, of course, when the other fertilizers are compatible with it. Many farmers combine calcium thiosulfate with nitrogen-based fertilizers like urea or ammonium sulfate. This enhances the effectiveness of the fertilizer.
