Calcium Blog What Is Calcium Thiosulfate Used For

What is Calcium Thiosulfate?

Calcium thiosulfate is a chemical compound that is commonly used as a soil amendment and fertilizer. It is made up of calcium, sulfur, and oxygen, and is often used to provide plants with the necessary nutrients they need to grow and thrive.

Why is Chemical Compatibility Important?

When using calcium thiosulfate, it is important to consider its chemical compatibility with other substances. This is because certain substances may react with calcium thiosulfate, which can cause a range of issues such as reduced efficacy, corrosion, or even damage to equipment.

Factors that Affect Chemical Compatibility

There are several factors that can affect the chemical compatibility of calcium thiosulfate. These include temperature, pH levels, concentration, and the presence of other chemicals or substances.

Compatibility with Fertilizers and Pesticides

Calcium thiosulfate is generally compatible with most fertilizers and pesticides. However, it is important to check the label of each product to ensure that they can be safely mixed together without causing any adverse reactions.

Compatibility with Water

Calcium thiosulfate is highly soluble in water, which makes it easy to mix and apply. However, it is important to ensure that the water used is clean and free from any contaminants, as this can affect the chemical compatibility of the solution.

Compatibility with Metals

Calcium thiosulfate is generally not corrosive to most metals. However, it is important to avoid mixing it with certain metals such as aluminum and magnesium, which can react with the compound and cause damage.

Compatibility with Plastics

Calcium thiosulfate is generally safe to use with most plastics, including PVC and polyethylene. However, it is important to avoid using it with polycarbonate, as this can cause the plastic to become brittle and crack.


In conclusion, understanding the chemical compatibility of calcium thiosulfate is important for ensuring its efficacy and safety. By taking the time to consider the factors that can affect compatibility, you can ensure that you are using the compound safely and effectively to provide your plants with the necessary nutrients they need to thrive.
