What are the main advantages of Calcium Thiosulfate in agriculture?
 It provides three key benefits: supplies available calcium and sulfur, improves saline-alkali soil by replacing sodium ions, and effectively prevents fruit cracking while enhancing fruit quality.
How does it help with selenium contamination in soil?
The thiosulfate radical can reduce plant-unavailable selenites to elemental selenium or other insoluble forms, reducing selenium's bioavailability and transfer into the food chain.
What is the recommended storage method?
Store in a cool, dry, well-ventilated area away from fire and heat sources. We provide 200L drums and IBC totes for convenient storage and handling.
