North America Ammonium and Potassium Thiosulfate Market Size
The North American ammonium and potassium thiosulfate market size was valued at USD 133.66 billion in 2025 and is anticipated to reach a valuation of USD 141.84 billion in 2026 and USD 228.13 billion by 2034, growing at a CAGR of 6.12%, from 2026 to 2034.
Ammonium thiosulfate is a great source of nitrogen and sulfur. It contains 26% sulfur and 12% nitrogen, both of which are major components of plant proteins. Potassium Thiosulfate is an excellent source of potash and sulfur. It contains 17% sulfur and 25% potash. Potash is one of the most essential nutrients required by plants.
Both ammonium and potassium thiosulfate are used as fertilizers in a variety of crops. Moreover, both are compatible with each other when mixed in any ratio. They can be applied as starter fertilizers for corn and other small-seeded crops. They can be used on crops, ornamental shrubs, and golf courses through soil, foliar, and fertigation applications.
Growing demand for water-soluble macronutrient fertilizers, compatibility of ammonium and potassium thiosulfate fertilizers with many crop protection chemicals, and the wide range of applications of these products are driving the market growth. However, the availability of various alternatives to these fertilizers and the growing trend of organic agriculture are inhibiting the market growth.
