Top 10 Companies in the Global Potassium Thiosulfate Fertilizer Market (2026): Market Leaders Powering Global Agriculture

MARKET INSIGHTS

Global potassium thiosulfate fertilizer market size was valued at USD 108.42 million in 2024. The market is projected to grow from USD 111.89 million in 2025 to USD 132.75 million by 2032, exhibiting a CAGR of 2.4% during the forecast period.

Potassium thiosulfate (KTS) is a highly soluble liquid fertilizer containing 25% potassium oxide (K2O) and 17% sulfur, commonly labeled as 0-0-25-17S in agricultural applications. This specialized fertilizer serves as both a potassium source and soil amendment, particularly beneficial for chloride‑sensitive crops while providing plant‑available sulfur. Its dual‑nutrient composition and compatibility with irrigation systems make it increasingly popular in precision agriculture practices.

The market growth is primarily driven by expanding adoption in high‑value cash crops, increasing sulfur deficiency in soils, and rising demand for efficient nutrient management solutions. However, price volatility of raw materials and competition from alternative potassium fertilizers present challenges. Recent industry developments include product innovations for foliar applications and strategic partnerships between manufacturers and agricultural cooperatives to enhance distribution networks in emerging markets.
