The potassium sulfate market is projected to grow from USD 5.4 billion in 2025 to USD 8.7 billion by 2035, at a CAGR of 4.9%.

NEWARK, DE, UNITED STATES, November 14, 2025 /EINPresswire.com/ -- The global potassium sulfate market is set to surge from an estimated USD 5.4 billion in 2025 to USD 8.7 billion by 2035, registering a total growth of 61.1% and a CAGR of 4.9% over the forecast period, according to FMI’s latest market analysis. This growth is driven by the rising adoption of chloride-free specialty fertilizers, expanding protected horticulture, precision fertigation practices, and increasing demand for high-value crop production in vegetables, fruits, and tree nuts.

Market Growth Dynamics

Between 2025 and 2030, the market is expected to grow by USD 1.5 billion, reaching USD 6.9 billion, accounting for 44.2% of the total decade-long expansion. This phase is primarily supported by the adoption of precision fertigation systems, rising protected cultivation, and the need for chloride-sensitive crop nutrition. Fertilizer manufacturers are expanding production of low-chloride specialty potassium formulations and soluble grades suitable for drip irrigation and foliar application.

From 2030 to 2035, the market is forecast to add USD 1.8 billion, representing 55.8% of total growth, driven by organic agriculture expansion, ecofriendly production practices, renewable energy integration in manufacturing, and enhanced-efficiency formulations fortified with micronutrients. The emphasis on sustainable agriculture, optimized nutrient use, and climate-smart practices will continue to boost potassium sulfate demand in high-value specialty crop systems.
