Potassium sulphate market to hit $9.56 billion by 2030

The global potassium sulphate market is projected to grow from $5.88 billion in 2025 to $9.56 billion by 2030, driven by fertilizer demand, organic farming and high-yield crops. Asia-Pacific leads today, while North America is expected to post the fastest growth.

Why it matters: - Potassium sulphate is a chloride-free source of potassium and sulfur, two nutrients that support crop growth without some of the soil risks tied to chloride-based fertilizers. - The market’s growth points to rising demand for fertilizers that fit both yield goals and sustainability priorities. - The expanding organic food sector is adding another layer of demand for chloride-free inputs.

What happened: - The Business Research Company released its Potassium Sulphate Global Market Report 2026, covering market size, trends and forecasts through 2035. - The report puts the market at $5.88 billion in 2025 and $6.48 billion in 2026. - The report forecasts the market will reach $9.56 billion by 2030. - The report estimates a 10.4% CAGR in 2026 and a 10.2% CAGR from 2026 to 2030. - Asia-Pacific held the largest market share in 2025. - North America is expected to be the fastest-growing region over the forecast period. - The report includes coverage of Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, the Middle East and Africa. - A free sample of the report is available. - The full market report is also available.

The details: - Potassium sulphate is a white, water-soluble inorganic compound. - The compound is commonly produced by combining potassium bisulfate with sulfuric acid. - Fertilizer production is its main use. - Potassium sulphate also serves as a reducing agent in some chemical industry processes. - Historical growth has been supported by rising use of agricultural fertilizers, expansion of cash crop farming, growing soil nutrient deficiencies, wider adoption of potassium-based fertilizers and improved fertilizer manufacturing capacity. - Future growth is expected to come from demand for high-yield crops, broader acceptance of sustainable fertilizers, growth in horticulture, expansion of food processing and better fertilizer application methods. - Emerging trends include more use of sulfur-free potash fertilizers, greater use in high-value crops, more specialty fertilizer blends, expanded industrial chemical applications and stronger demand for chloride-free potassium sources. - Organic food sales in the U.S., including organic non-food products, reached $60 billion in 2022 and rose to a record $67.6 billion in 2023, according to the Organic Trade Association in May 2023. - USDA data released in January 2025 showed estimated U.S. sorghum grain production for 2024 rose 8% to 344 million bushels from the prior year.

Between the lines: - The report ties potassium sulphate’s outlook to a broader shift toward fertilizers that support productivity while limiting chloride exposure. - The organic farming expansion suggests demand is no longer coming only from conventional agriculture. - Regional leadership in Asia-Pacific and faster growth in North America suggest the market is developing on both production intensity and premium-crop demand. - The report’s emphasis on specialty blends and industrial uses suggests potassium sulphate’s market base is widening beyond standard field fertilization.

What’s next: - Demand is expected to keep rising as growers seek higher yields and more sustainable input choices. - Market growth may continue to accelerate in horticulture, specialty crops and organic production. - The report points to continued opportunity in fertilizer innovation, application methods and regional expansion.

The bottom line: - Potassium sulphate is moving from a niche fertilizer input to a broader growth market, with demand supported by food production, organics and chloride-free crop nutrition.
