Potassium Sulphate Market Report 2026

The potassium sulphate market size has grown rapidly in recent years. It will grow from $5.88 billion in 2025 to $6.48 billion in 2026 at a compound annual growth rate (CAGR) of 10.4%. The growth in the historic period can be attributed to growth in agricultural fertilizer consumption, expansion of cash crop farming, rising soil nutrient deficiencies, increased use of potassium based fertilizers, development of fertilizer manufacturing capacity.

The potassium sulphate market size is expected to see rapid growth in the next few years. It will grow to $9.56 billion in 2030 at a compound annual growth rate (CAGR) of 10.2%. The growth in the forecast period can be attributed to rising demand for high yield crops, increasing adoption of sustainable fertilizers, growth in horticulture farming, expansion of food processing industries, innovation in fertilizer application techniques. Major trends in the forecast period include rising demand for sulfur free potash fertilizers, increasing use in high value crop cultivation, growing adoption in specialty fertilizer blends, expansion of industrial chemical applications, higher preference for chloride free potassium sources.

Rising demand for food crops is driving the growth of the potassium sulphate market. Potassium sulphates are applied in various agricultural processes, including the provision of potassium for optimal plant growth, particularly in soils where chloride accumulates from irrigation water. The use of potassium sulphate is gaining traction in agriculture due to its low chloride content, which helps prevent crop damage. For instance, in January 2025, according to the United States Department of Agriculture, a US-based government organization, Sorghum grain production in 2024 is estimated at 344 million bushels, reflecting an 8% increase compared to 2023. Thus, rising agricultural production is expected to increase the demand for potassium sulphates, driving market growth during the forecast period.

The growing demand for organic food is also expected to propel the potassium sulphate market going forward. Organic food refers to agricultural and food products produced through environmentally sustainable and natural farming practices that minimize the use of synthetic chemicals. Potassium sulphate is utilized in organic farming as an essential macronutrient, supporting plant physiological processes and ensuring optimal growth by providing a balanced source of potassium, which is vital for root development, flowering, and fruiting. For instance, in May 2023, according to the Organic Trade Association, a US-based industry organization, total organic sales, including non-food products, reached $60 billion in 2022, rising to a record $67.6 billion in 2023, reflecting significant growth in the organic sector. Therefore, increasing demand for organic food is driving the growth of the potassium sulphate market.

Major companies operating in the potassium sulphate market are focused on introducing advanced solutions, such as oral solutions, to provide a competitive edge in the market. Oral solutions are a type of medication that comes in liquid form for drinking and are used for various purposes, such as cleansing the colon as a preparation for colonoscopy. For instance, in September 2023, Lupin Limited, an India-based pharmaceutical company, launched the Suprep Bowel Prep Kit, approved by the Food and Drug Administration, a US-based federal agency. Suprep Bowel Prep Kit is an oral solution that contains sodium sulfate, potassium sulfate, and magnesium sulfate. It is used for cleansing the colon as a preparation for colonoscopy. It provides a more affordable option for patients.
