The major nutrient provided by potassium sulphate includes potassium and sulphate minerals. Potassium is essential for carbohydrate for starch synthesis, and it aids plants to resist wilting. Potassium is mined from mineral deposits and potassium fertilizers are highly beneficial for plants in producing protein as they grow. Potassium sulphate also aids in eradicating microbial infections from food grains and vegetable crops.
Potassium sulphate finds application in the industrial sector in the form of a weighting agent in the oil & gas industry, potassium alum and potassium carbonate production, glass production, and in soda blasting, as an alternative to sodium bicarbonate. However, the use of potassium sulphate in industrial applications is at a nascent stage with alternatives being preferred due to lower cost. The slump in the oil & gas industry has reduced demand for potassium sulphate. For instance, the report for the nation's production was made public by the India Brand Equity Foundation (IBEF). Food grain production reached 314.51 million tons in 2020, and the government forecasted 316.23 million tons in 2021.
Among regions, Asia Pacific accounted for the largest market share, in terms of volume as well as value in 2022. The growth of the regional market is majorly attributed to the increasing adoption of fertilizers by farmers in major countries such as India, China, and Indonesia to fulfil the increasing demand for food from its ever-growing population. The increasing population in these countries is resulting in high demand for agricultural products, which is expected to drive the growth of potassium sulphate in Asia Pacific over the forecast period. According to Coherent Market Insights, Asia Pacific region held dominant position in the global potassium sulphate market with a revenue share of over 41% in 2022 and is expected to maintain its dominance over the forecast period. The region is expected to generate revenue of US$ 6,357.3 Mn by 2030.
