Potassium Bicarbonate Fertilizer Global Market Report 2025: Market Opportunities & Challenges Outlook

The global market for Potassium Bicarbonate Fertilizer was estimated to be worth US$ 49.1 million in 2024 and is forecast to a readjusted size of US$ 59.1 million by 2031 with a CAGR of 2.6% during the forecast period 2025-2031. Potassium bicarbonate fertilizer is a chemical fertilizer containing potassium and carbon and is weakly alkaline. Potassium is one of the macroelements necessary for plant growth. It can promote plant photosynthesis, improve photosynthetic efficiency, promote the synthesis and transportation of carbohydrates, make plant stems thicker, and enhance plant resistance to lodging, drought, cold and other stresses. The carbon dioxide produced by the decomposition of potassium bicarbonate can be used as a carbon source for plant photosynthesis, which helps to enhance plant photosynthesis and improve crop yield and quality. At the same time, carbonate ions can also play a certain buffering role in the soil, helping to regulate soil pH.
