Premium Potassium Bicarbonate (KHCO₃) – High Purity Multi-Purpose Water Soluble Grade

Our Premium Potassium Bicarbonate (KHCO₃) is a high-purity, crystalline white powder, fully water-soluble formula suited to a wide range of agricultural, horticultural, and general-purpose applications. Supplying around 39% potassium (equivalent to 47% K₂O) with no sodium and no chloride, it delivers potassium to plants without the salt build-up associated with other potassium sources.

This premium-grade potassium bicarbonate dissolves rapidly in water for easy application and consistent performance. It is naturally alkaline, making it a practical choice where soil, reservoir, or irrigation water pH needs lifting. Suitable for foliar spray, soil application, hydroponic systems, and other practical uses where high purity and reliable quality matter.

Fully soluble in water, it can be applied through foliar spray, soil drench, or fertigation systems depending on application requirements. Always use appropriate dilution rates for your intended use.
