Relationship between potassium humate and humic acid.

Potassium humate is essentially the potassium salt of humic acid. It is produced by extracting humic acid from natural sources like leonardite or lignite coal and then reacting it with potassium hydroxide (KOH). This process results in a water-soluble form that is more readily available for plant uptake. Humic acid itself is a complex mixture of organic compounds that improve soil health by enhancing nutrient availability, stimulating microbial activity, and improving soil structure. By converting humic acid into potassium humate, the product not only retains these benefits but also provides an essential nutrient—potassium—that supports various physiological functions in plants, such as enzyme activation and water regulation.
