What is the chemical potassium humate structure?

Potassium humate is a potassium salt of humic acid, derived from organic matter like leonardite. Chemically, potassium humate is composed of large, complex molecules with aromatic rings, carboxyl, and phenolic hydroxyl groups. These functional groups allow it to chelate nutrients, making them more available to plants. The presence of potassium ions (K⁺) improves the molecule’s solubility and enhances its role in nutrient transport within the plant. The complex molecular structure makes potassium humate an effective soil conditioner and nutrient carrier.
