Potassium humate is a black or dark brown granular or powdery substance derived from humic acid, a major component of soil
organic matter. It is highly soluble in water, forming a colloidal solution, and exhibits a high cation exchange capacity, which enhances
soil fertility. Potassium humate is known for its high molecular weight and complex structure, containing various functional groups
such as carboxyl, phenolic hydroxyl, and quinone. These groups contribute to its ability to chelate metal ions, improve nutrient uptake
by plants, and enhance soil structure. The substance is stable over a wide pH range, making it suitable for use in different soil types.
Its hygroscopic nature means it can attract and hold water molecules, thus improving soil moisture retention. Overall, potassium
humate's physical properties make it a valuable amendment for enhancing soil health and promoting sustainable agricultural practices.
