Fulvic Acid is the fraction of humic substances with the lowest molecular weight and the most active components, characterized by its lighter, yellow to yellowish-brown color. It is a type of humus soluble in water, acid, and alkali, possessing extremely high physiological activity and complexation (chelation) capacity.

Humic Acid is a class of naturally occurring, complex macromolecular organic weak acids formed and accumulated through the decomposition and transformation of plant and animal residues (primarily plants) by microorganisms, along with a series of geochemical processes.

Potassium Humate is the potassium salt of humic acid, a high-efficiency organic potassium fertilizer and soil conditioner extracted from natural lignite, leonardite, or peat. It appears as black or jet-black shiny granules or powder, is soluble in water, and its solution is alkaline.

A Soil Conditioner, also known as a Soil Amendment, refers to materials used to improve the soil's physical and chemical properties and its biological activity. It is not a primary source of plant nutrients itself but works by repairing soil structure, adjusting pH, reducing salt toxicity, increasing organic matter, and promoting beneficial microbial activity to create a healthy soil environment conducive to root growth.
