2. Product Overview
Leonardite, also known as oxidized lignite or brown coal, is a naturally occurring mineral formed from the oxidation of lignite coal. It is characterized by its high content of humic acid and fulvic acid, which are complex organic molecules that play a crucial role in soil fertility and plant nutrition. Leonardite is a rich source of organic matter, typically containing 40%–90% humic substances, along with trace elements and minerals.
The primary application of Iranian leonardite is as a soil conditioner and organic fertilizer. When applied to soil, humic and fulvic acids improve soil structure, increase water-holding capacity, enhance cation exchange capacity (CEC), and stimulate microbial activity. They also chelate essential nutrients, making them more available to plants, and promote root development and overall plant growth. Leonardite is used in conventional and organic farming, horticulture, landscaping, and turf management. It is also a key raw material for the production of liquid humic acid concentrates, potassium humate, and other humic-based fertilizers.
