Leonardit - natural slate hydrocarbon formed in the earth over millions of years by chemical and biological decomposition of prehistoric plants and animals. It contains a high concentration of humic acids due to high microbial activity.
Features of humic acid:
- environmentally friendly bio-stimulator , which can be used throughout the cycle of plant growth;
- helps improve moisture content and soil structure and help maintain its stability;
- form the salt of the inorganic minerals in a form that can be easily assimilated by the plants;
- plant provides power confrontation of illness, as well as increasing strength and quality of the root growth of plants;
- increases soil permeability , increases the ability to retain moisture and reduce evaporation, developing useful colonies of microbes around the root.
Leonardit used for the production of fertilizers such as sodium humate and potassium humate .
One type of organic deposits is Leonardite mineral. These are formations that cannot yet be called coal because they contain more water and organic matter within them. They cannot be called fuel because they burn weakly. Essentially, leonardite is a soft brown coal, the initial stage of its formation, although its age is measured in millions of years. The main value of such coal-like substance lies in its high content of humic acids. It is mined and used in the production of humic fertilizers.

Description
Humic acid fertilizer in agriculture is a high polymer heterogeneous aromatic hydroxyl carboxylic acid. Humic acid is black brown powder or granular, insoluble in water and is of weak acidity, easily soluble in alkali. It comprises hydroxyl, carboxylic, phenolic hydroxyl, active groups.
Usage
1) Agriculture : organic fertilizer, raw material for humates based fertilizers and also can be used as soil ameliorator, plant growth stimulator and fertilizer improver.
2) Industry: Used as oil drilling fluid stabilizer, cement and ceramic additive, wastewater treatment agent, cathodal plate additive for accumulator.
Storage
Humic acid fertilizer should be kept in sealed, dry and ventilated place. It won't deteriorate in long-term storage. Agglomeration and pulverization doesn't affect use after it' s dissolved.
25KG or 50KG net woven bag; according to customers' requirement.
