Humic acid

What is humic acid?

Humic acid is a macromolecular organic compound widely found in nature.

Humic acid is an organic matter formed and accumulated through the decomposition and transformation of animal and plant (mainly plant) remains by microorganisms and a series of geochemical processes. Some fermentation processes in modern industry can also produce humic acid.

What is humic acid?

Before using magnesium sulfate heptahydrate, you must understand the concentration ratio of magnesium sulfate heptahydrate in advance. We can usually buy magnesium sulfate heptahydrate in agricultural supplies stores or online.

We usually need to wear gloves when applying fertilizer, especially magnesium sulfate, a substance that can be absorbed through the skin. Magnesium sulfate heptahydrate will not deposit in the soil, nor will it pollute groundwater. It will only make plant seedlings grow stronger, promote plant flowering, and reduce pests and diseases.

Humic acid

The raw materials of humic acid can be divided into two categories: coal-based materials and non-coal-based materials.

The former mainly includes peat, lignite and weathered coal; the humic acid content reaches 10-80%. China has very rich coal reserves. Data show that there are 5 billion tons of peat and 126.5 billion tons of lignite, but there are no statistics on weathered coal.

The latter includes soil, water, fungi and other non-coal substances, such as substances containing phenols, quinones, sugars and other substances. Humic acid substances can be produced through biological fermentation, oxidation or synthesis, such as the humic acid produced by grain fermentation to produce MSG currently on the market.


Humic acid is the main component of humus and has a complex chemical structure. It is a mixture containing active functional groups such as carboxyl group, phenol group, ketone group, and phenolic hydroxyl group. The special structure and physical and chemical properties of humic acid determine its important role in ecological restoration.
