Humic acid raw powder is a yellow-brown to black powder, the main components are humic acid and humus and other organic substances, is a natural organic macromolecular compounds, has a strong complexing and chelating ability. The following is a detailed analysis of humic acid powder:

I. Definition and source

Definition: Humic acid raw powder is a kind of macromolecular organic substance formed from natural organic substances such as coal mine, peat, dead leaves and other natural organic substances after biodegradation process. It contains rich organic matter and a variety of active groups, such as hydroxyl, carboxyl, phenolic hydroxyl and so on.

Source: The raw material of raw humic acid powder is not limited to coal cinders, but coal cinders are one of the important sources. In addition, peat, weathered coal, lignite, etc. are also commonly used raw materials.

Physical Properties

Appearance: The appearance of humic acid raw powder is yellowish brown to black powder.

Solubility: difficult to dissolve in water, but soluble in some organic solvents.

Acidity and alkalinity: weakly acidic.

Third, chemical properties

Active groups: It contains a large number of active groups such as carboxyl group, quinone group and phenolic hydroxyl group, which give humic acid powder high biophysiological activity.

Nutrient elements: It contains 2-4% of nitrogen, phosphorus, potassium and other nutrient elements, although the content is not high, but it has a certain role in promoting the growth of plants.

IV. Uses

Agricultural field:

As a soil conditioner, it can improve the soil structure and enhance the soil's ability to retain water and fertilizer.

As an inter-root conditioner, it promotes the development of plant roots and improves plant resistance.

As a microbial fungicide, it promotes the propagation of beneficial microorganisms in the soil and inhibits the growth of harmful microorganisms.

As an additive of organic fertilizer and compound fertilizer, improve the utilization rate and effect of fertilizer.

Water treatment field:

It can complex with harmful metal ions in water to purify water quality.

It can be used as drinking water treatment agent and industrial wastewater treatment agent.

Animal feed additive:

Improve the growth rate, immunity and disease resistance of animals.

Widely used in animal husbandry, poultry industry and aquaculture industry.

V. Production process

The production process of humic acid powder mainly includes three steps of raw material extraction, crude extraction and refining. By choosing biomass rich in humic acid as raw material, through water or organic solvent extraction, acid and alkali adjustment, filtration, concentration, crystallization and other processes, the humic acid powder with high purity and stable quality is finally obtained.

Purchase and identification

When buying and selling humic acid powder, the following points should be noted:

Check the raw material source and production process of the product to ensure reliable product quality.

Check the physical properties such as color, smell and solubility of the product to judge the purity and activity of the product.

You can find out the specific indexes and performance of the product by checking the relevant standards or consulting professionals.

In addition, when identifying the authenticity of raw humic acid powder, you can observe such characteristics as its dissolution speed, color change and whether it is activated. Usually, good quality humic acid powder has fast dissolving speed, uniform color and certain activation.

In summary, humic acid powder is a natural organic substance with wide application value, which plays an important role in agriculture, water treatment and animal feed and other fields. When purchasing and using, attention should be paid to product quality and identification methods to ensure its effect and safety.
