What does humic acid do

First, improve the soil

Improve soil structure: Humic acid is an organic colloid with strong adsorption capacity. It can adsorb cations in the soil and form aggregates, thereby improving the soil structure and increasing the water and fertilizer retention capacity of the soil.

Regulating soil pH: Humic acid contains a variety of functional groups, which can neutralize the pH of the soil and keep the pH of the soil within the range suitable for crop growth.

2. Provide nutrients

Humic acid itself contains many nutrients needed by plants, such as carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron and so on. These elements exist in organic form and are easy to be absorbed and utilized by plants. In addition, humic acid can also combine with inorganic salts in the soil to form soluble humic acids and improve the availability of nutrients in the soil.

Third, stimulate crop growth

Humic acid can stimulate the root development of crops and improve the absorption capacity of roots. At the same time, it can also promote the photosynthesis of crop leaves, increase the content of chlorophyll, and improve the resistance of crops (such as drought resistance, cold resistance, disease resistance, etc.). In addition, humic acid can also promote the early ripening and yield increase of crops.

4. Chelating heavy metals

Humic acid molecules contain a variety of functional groups, such as carboxylic groups, phenolic hydroxyl groups, etc., which can form stable chelates with heavy metal ions, thereby reducing the toxicity and mobility of heavy metals in soil. This is of great significance to prevent heavy metal pollution of soil and groundwater.

5. Environmental protection

Humic acid is also widely used in environmental protection. For example, it can be used as a flocculant for wastewater treatment, which can effectively remove pollutants such as suspended matter, organic matter and heavy metal ions in wastewater. In addition, humic acid can also be used for soil remediation, through adsorption, chelation and transformation, reduce the concentration of pollutants in the soil and improve the quality of the soil environment.

6. Industrial applications

Humic acid also has a variety of applications in industry. For example, it can be used as drilling mud treatment agent, ceramic additive, rubber reinforcing agent, ink thickening agent and so on. In addition, humic acid can also be used to prepare agricultural inputs such as biofertilizers and biological pesticides.

Humic acid has a variety of functions and functions, and has a wide range of application prospects in agriculture, industry, environmental protection and other fields. With the deepening of people's understanding of humic acid and the continuous progress of technology, the application field of humic acid will be more extensive and make greater contributions to the sustainable development of mankind.
