Nowadays, most fertilizers on the market will mention in their sales promotions that our products contain humic acid, and how good humic acid is, as a selling point and increase the price! This situation is common regardless of whether it is compound fertilizer or organic fertilizer! But farmer friends don’t know what humic acid is! What are the specific functions!
So, what exactly is humic acid? What is humic acid used for? Let’s take a look below.
Humic acid is a mixture of natural organic macromolecular compounds. It exists widely in nature, and the proportion of humic acid in soil is the largest. The concept of humic acid in a broad sense is: the remains of animals and plants, mainly plant remains, are caused and accumulated through the decomposition and transformation of microorganisms and a series of geochemical processes. A type of organic substance. This is the basic definition of humic acid.
Humic acid itself contains the elements carbon, hydrogen, oxygen, nitrogen, etc. required for plant growth. At the same time, it can improve the utilization rate of nitrogen, phosphorus, and potassium fertilizers. Therefore, humic acid has a very obvious effect on increasing crop yields.
Most of the soil organic matter is humic acid. Among the corrosive substances, humic acid is the main body and the salts combined with metal ions. Humic acid is the most active and effective part of the organic matter.
The most direct function of humic acid is to promote plant growth and increase crop yields.
For soil: Improve soil structure, adjust soil PH value and increase soil buffering capacity.
Biological effects: Stimulate crop growth and development. The use of humic acid can enhance the activity of various enzymes in crops, improve the ability of crops to absorb water and nutrients, enhance crop metabolism, accelerate growth and development, mature earlier, and improve quality.
In addition, from the perspective of agricultural application, humic acid also has strong drought resistance, disease resistance, low temperature resistance, and salt resistance.
In the past five years, the National Agricultural Technology Extension Service Center has carried out humic acid fertilizer test demonstrations across the country, authoritatively verifying the use of humic acid fertilizers in agriculture.
1. "Five major functions": improving soil, enhancing fertilizer efficiency, stimulating growth, enhancing stress resistance, and improving quality).
2. "Four-agent functions" (drought resistance agent, growth regulator, pesticide slow-release synergist and chemical element complexing agent).
3. "Three modernization effects" (low carbonization, ecology, and quality).
4. "Two highs and three lows" (high fertilizer utilization rate, high crop yield, low fertilizer dosage, low fertilization frequency, and low harmful gas emissions).
5. "Three doses" (fertilizer synergist, soil conditioner, rhizosphere growth stimulating agent) effect.
It can be seen that humic acid makes a very good contribution to both soil and crops. If humic acid is indeed added to the fertilizer, the effect should be good.
Development prospects of humic acid fertilizers
1.The entire process and quality control technology system of my country’s green food have reached the food quality and safety standards of developed countries such as the European Union, the United States, and Japan, and are in line with international standards. However, the fundamental problem of how to produce green and safe food is how to overcome and To prevent soil pollution, from the perspective of fertilization, we must adhere to the combination of organic and inorganic fertilizers. The use of humic acid fertilizers is the only option. The combination of humic acid and chemical fertilizers can achieve the integrated effect of 1+1>2.
2.A large number of studies have shown that humic acid is a close friend of inorganic fertilizers, a slow-release agent and stabilizer for nitrogen fertilizers, a synergist for phosphate fertilizers, a protective agent for potassium fertilizers, and a regulator and chelating agent for medium and trace elements. Humic acid It has a significant synergistic effect on chemical fertilizers and is currently the Mount Everest of chemical fertilizers in the world.
3. The future development direction of humic acid fertilizers is: intelligent, professional, compound, long-lasting, granular and regionalized fertilizers.
It can be seen that the development and application of humic acid fertilizers has broad prospects. Only by using humic acid fertilizers can we realize the greening of agricultural fertilizers and promote and promote the production and development of green agricultural products.
