Since humic acid has a variety of excellent effects on crops, humic acid is added to most bio-organic fertilizers and compound fertilizer raw materials on the international market. Fertilizer manufacturers are optimistic about humic acid for several reasons:
1. From the perspective of the formation process of humic acid. Humic acid is a type of organic substance formed through the decomposition and transformation of animal and plant remains through microorganisms during a series of geochemical changes. Humic acid itself has the function of stimulating the growth of microorganisms and higher plants.
2. Humic acid can serve as a source of food and energy for microorganisms and algae, which must be quite beneficial to the functional microbial combination flora contained in fertilizers. It can promote the rapid reproduction of microorganisms after being applied to the soil, thereby increasing the growth rate in the soil. form dominant bacterial flora.
3. Humic acid is a high-quality chelating agent that can effectively chelate metal ions and trace elements in the environment and reduce their immobilization by soil. These metal ions are activators of many important enzyme systems of functional microorganisms. Therefore, humic acid plays an important role in both the growth and reproduction of microorganisms and the activation of their biological enzyme systems.
4. Fertilizer manufacturers use humic acid not just as a carrier and filler, but also involve it in the entire process of bio-organic fertilizer production. First of all, humic acid participates in the decomposition and fermentation of organic matter such as poultry manure. It can not only adjust the carbon-nitrogen ratio in the fermentation pile and make the fermentation process ideal, but it is also an excellent adsorbent that can absorb animal and plant proteins in the fermentation process. The ammonia produced during the decomposition process is absorbed to form ammonium humate. During the fermentation process, its own peptides and proteins are also reduced to amino acids with smaller molecular weights, which will be beneficial to the absorption and utilization of microorganisms and crops in the soil; secondly, humic acid is loaded with trace elements and medium elements in the core material Together, they can effectively form metal organic chelates. Humic acid can also improve the permeability of cell membranes, which will also facilitate the absorption and utilization of nutrients in the soil by microorganisms and crops.
5. Many research data show that humic acid has a strong anti-transpiration effect, which is very beneficial to enhancing the drought and cold resistance of crops.
In summary, humic acid is a bioactive substance with considerable fertilizer efficiency, green and pollution-free, and is a high-quality raw material for the production of bio-organic fertilizers and compound fertilizers.
