Humic acid is the best organic matter. Some customers may have heard this statement. But why humic acid is the best organic matter? Is this statement accurate? Today we will answer this question. Hope to give our customers some help.
In fact, this statement is mainly due to the effect of humic acid.
The effects of humic acid can be summarized into five categories:
Humic acid is a soil conditioner
With the improvement of people’s living standards and changes in lifestyles, as well as the development of the inorganic fertilizer industry, farmyard manure is increasingly being ignored by modern farmers.
Therefore, from the current fertilization structure, the fertilization habit of applying more inorganic fertilizers and less organic fertilizers is very common, especially in the production of food crops. If things go on like this, it will inevitably destroy the soil structure, cause soil compaction and decrease soil fertility. Based on this status quo, it is particularly important to develop convenient and hygienic organic fertilizer sources.
Humic acid can promote the formation of soil aggregate structure, reduce soil bulk density, increase cation exchange capacity, and adjust soil pH, thereby helping to improve soil’s water retention, fertilizer retention, heat preservation and aeration capacity.
In addition, because humic acid is a macromolecule organic matter, it can provide sufficient carbon source and energy for soil microorganisms, promote the metabolism and reproduction of microorganisms, and increase the retention of soil microorganisms. It can also enhance soil microbial activity and improve the soil microenvironment, which is particularly important for improving and fertilizing the soil.
Humic acid is a synergist of fertilizer
The application of NPK fertilizer has played a decisive role in increasing the yield of agricultural products, but the phenomenon of high yield and inefficiency has become a common problem in the high-yield cultivation of crops. How to strengthen the comprehensive management of nutrient resources and improve the utilization rate of fertilizers is becoming the focus of research in modern agricultural management systems.
To this end, the Chinese government has invested a large amount of financial funds since 2005 to launch soil testing and formula fertilization projects across the country, aiming to achieve high yield, quality and efficiency in agriculture by guiding farmers to apply fertilizers scientifically.
In the face of such a situation, the multiple functions of humic acid in controlling nitrogen and slow release, dissolving phosphorus and increasing efficiency, preventing potassium leaching, and activating micronutrient elements are particularly important. It can greatly improve fertilizer efficiency and balance nutrient supply.
Humic acid is a good pesticide adjuvant.
Humic acid foliar fertilizer as a good pesticide adjuvant is mainly reflected in the following aspects:
1. Humic acid is composed of complex organic matter. The molecule contains more hydrophilic and lipophilic groups, which act as a surfactant. When mixed with pesticides, it can effectively exert its good dispersion and emulsification effects, thereby improving the activity of pesticides and increasing the efficacy of pesticides.
2. Humic acid has a large surface area and has a strong adsorption effect on organic and inorganic substances. It will form some complexes when compatible with pesticides, which can release the effect of pesticides slowly.
3.Since the functional groups of humic acid molecules contain amino groups and S- groups, they can reduce the toxic effects of pesticides on humans and animals, thereby improving the safety of pesticides to a certain extent.
4.Highly active fulvic acid has a solubilizing and synergistic effect on pesticides, so it can reduce the amount of pesticides used to a certain extent, thereby reducing the delivery of pesticides in the food chain and the residues in the environment.
5.Humic acid is also beneficial to the degradation of pesticide residues in the soil. Because humic acid promotes the reproduction of microorganisms in the soil, and the microorganisms can effectively degrade pesticide residues in the soil, after application, it can effectively reduce the environmental pollution of pesticide residues, reduce the entry of pesticides into the food chain, and reduce the accumulation of pesticides in animals and plants.
In addition, humic acids themselves have functions similar to pesticides. Studies have shown that after spraying humic acid foliar fertilizer, the incidence of pepper bacterial wilt, incidence of peanut rust, and fruit rotten rate are significantly reduced.
Humic acid is an antidote to pollutants
The environmental quality of agricultural production areas is the most important for the safe production of agricultural products.
Humic acid is rich in active functional groups such as carboxyl and phenol carboxyl. Its strong adsorption of metal ions and organic pollutants is of great significance to alleviating heavy metals and organic pollution. Studies have shown that in a solution containing 50 mg of mercury per liter, at pH=2, the adsorption capacity of peat on mercury can reach 90%, and the adsorption capacity of copper in ammonia solution can reach 100%.
Soluble chromium and cadmium are very toxic heavy metal elements. Studies have shown that when the pH value is low, the active functional groups in humic acid play a reducing role. After humic acid is applied, the toxic heavy metal ions in the soil undergo an adsorption reaction, thereby significantly reducing its toxicity.
Humic acid can adsorb organic pollutants such as polycyclic aromatic hydrocarbons, polychlorinated biphenyls, pesticides, and herbicides through hydrophobic interaction, ligand exchange, and hydrogen bonding. Through the fixed precipitation, reduce its active concentration in the environment and reduce its pollution to the environment. It can also degrade macromolecular organic compounds into small molecular organic compounds through redox.
In addition, after being applied to the soil, it can also stimulate the activity of microorganisms and enzymes in the soil to improve the self-purification ability of the soil, thereby indirectly promoting the degradation of organic matter. Or by promoting the growth of plants and the changes in the physiological and metabolic functions of the plants themselves, thereby enhancing the ability of plants to degrade and purify organic pollutants.
Humic acid is a plant growth promoter
Soil application of humic acid fertilizer or foliar spraying of humic acid can increase the germination rate and germination potential of seeds, stimulate the growth of crop roots, increase metabolic enzyme activity in plants, enhance crop resistance and improve photosynthesis efficiency.
The quality of agricultural products has been significantly improved because the effect of humic acid on plant growth is similar to that of plant hormones. Therefore, for recipient plants, humic acid is a regulator or promoter of plant growth.
Humic acid is the best organic matter because of its comprehensive and effective effect on agriculture. If your crop has the problems mentioned in the above content, you might as well try to use humic acid products, I believe it will bring you good benefits.
