Humic acid is a mixture of natural organic macromolecular compounds. Humic acid is widely present in nature, with the largest proportion in soil. In a broad sense, the concept of humic acid refers to a type of organic matter formed and accumulated through the decomposition and transformation of animal and plant remains, mainly plant remains, by microorganisms, as well as a series of geochemical processes. This is the basic definition of humic acid.
In soil organic matter, humic acid is generally the main component. In corrosive substances, humic acid is the main body and its salts combined with metal ions. Humic acid is the most active and effective part of organic matter.
1.The "five major functions" : improving soil quality, enhancing the efficiency of chemical fertilizers, stimulating growth, strengthening stress resistance, and improving quality.
2. "Four Functions" : drought resistance agent, growth regulator, pesticide slow-release enhancer and chemical element complexing agent.
3. "Three Effects" : Low-carbonization, ecologicalization, and high quality.
4. "Two highs and three lows" : High fertilizer utilization rate, high crop yield, low amount of fertilizer applied, low frequency of fertilization, and low emission of harmful gases.
5. "Three-agent integration" : It has the effects of a fertilizer efficiency enhancer, a soil conditioner, and a rhizosphere growth stimulant.
