Human studies of humic acid have been 214 years old since the first time in 1786. If the “Wu Jin San” compiled by Li Shizhen’s “Compendium of Materia Medica” in the Ming Dynasty’s famous medicine scientist in the Ming Dynasty is a case, the application of humic acid has been used for more than 400 years, which fully illustrates the humic acid. Ancient history.
The organized study of humic acid in China began in the late 1950s, mainly from the use of peat. In the 1960s, the country’s enthusiasm for using humic acid fertilizers and improving soils was very strong. Really valued and promoted by the state is after the mid-1970s. At that time, Vice Premier Wang Zhen of the State Council also personally arrested. The State Council successively promoted the comprehensive development and utilization of humic acid in China in 1974 and 1979 with Guofa No. 110 and No. 200 documents. In the 1980s, with the continuous development of the national humic acid business, the State Economic and Trade Commission approved the establishment of the “China Humic Acid Industry Association” in 1987, responsible for the unified organization and coordination of the national humic acid work. Some provinces and cities with large reserves of humic acid resources have also included government work sequences, and the Humic Acid Office has been set up specifically for this purpose.
- Humic acid
The true nature of the black land is humic acid. She is the core force of soil life, the “heart” of black soil, and the “gold standard” for testing soil fertility. To protect the black land, we have the wisdom that the humic acid extracted by the industry is backed up in large quantities to restore its original appearance.
Humic acid function
1. Supplement soil organic matter.
2. Replenish carbon and nitrogen, dissolve phosphorus and dissolve potassium, and improve fertilizer efficiency.
3. Enhance the ability of crops to resist cold, drought, and heavy mites, and prevent pests and diseases.
4, promote root development, robust plants.
5. Adjust soil acid-base balance and improve soil micro-ecological environment.
6. Improve production and improve quality.
