What is the relationship between sodium humate and humic acid

Sodium humate is a sodium salt of humic acid.
China has a long history of using humic acid as a medicinal product. It was applied as early as the Northern Song Dynasty (AD 1127). The “East Wall Earth Rotten Ancient Wood” and “Wu Jinshi” recorded in Li Shizhen’s “Compendium of Materia Medica” in the Ming Dynasty actually refer to It is peat and weathered coal.
However, its development and utilization is still a matter of the last half century. As early as 1902, Germany first used ammonium in peat recovery gas to make ammonium humate. Later, scientists and technicians in many countries used humic acid in industry and agriculture. He has done a lot of work in health care, etc. He started later in China. He had some early work in the late 1950s and early 1960s, but it was really encouraged and promoted by the state after the 1970s.

Humic acid and its products have many uses. China has the following products and is widely used.

  1. Agriculture
    In agriculture, humic acid fertilizers (such as ammonium humic acid fertilizers can be made by neutralizing humic acid with ammonia) in combination with nitrogen, phosphorus, potassium and other elements, with fertilizers to enhance efficiency, improve soil, stimulate crop growth, Improve the quality of agricultural products and other functions; nitrohumic acid can be used as a rice cultivating agent;
    Magnesium humate, zinc humate and humic acid urea iron have good effects in supplementing soil magnesium deficiency, corn zinc deficiency and fruit tree iron deficiency; humic acid, herbicide ether, atrazine and other pesticides can be mixed to improve the efficacy. Inhibition of residual toxicity; sodium humate is effective in treating apple tree rot.
  2. Animal husbandry
    In the animal husbandry industry, sodium humate is used for antler to stop bleeding, and nitro-humic acid urea complex is also used as a feed additive for cattle.
  3. Industry
    In industry, sodium humate is used for ceramic mud adjustment; low pressure boiler and locomotive boiler anti-scaling; humic acid ion exchanger is used for treating heavy metal-containing wastewater; sulfonated humic acid sodium is used for cement water reducing agent; humic acid product is also Used as oil drilling mud treatment agent (see oil field chemicals); purified humic acid used as lead storage battery cathode expansion agent.
