The difference between humic acid and fulvic acid
Different origins
(1) Humic acid: It is an organic substance accumulated from the remains of animals or plants (mainly plants) through the differentiation and transformation of microorganisms and a series of chemical reactions.
(2) Fulvic acid: Extracted from low-grade coal (lignite, peat, weathered coal), the composition structure is relatively simple, and the main component is aromatic hydroxycarboxylic acid substances.
Different functions
(1) Humic acid: It can exchange, adsorb, complex, chelate, etc. with metal ions. It can be used as a polyelectrolyte in a decentralized system and has functions such as peptization, agglomeration, and dispersion.
(2) Fulvic acid: It is a plant growth regulator that can promote plant growth, improve its stress and drought resistance, and can also increase production and improve quality.
Different objects of use
(1) Humic acid: widely used in agriculture, forestry, animal husbandry, environmental protection, chemical industry, building materials, petroleum, medicine and health and other fields.
(2) Fulvic acid: Wheat, millet, tobacco, fruits, rice, rape, peanuts, corn, vegetables, sweet potatoes, cotton and other crops are the primary targets.
