The difference between fulvic acid and humic acid lies in their different sources, functions and applications.
Source: fulvic acid is extracted from peat, lignite and weathered coal. Humic acid is an organic substance accumulated from the remains of animals and plants after microbial decomposition and transformation.
Function: fulvic acid can improve the stress resistance of crops. Humic acid can be used to make humic acid fertilizers. Such products can improve soil and stimulate crop growth.
Application: fulvic acid is mainly used for crops. Humic acid is widely used in forestry, agriculture, animal husbandry, chemical industry and other fields.
I. What is the difference between fulvic acid and humic acid?
1. Different sources
(1) fulvic acid: extracted from low-grade coal (peat, lignite and weathered coal). Its composition structure is relatively simple and mainly consists of aromatic hydroxycarboxylic acid substances.
(2) Humic acid: refers to humic acid, which is a type of organic substance accumulated from the remains of animals or plants (mainly plants) after microbial decomposition and transformation, as well as a series of chemical reactions.
2. Different functions
(1) Fulvic acid: It can be used as a plant growth regulator to promote plant growth, improve plant resistance to drought and stress, increase yield and improve quality.
(2) Humic acid: Humic acid fertilizers made by combining with nitrogen, phosphorus, potassium and other elements (humic acid can be made into ammonium phytate fertilizer by neutralizing humic acid with ammonia), which have the effects of increasing fertilizer efficiency, improving soil, stimulating crop growth and improving agricultural product quality.
3. Different application objects
(1) Fulvic acid: It is mainly used for vegetables, fruits, rice, corn, wheat, millet, sweet potato, cotton, rapeseed, peanuts, sericulture, tobacco and other crops.
(2) Humic acid: It is widely used in forestry, agriculture, animal husbandry, chemical industry, petroleum, medicine and health, building materials, environmental protection and other fields.
II. Uses of fulvic acid
1. Used for spraying crops to resist drought and dry hot wind. When spraying wheat, the average stomatal opening can be reduced by about 2/3, while also enhancing root vitality, increasing the activity of various enzymes, increasing the chlorophyll content by more than 20%, and preventing premature aging.
2. It can be used as an effective ingredient in liquid compound fertilizers such as “leaf treasure”, “plant protection”, “high yield spirit”, “plant growth hormone”, and various trace element fertilizers.
3. Foliar spraying of economic crops such as grapes, peanuts, apples, vegetables, watermelons, and tea can improve the quality of fruits (acidity decreases, sugar content increases by 2-4 degrees).
4. When used on cotton, it can prevent and control yellow wilt and increase cotton production by 15-30%.
5. As a feed additive, it can increase the appetite of pigs, tenderize and fatten them, increase the hatching rate of chickens by 21.8%, the egg production rate of chickens by 15.5%, the healthy chick rate by 15-20%, and prevent livestock diseases and chicken plague.
