The Difference Between Alginic Acid, Humic Acid And Amino Acids

1. Alginic acid
Alginic acid is a natural biostimulant extracted from seaweed, mainly found in seaweeds such as kelp and spirulina. Alginic acid has many functions such as promoting plant absorption of nutrients, increasing crop yields, and improving the quality of agricultural products. Its mechanism of action mainly includes the following aspects:
(1) Promote plant absorption of nutrients: Alginic acid can form complexes with metal ions in the soil, making the nutrients in the soil more easily absorbed by plants. At the same time, alginic acid can also promote the formation and development of plant root systems.
(2) To increase the nutritional value of plant crops: absorb the acid accumulation energy of sea-absorbed algae surface. It can promote plant photosynthesis and transpiration, improve crop stress resistance and disease resistance, thereby increasing crop yield and quality.
(3) Improve the quality of agricultural products: Alginic acid can promote the synthesis of proteins, sugars and other organic substances in plants, thereby improving the quality of agricultural products. At the same time, alginic acid can also improve the storage stability and transportation of agricultural products.
2. Humic acid
Humic acid is an organic substance formed by microbial decomposition of animal and plant residues. It mainly exists in soil, water and plants. Humic acid has many functions such as promoting plant absorption of nutrients, improving soil physical and chemical properties, and improving the quality of agricultural products. Its mechanism of action mainly includes the following aspects:
(1) Promote plant absorption of nutrients: Humic acid can form complexes with metal ions in the soil, making the nutrients in the soil more easily absorbed by plants. At the same time, humic acid can also promote the formation and development of plant roots and increase the plant's nutrient absorption area.
(2) Improve the physical and chemical properties of the soil: Humic acid can increase the organic matter content of the soil, improve the air permeability and water retention of the soil, thereby improving the physical and chemical properties of the soil.
(3) Improve the quality of agricultural products: Humic acid can promote the synthesis of proteins, sugars and other organic substances in plants, thereby improving the quality of agricultural products. At the same time, humic acid can also improve the storage stability and transportation of agricultural products.
3. Amino acids
Amino acid is an organic compound composed of carbon, hydrogen, oxygen, nitrogen, sulfur and other elements. It is the basic unit of protein. Amino acids are also used as biostimulants in agriculture. The main mechanisms of action include the following aspects:
(1) Promote plant absorption of nutrients: Amino acids can form complexes with metal ions, making nutrients in the soil more easily absorbed by plants. At the same time, amino acids can also promote the formation and development of plant root systems and increase the plant's nutrient absorption area.
(2) Improve crop yield and quality: Amino acids can promote protein synthesis in plants, thereby improving the quality of agricultural products and increasing crop yield. At the same time, amino acids can also improve the storage stability and transportation of agricultural products. In addition, amino acids can also increase soil organic matter content and improve soil structure.
