What role does sodium humate play in aquaculture？

Sodium humate can be used in aquaculture and has many good functions.

Supplement the carbon source of water bodies. Humic acid is a polymer organic weak acid formed after the decomposition of plant residues, mainly composed of carbon.

Water purification: Sodium humate is a relatively stable natural macromolecular organic compound with aromatic structure, composed of a discontinuous network of sparse aromatic rings and many small pores in the structure. Due to its complex structure and multiple functional groups, it has high reactivity and strong adsorption.

Physical shading: Physical shading refers to the application of sodium humate to turn the water into a sauce colored substance, which can block some sunlight from reaching the bottom layer and prevent moss. It is widely used in crab breeding ponds.

Grass planting and protection: Aquatic plants should be planted in crab ponds. This is a good nutrient that can protect grass.

Chelated heavy metal ions: Sodium humate has a negative surface charge and may undergo a series of reactions with heavy metal ions in water, thus possessing ion exchange properties and the ability to form chelates with metal ions.

Improving sediment, detoxification, and deodorization: The network and porous structure of sodium humate can make the soil loose and disperse permeable bottom materials; Secondly, sodium humate can absorb some NH3 and H2S in the bottom environment, thereby removing the odor of sediment and reducing environmental pollution.
