Sodium humate is made of low-grade coal containing humic acid as raw material, obtained with caustic soda solution, then settled to remove ballast, extracted and dried, and it is a bright black powder crystal.

The main uses of sodium humate are very common. In recent years, many biological product companies have carried out scientific research on the development and design of sodium humate, and it has also been widely used in the aquatic product aquaculture industry.

According to the performance and research of the farm, the (powder) commodity with sodium humate as raw material has 3 advantages:

First, it has the effect of inhibiting the growth and development of green moss

2. It has the effect of purifying water by coagulating and coagulating in the water body.

3 is a fertilizer synergist.

However, the shortage of sodium humate in aquaculture is also very large.

First, after use (powder), all water bodies turn black for 5 to 10 days, resulting in no sunlight, no plant photosynthesis, and bacteria and algae cannot grow and develop;

2. Sodium humate has a high adhesion and coagulation effect, and the heavy metals in the water body exceed the standard, and sulfate and toxic substances agglomerate in the foundation settlement pool, which cannot be dissolved. If everything is normal, the tree will disintegrate. If sodium humate is used repeatedly, there will be rotten roots, and the roots will fall to the ground;

3. After the sodium humate is drained, the water body turns black, which will hinder the photosynthesis of aquatic plants and harm the growth and development of aquatic plants. In addition, the growth, development and reproduction of bacteria and algae will also be harmed, resulting in the reduction of dissolved oxygen in the pond, which usually causes the breeding of water plants in the pond. A series of hypoxia symptoms. The imbalance of bacteria and algae, resulting in the reduction of dissolved oxygen in the pond, it is difficult for hairy crabs to turn their shells, there is a situation where the molting does not tunnel, and the multiple of turning the shells is also small.

Therefore, the use of sodium humate (powder) in the aquatic product breeding industry at this stage is an incomplete commodity, and the farm should use it with caution, and it should not be reused many times.
