Sodium humate is widely used as a soil conditioner in agriculture. It improves soil quality, enhances water retention, and increases plant nutrient uptake. It’s also used in fertilizers to promote healthier and more robust plant growth. In addition, sodium humate has also made great achievements in the aquaculture industry.
Sodium Humate Used In Aquaculture
The Use of Sodium Humate in Aquaculture
Sodium humate can chelate and degrade water body comprehensive toxins, resist stress and inhibit bacteria and viruses, activate pool water, adjust pH value, supplement water body nutrients, and effectively adsorb and decompose harmful substances such as ammonia, nitrogen, hydrogen sulfide, and nitrite.
Scope of application: All marine and freshwater high-density aquaculture water bodies.
Improvement of aquaculture water bodies with deteriorating ecological environment of various aquaculture (such as: thick and old water, deterioration of bottom quality, high pH value, heavy metal ions and organic pesticide residues, typhoon stimulation, early spring thaw, continuous high temperature, etc.)
Main effects
- Relieve the symptoms of poisoning caused by heavy metal ions (mercury, zinc, copper, lead) and organic pesticides.
Effectively remove algae toxins, prevent algae poisoning caused by large-scale death of algae after the application of insecticides and fungicides, neutralize toxins, heavy metals, etc.
- Prevent pond aging, eliminate organic foam on the water surface, effectively purify the water color algae phase, balance pH value, stabilize the water ecological environment, and effectively control the stress response of farmed animals.
Using the comprehensive adsorption characteristics of sodium humate, it can assist in the treatment of turbidity, bottom flooding, dead algae, oil film, foam and other water quality conditions.
Sodium humate is mainly composed of carbon, hydrogen, oxygen, nitrogen and other elements, which can supplement the carbon source of water body. At the same time, sodium humate is a relatively stable natural macromolecular organic matter with aromatic structure.
It is a discontinuous network composed of sparse aromatic rings, and there are many pores of different sizes in the structure.
Due to its complex structure and multiple functional groups, it has high reactivity and strong adsorption performance.
Therefore, it can achieve the effect of purifying water quality in practical applications. Sodium humate itself can release primary ecological oxygen, thereby inhibiting the growth of certain bacteria.
- Alleviate the production of red tides and “water blooms”, degrade harmful substances such as ammonia nitrogen, nitrite, hydrogen sulfide, increase dissolved oxygen in water, and improve water quality and bottom quality. Humic acid is a relatively good carbon source fertilizer after decomposition.
Some special uses can also stimulate the rapid reproduction of algae. This use should be more cautious at the moment when the breeding environment is deteriorating.
However, sodium humate is a development trend of carbon source fertilizer products in the future. It can provide a large amount of carbon source for the growth of algae in ponds.
Many manufacturers often add a certain amount of sodium humate to their powder and liquid detoxification products. One is to adjust the color, and the other is that it does have the additional effects of purifying water, refreshing water, detoxifying, and assisting in algae cultivation.
Sodium Humate Used In Aquaculture
Common Uses
- Water conditioning and water purification: The adsorption and complexation characteristics of sodium humate can assist in treating turbidity, bottom flooding, dead algae, oil film, foam and other water quality conditions. Suppose it is matched with water purifiers (such as polyaluminum, activated carbon, etc.), oxidants (such as chlorine dioxide, potassium persulfate, potassium ferrate, etc.), bacterial preparations (such as photosynthetic bacteria, spores, lactic acid bacteria, etc.), and detoxifiers (such as organic acids, EDTA, baking soda, etc.). In that case, the water conditioning and water purification effect will be better.
It should be noted that sodium humate has an adsorption effect, and naturally there will be a common problem of adsorbed drugs: the toxicity aggregation effect. Especially for benthic organisms such as shrimps and crabs, this side effect must be paid special attention to. It is precisely because of this side effect that it has a subsequent impact on the water body, and the farmers did not notice it when using it, which will lead to many effects that should be achieved. For example, the accumulation of toxins will naturally consume oxygen seriously. The oxygen consumption will naturally reduce the effect of algae and fungi, and even cause the death of algae and fungi. Once the algae and fungi are inhibited or die, let alone the effect of water purification and water adjustment, even the originally beautiful water will become turbid and ugly.
- Shading: relying on the physical properties of humic acid, but in fact, the shading time of pure humic acid is only one or two days at most. The shading effect on the market is either very high (unlikely) or a certain amount of melanin is added. This method of use is risky and not suitable for use in the middle and late stages of aquaculture. Even in the early stage of use, special attention should be paid to the liver and stomach conditions of fish and shrimp. If the liver and stomach are not good, it is best not to use it indiscriminately (easy to be poisoned).
This method of use is specifically for the two situations of poor algae phase and difficult to adjust, and moss growth and difficulty in fertilizer. Before use, the algae phase must be strictly examined under a microscope, and during use, drugs that control the algae phase must be used to target algae cultivation and water adjustment products. To avoid harmful algae after the shading time is over.
- Soil improvement: Humic acid can improve the soil (especially for sandy soil), and is generally used with oxygenators, detoxifiers, disinfectants, bacterial preparations, etc. In recent years, the concept of water adjustment is more inclined to be used with bacterial preparations and oxidants.
However, this method is not recommended for aging ponds, clay ponds, and ponds with thick silt.
- Detoxification:
Complex toxins, heavy metals, etc. In many manufacturers’ powder and liquid detoxification products, a certain amount of sodium humate is often added. One is to adjust the color, and the other is that it does have the additional effects of purifying water, refreshing water, detoxification, and assisting algae cultivation.
Once a certain amount of sodium humate is added to the detoxification product, a very popular product can be turned into a functional product that may have a surprising effect. But it should be noted that if the amount is not enough, everything will be in vain.
- Fertilizer and water: Humic acid is a relatively good carbon source fertilizer after decomposition. Some special uses can also stimulate the rapid reproduction of algae. This use should be more cautious at the moment when the aquaculture environment is deteriorating.
However, sodium humate is a development trend of carbon source fertilizer and water products in the future.
With the development of aquaculture, nitrogen source pollution is getting more and more serious. The concept of using carbon to expel nitrogen is no longer just a concept, but has been actually used in aquaculture production by many farmers.
Usage and dosage
Generally, for a pond with a water depth of 1 meter, the dosage per mu is 1-2Kg. The dosage of the reservoir needs to be increased. It is applied once every 20 days or so. When the water quality deteriorates, the dosage is doubled. Just spread the powder or granules throughout the pond.
It is better to use it in combination with oxygenators, photosynthetic bacteria, EM bacteria, enhanced Yikang bacteria, etc. Generally, for old ponds with deteriorating bottom, use granules; if the water body is deteriorating, use powder.
