Application and Prospect of Potassium Fulvicate in Aquaculture
01
1. Overview of Potassium Fulvicate
1.1 Introduction to Potassium Fulvicate
Potassium humate, a highly efficient compound fertilizer combining fulvic acid and potassium ions, is derived from natural lignite or weathered coal. This organic acid is not only rich in organic matter but also contains a variety of bioactive components, providing comprehensive nutritional support for plants and aquatic organisms. The properties of potassium humate make it remarkably effective in improving water quality .
1.2 ◉ Main components and mechanism of action
The key components of potassium humate include fulvic acid and potassium ions. Fulvic acid, with its chelating, adsorption, and complexing functions, can effectively remove heavy metal ions and harmful substances from water, while also promoting the growth of beneficial microorganisms. Potassium ions, as an essential nutrient for plant growth, have a significant effect on improving plant disease resistance and growth rate .
1.3 ◉ Application Background
In aquaculture, potassium humate is increasingly widely used, covering multiple aspects such as water quality regulation, algae control, and enhancing fish immunity. Its natural and environmentally friendly properties make potassium humate a gradually emerging ideal alternative to traditional chemical agents .

2. Usage and Effects
2.1 ◉ How to use
Potassium humate has a variety of flexible applications in aquaculture. Simply dissolve an appropriate amount of potassium humate in water and then evenly sprinkle it into the fishpond. It is recommended to use 5-10 kg of potassium humate per acre of water surface, repeating this process monthly. It effectively regulates water quality, controls algae , enhances immunity, and promotes the growth of aquatic plants, ensuring the health and growth of fish.
2.2 ◉ Usage Effect
Potassium humate has significant effects in aquaculture, specifically in the following aspects: Potassium humate can effectively reduce the concentration of harmful substances such as ammonia nitrogen and nitrite in water , ensuring clear and transparent water quality, while also improving the transparency of the water body, creating favorable conditions for the growth and reproduction of fish.

3. Precautions and Outlook
3.1 ◉ Precautions for use
Although potassium humate has shown significant benefits in aquaculture, the following points should be noted when using it: Appropriate dosage is crucial ; excessive use may lower the pH of the water, thus interfering with normal fish growth. Avoid mixing with alkaline substances and do not use it simultaneously with chlorine-containing disinfectants. Furthermore, potassium humate is not suitable for all types of water bodies.
3.2 Future Outlook
With increasing environmental awareness, potassium humate, due to itsenvironmentally friendly properties, will be more widely used in aquaculture in the future . The market demand for high-efficiency and environmentally friendly fertilizers is constantly rising, demonstrating the enormous market potential of potassium humate . Its market demand is expected to remain strong in the future. In-depth research into the mechanism of action and optimal application conditions of potassium humate will provide a more solid scientific basis for its application in aquaculture, thereby promoting the sustainable and healthy development of the aquaculture industry.
