Types of Potassium Fulvate
Mineral Type
Potassium fulvate is a pure natural mineral active potassium element fertilizer. It contains various nutrients such as trace elements, rare earth elements, plant growth regulators, and antiviral agents. This makes the nutrient supply more abundant and balanced, thereby preventing various physiological diseases caused by the lack of elements in crops. It makes the crops more robust, the leaves greener, and enhances their resistance to lodging. Potassium fulvate can timely replenish the nutrients lost in the soil, activate the soil, and reduce the occurrence of soil-borne diseases caused by excessive nutrient absorption. The product can completely replace potassium sulfate or potassium chloride and potassium magnesium sulfate with the same content, and it is natural and environmentally friendly.
Organic Type
- Fulvic acid is a component of humic acid, which is widely found in natural substances like peat, lignite, and weathered coal.
- Using biochemical technology, fulvic acid is extracted from plants and then combined with potassium oxide to form potassium fulvate.

Main Effects of Potassium Fulvate
Potassium fulvate Fertilizer can activate compacted soil and promote the physiological metabolism of various fruits, vegetables, and field crops. It encourages the development of robust root systems and lush stems and leaves. Potassium fulvate powder can be used as a base fertilizer, a flush fertilizer, or a top-dressing fertilizer. When used as a flush or top-dressing fertilizer, the dosage per acre is about 20-30 kg. It can save various fertilizers and allow fruits, vegetables, and various field crops to mature about ten days earlier, increasing yields by more than 20%. It can also extend the shelf life and harvest period of fruits and vegetables, prevent flower and fruit drop, increase the sugar content in fruits, and improve fruit quality.
Soil Improvement: It improves soil granular structure, loosens the soil, enhances the soil’s water and nutrient retention capabilities, adjusts the pH value, and reduces the content of heavy metals in the soil. It also minimizes the harm of salt ions to seeds and seedlings.
Nutrient Activation: It fixes nitrogen, releases phosphorus, and activates potassium. It is particularly effective in enhancing the efficacy of potassium fertilizers, contributing to root strengthening, resistance to repeated cropping, disease resistance, and improving crop quality.
Root System Enhancement: It strengthens the plant root system’s adhesion and rapid absorption capabilities, especially showing significant effects on physiological diseases caused by a lack of trace elements.
Technical Indicators
Potassium fulvate is a polyphenolic aromatic compound and a condensation product of nitrogen compounds (E4/E6=3.3). It appears as a brownish powder with a sweet aroma and is a pure natural fermentation product. It has no toxic side effects and meets food hygiene standards.
Main Components
- Fulvic Acid Content (calculated on a dry basis): ≥50%
- Total Nitrogen (N) Content (calculated on a dry basis): ≥3.0%
- Total Phosphorus (P) Content (calculated on a dry basis): ≥0.4%
- Total Potassium (K2O) Content (calculated on a dry basis): ≥11.7%
- Organic Matter Content (calculated on a dry basis): ≥50%
Applicable Crops
Potassium fulvate (BSFA) employs modern biotechnology, using plant residues as raw materials and undergoing biological fermentation to successfully produce coal-like fulvic acid substances—high-activity BSFA-type biochemical potassium fulvate. (Fulvic acid has the smallest molecular weight and highest activity among humic acids, and is the essence of the effective components of humic acids.) It combines the three major advantages of composition, performance, and price, indisputably becoming the best alternative to coal-based fulvic acid.
Field Crops: Suitable for wheat, corn, and other large field crops. For these crops, the base fertilizer per acre should be 30-60 kg, in combination with appropriate inorganic fertilizers.
Economic Crops: Suitable for vegetables, fruit trees, flowers, and other economic crops. For these crops, the base fertilizer per acre should be 150-200 kg, in combination with high-concentration compound fertilizers of 30-40 kg.
Potassium Fulvate Price
The Potassium Fulvate Price varies depending on the type and quantity. However, given its effectiveness and the range of benefits it offers, it is a cost-effective solution for modern agriculture.
Water Solubility
One of the key advantages of Potassium Fulvate is its water solubility. The water-soluble Potassium Fulvate is easy to apply and ensures quick absorption by plants.
Conclusion
From its types to its myriad benefits and technical specifications, Potassium Fulvate is a game-changer in agriculture. Whether you opt for K Fulvate or its supercharged version, Super K Fulvate, you’re investing in a product that promises healthier soil and higher yields.
