Potassium Fulvate Water Soluble Powder is a black/dark brown powdery solid produced from weathered coal, lignite, or Leonardite through extraction and conversion with potassium hydroxide. It belongs to the high-molecular-weight aromatic hydroxycarboxylic acid potassium salt category (CAS No.: 68514-28-3), is water-soluble and alkaline, and contains active carboxyl and phenolic hydroxyl functional groups.
Characteristics of Potassium Fulvate Water Soluble Powder:
1. Composition and Content: Typical dry basis indicators are humic acid ≥45% and potassium oxide 8%–10%; some high-purity products indicate fulvic acid content.
2. Water Solubility Definition: High-quality Potassium Fulvate Water Soluble Powder, after filtration through a 0.45μm filter membrane at 20℃, retains ≥95% of the effective components in the filtrate (not simply “instantly soluble in water”), ensuring no residue clogs the drip irrigation system.
3. Morphological Advantages: Potassium Fulvate Water Soluble Powder, with a particle size D90 ≤ 45μm, is an air-jet-milled powder with a large specific surface area (8–12 m²/g), resulting in rapid dissolution and uniform dispersion, making it suitable for fertigation and precise metering.
Applications of Potassium Fulvate Water Soluble Powder:
1. High-Efficiency Organic Potassium Fertilizer and Biostimulant: Potassium Fulvate Water Soluble Powder provides readily available potassium and contains active groups such as carboxyl/phenolic hydroxyl groups, which can stimulate root development (increasing root length and root hairs by 20%–30%), enhance photosynthesis, and improve stress resistance (drought resistance, cold resistance, and disease resistance).
2. Soil Conditioner: Potassium Fulvate Water Soluble Powder promotes soil aggregate formation (aggregate increase of 20%–30%), improving porosity, aeration, water permeability, and cation exchange capacity; its black color helps absorb heat, facilitating early spring soil temperature rise.
3. Fertilizer Enhancer: Potassium Fulvate Water Soluble Powder reduces nitrogen volatilization and phosphorus fixation through ion exchange/complexation, increasing nitrogen fertilizer utilization by 10%–15% and phosphorus fertilizer utilization by 15%–20%; it is often compounded with nitrogen, phosphorus, potassium, or trace elements to create water-soluble fertilizers.
Application methods of Potassium Fulvate Water Soluble Powder:
1. Seed soaking/root dipping: Soak seeds/roots in a 0.05% solution for 10–24 hours (shorten the time in high temperatures);
2. Foliar spraying: Apply a 0.05% solution (approximately 2000 times dilution) 4–5 times from seedling stage to fruiting stage;
3. Fertigation/drip irrigation: Apply 0.5–1 kg per acre per application, diluted in 20 kg of water, or adjust according to crop type (5 kg/acre for solanaceous crops, 10 kg/acre for fruit trees, and 3 kg/acre for field crops/leafy vegetables);

Advantages of Fulvic Acid:
1. Improve Nutrient Absorption
Fulvic acid reacts with mineral elements in the soil to form nutrient forms that are easily absorbed by crops. This not only increases the availability of soil nutrients but also promotes crop absorption of key nutrients such as nitrogen, phosphorus, and potassium. Therefore, the use of fulvic acid can significantly improve nutrient utilization efficiency in crops, laying the foundation for high yields and quality.
2. Enhance Crop Stress Resistance
Fulvic acid has a potent biostimulant effect, inducing stress resistance in crops. Under adverse conditions such as drought, high temperatures, and low temperatures, fulvic acid helps crops maintain normal physiological functions and mitigates damage caused by these conditions. It also enhances crop disease resistance and reduces the occurrence of pests and diseases, thereby ensuring healthy crop growth.
3. Improve the Soil Environment
Fulvic acid has a beneficial soil conditioning effect, increasing soil organic matter content and improving soil water and nutrient retention. Furthermore, it promotes the growth and activity of soil microorganisms, improving the soil microbial flora and creating a favorable soil environment for crop growth. These effects help improve soil fertility and create conditions for sustained high crop yields.
