Potassium fulvate instant powder is produced from refined lignite sources rich in natural fulvic acid. The manufacturing process begins with crushing the raw material, which is then treated with a potassium hydroxide solution. After the reaction is complete, the mixture undergoes centrifugation to isolate a liquid concentrate, while the residual solids are repurposed for granular products.
This liquid concentrate is further refined using multi-stage evaporation to achieve optimal concentration. It is then processed in a spray dryer equipped with centrifugal atomization, transforming the solution into fine droplets that are instantly dried upon contact with heated air.
Preserving a higher level of bioactive compounds compared to flake or conventional powder variants. The final product is characterized by its consistent particle size, rapid dissolution, and elevated fulvic acid content, making it particularly suitable for high-quality water-soluble fertilizers and formulations requiring uniform dispersion and appearance.
(1) Optimize Soil Health & Boost Fertility
Strengthens soil aggregation, improving moisture retention and nutrient-holding capacity. Reduces compaction and salinity, while stimulating microbial activity (bacteria and actinomycetes) to enhance nutrient conversion in the soil.
(2) Stimulate Root Development & Increase Stress Tolerance
Promotes robust root growth—elongating main roots and increasing lateral root formation—to improve water and nutrient uptake. Enhances natural resistance to drought, cold, pests, and diseases through improved metabolic regulation.
(3) Enhance Nutrient Availability & Fertilizer Efficiency
Chelates locked nutrients in the soil (e.g., calcium, magnesium, iron), increasing their availability to plants. When blended with chemical fertilizers, it reduces nutrient loss and raises utilization efficiency by 15–30%.
(4) Elevate Crop Yield & Quality
Supports flowering and fruit development, improves sugar content (e.g., raising brix levels by 1–2 degrees) and coloration. Redrates malformed fruits, extends shelf life, and typically increases overall yield by 10–20%.

(1) Foliar Spray
Dilution: 1000–1500x (1g per 1–1.5L water)
Rate: 750–1200g/ha per application, in 750–1500L water
Timing: Spray at seedling, jointing, and booting stages; 10–15 days between sprays
Note: Avoid spraying during fruit set to prevent residue on fruits.
(2) Drip Irrigation / Fertigation
Rate: 1.5–3kg/ha per application, applied with irrigation water
Timing: Apply during seedling and active growth stages; avoid peak flowering.
(3) Seed Treatment
Soaking: Dilute 500x; soak seeds 4–6 hours before sowing to improve germination
Coating: Use 2–3g product per 1kg seeds; mix thoroughly before sowing
Apply before 9 AM or after 4 PM on sunny days. Avoid midday heat and intense sunlight to prevent rapid evaporation.
Compatible with most agrochemicals (excluding strong acids/bases). Conduct a pre-mix test before full combination.
Store sealed in a cool, dry area. Moisture may cause clumping, which does not affect efficacy—crush before use if needed.
