Product Description:
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.
Main functions:
(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%.

Usage method:
(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
Precautions:
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.
