Stimulates Growth of Crop Roots Potassium Fulvate Powder for Root
Promotion and Efficiency Enhancement pH 9-11
Product Description:
Our mineral-sourced potassium fulvic acid is extracted from
high-quality lignite and weathered coal. Through a precise
manufacturing process—where potassium hydroxide is introduced into
raw fulvic acid solution, followed by drum-drying, flaking, and
fine grinding with a Raymond mill—we produce a highly soluble,
chemically stable powder.
Unlike bio-fermented fulvic acid, our mineral-based product
delivers superior performance in challenging agronomic conditions:
Ideal for degraded soils: alleviates compaction, reduces salinity,
and restores nutrient balance
Enhances stress tolerance in high-demand crops: fruit trees,
greenhouse vegetables, and arid-region farming
Excellent as a base fertilizer for long-term soil health
improvement
This mineral-derived powder is versatile in application:
✔️ Fully water-soluble – suitable for foliar spray with fine
particle size and strong adhesion
✔️ Compatible with fertilizers and agrochemicals – mixes evenly
without clogging or settling
✔️ Promotes soil structure and microbial activity – increases
fertilizer efficiency and drought resistance

Usage method:
(1) Foliar Spray
Quick-absorption nutrition suitable for all crop growth stages.
Method: Dissolve powder in water at 0.05%–0.1% concentration. Spray
evenly on both sides of leaves.
Rate: 750–1500 g/ha per application, diluted in 450–750 kg water.
Schedule: Apply every 7–15 days during growth. Spray before
expected stress (drought, cold) to improve resilience.
(2) Drip Irrigation / Flush Application
Efficient nutrient delivery directly to the root zone.
Method: Pre-dissolve in warm water to prevent lumps, then dilute
for irrigation systems.
Dosage:
Fruit trees (e.g., citrus, apple): 3–4.5 kg/ha every 20–30 days.
Vegetables (e.g., tomato, cucumber): 1.5–3 kg/ha; reduce rate for
seedlings, increase after fruiting.
Field crops (e.g., corn, wheat): 1.5–2.25 kg/ha at jointing and
grain-filling stages.
(3) Fertilizer Mixing / Seed Treatment
Enhance fertilizer efficiency and seed vitality.
Fertilizer Mixing: Blend 1.5–3 kg/mu with compound or organic
fertilizer. Apply as base or topdressing.
Seed Treatment: Use 0.1%–0.2% of seed weight. Mix with water, coat
seeds, shade-dry before sowing.
⚠️ Note: Avoid spraying directly on fruits during fruit-setting to
prevent staining.
Reference dosage for target crops:
1. Fruit Trees (e.g., citrus, apple, grape, kiwi):
Enhances flowering & fruit retention, improves quality (sweetness,
color), reduces replant issues.
2. Vegetables (e.g., tomato, cucumber, pepper, strawberry):
Stimulates root growth in seedlings, increases stress and disease
resistance, improves yield and flavor.
3. Field Crops (e.g., corn, wheat, rice):
Strengthens lodging and drought resistance, raises thousand-grain
weight.
4. Specialty Crops (e.g., cotton, herbs, flowers):
Promotes uniform growth and enhances marketable quality.
Usage Notes
Storage: Keep sealed and dry. If clumping occurs, break and
dissolve—efficacy remains unchanged.
Application: Always pre-dissolve in water. Do not apply dry (causes
dust and re-caking).
Dosage: Follow recommended rates. Excess may lead to overgrowth.
Adjust based on crop needs and soil conditions.
Timing: Best applied during key growth stages (e.g., seedling,
flowering, fruiting) or under stress for optimal results.
