Product Overview
JINGFENG®’sMineral Source Potassium Fulvate Micro Granule Ιis crafted via spray-drying technology, featuring a unique hollow structure and ~0.3mm uniform particle size.
It solves the core pain points of powder (easy clumping) and flakes (slow dissolution) – dissolves instantly in water without stirring, no lumps, and delivers efficient nutrient absorption for all fertilizer production and application scenarios!
Key Benefits
1. Hollow Structure + Spray-Drying = No Clumping & Fast Dissolution
- The spray-drying process creates a porous hollow interior – when in contact with water, moisture penetrates the granule from all sides, dissolving it completely in 10-15 seconds.
- No more lumps from powder “floating on water” or slow dissolution from dense flakes.
2. Dust-Free & Easy to Handle
- 0.5mm micro granules eliminate the dust pollution of powder during production and application, protecting workers’ health and reducing material waste.
- It’s also free-flowing, making it easy to blend with other fertilizers in automated production lines.
- High-efficiency liquid fertilizer production: Saves stirring time, shortens batch production cycles by 40%.
- Mechanized fertilization: Compatible with precision seeding/fertilizing equipment, ideal for large-scale farms.

Successful Cases
CaseEuropean Liquid Fertilizer Factory – Production Efficiency Upgrade
French manufacturer of high-end foliar fertilizers. Challenge: Powder potassium fulvate caused clumping in mixing tanks, requiring extra stirring time and cleaning. Solution: Switched to our micro granule (7% addition ratio) – no pre-stirring needed. Results: Batch production time cut by 40% (from 30 mins to 18 mins); zero clumping-related downtime; product stability extended to 8 months.
CaseNorth American Large-Scale Corn Farm (1000ha)
Iowa-based mechanized farm using precision drip irrigation. Challenge: Flakes dissolved too slowly, leading to uneven nutrient distribution; powder clumped in irrigation lines. Solution: Adopted micro granule (4kg/ha) – direct addition to irrigation systems. Results: Instant dissolution ensured uniform fertilization; corn yield increased by 12%; irrigation line cleaning frequency reduced from monthly to quarterly.
CaseSoutheast Asian Greenhouse Cluster (Vegetables)
80-hectare tomato/cucumber greenhouses in Thailand, using manual irrigation. Challenge: Farmers struggled with powder clumping (no professional stirring equipment); flakes took too long to dissolve. Solution: Recommended micro granule – added directly to watering cans. Results: No clumping even with hand mixing; nutrient absorption rate improved by 25%; farmer labor time reduced by 30%.
FAQ
1. How much faster does the micro granule dissolve compared to flakes?
10x faster! Flakes take 30+ minutes, while our micro granule dissolves in 10-15 seconds – perfect for time-sensitive production or manual irrigation in Southeast Asia.
2. Does it really not clump at all, even without stirring?
Exactly! The hollow spray-dried structure lets water penetrate instantly – no surface tension issues like powder. Farmers in Africa and Latin America use it in hand watering cans with zero clumping.
3. Is it suitable for hard water areas like the Middle East?
Yes! Flocculation limit 350mg CaO/L – most Middle Eastern hard water has Ca²⁺ ≤300mg/L, so no flocculation or drip emitter clogging.
4. How does it perform in cold water (e.g., Northern Europe)?
Dissolves equally fast in 10-30℃ water – no heating required, unlike flakes that need warm water for faster dissolution.
5. Can it be blended with granular NPK for mechanized broadcasting?
Absolutely! Free-flowing micro granules mix evenly with NPK, no segregation – used by large farms in North America and Australia for precision fertilization.
6. Do you have export certifications (EU REACH, US EPA)?
Yes! Full certification package for global export – smooth customs clearance to Europe, US, Japan, and Southeast Asia.
7. How does it compare to powder in terms of storage?
Better anti-caking! Micro granules resist moisture absorption more than powder – store in dry conditions for 24 months with zero caking, ideal for humid regions like Southeast Asia.
8. Minimum order quantity (MOQ) and packaging options?
MOQ 1000kg – packaging includes 1kg, 5kg, 25kg bags, or jumbo bags. Custom packaging available for all regions.
9. Does JINGFENG provide logistics support for this high-spec product?
Yes. As per our 2026 strategy, we have optimized our Logistics & Documents Team to handle strict inspections. Combined with our EU REACH and CERES certifications, we ensure smooth and fast delivery to global markets.
