FAQ
1. Why choose Mineral Source Potassium Fulvate Powder Ι over flakes for liquid fertilizer production?
Our powder has 80-100mesh fineness and higher bulk density—saves shipping costs, dissolves faster (with proper stirring), and mixes evenly into liquid formulations. European and Asian liquid fertilizer makers prefer it!
2. Will it clump in dissolution? How to avoid it?
Only if you add water to powder! Always add powder to water and stir promptly—no clumping. Customers in Southeast Asia (humid climates) have used it smoothly for years.
3. Works in hard water areas like the Middle East?
Absolutely! Flocculation limit 350mg CaO/L—most Middle Eastern hard water has Ca²⁺ ≤300mg/L, so no flocculation or drip irrigation clogging.
4. Can I mix it with acidic pesticides or chelated microelements?
Yes! Small molecular structure ensures compatibility—no precipitation with acidic/alkaline products. Used by farmers in Africa and South America for mixed applications.
5. Lignite-sourced vs. biochemical (molasses/paper waste) products—what’s better?
Lignite-sourced has higher activity and stable properties—effects last 4-6 weeks in soil (twice as long as biochemical ones). Perfect for long-term soil improvement in North America and Europe.
6. Suitable for granular fertilizer blending?
Absolutely! 80-100mesh fineness mixes evenly with NPK powders—Indian, Pakistani, and Turkish fertilizer producers use it for functional granular products.
7. pH is 9-10—will it conflict with acidic fertilizers?
No! The small-molecule fulvic acid buffers pH, stabilizing the blend and boosting nutrient availability. Used widely in acidic soil areas of Southeast Asia.
8. Minimum order quantity (MOQ) and packaging options?
MOQ is 10kg—packaging includes 1kg, 5kg, 25kg bags, or jumbo bags. Custom packaging available for all regions, with fast delivery (3-7 days to Southeast Asia, 7-12 days to Europe/North America).
