JINGFENG®’s Mineral Source Potassium Fulvate Flakes Ι is a high-activity bio-stimulant derived from premium Young Leonardite. Unlike standard humic products, it features a low molecular weight and an advanced purification process that ensures 100% instant solubility.
The definitive competitive advantage of our FlakesⅠis its Universal Compatibility. It is specifically engineered to be mixed with NPK fertilizers, chelated micro-elements, pesticides, and hormones without any precipitation or flocculation, making it the perfect base for high-end liquid formulations.

▶️Case 1: African Desert Soil Reclamation & AI-Driven Solutions
Customer Profile: A large-scale environmental project in Africa focused on desert soil restoration.
The Challenge: The client needed a high-activity organic stimulant that could remain stable in extreme soil temperatures and integrate with complex reclamation formulas.
Our Solution: Using our 2026 AI Technical Assistant, we analyzed the desert soil data and provided a customized application plan centered on Potassium Fulvate Flakes Ⅰ (JFHA-FA-F/P).
The Result: Our AI successfully planned the technical negotiation and provided solutions that met the project’s strict standards. The project is currently in the product registration stage, with our FlakesⅠserving as the core bio-stimulant for enhancing nutrient retention in sandy soils.
▶️Case 2: Liquid Fertilizer Compatibility Success (Europe)
Customer Profile: A premium liquid fertilizer manufacturer specializing in NPK + Trace Element blends.
The Challenge: The client struggled with precipitation when mixing traditional humic acids with chelated zinc and manganese, leading to “sludge” at the bottom of their storage tanks.
Our Solution: They switched to our Mineral Source Flakes Ⅰ due to its low molecular weight and high compatibility.
The Result: Zero precipitation. Even after 6 months of storage, the liquid blend remained a stable, clear solution. This allowed the client to market their product as a “premium, clog-free formulation,” increasing their retail price by 12%.
▶️Overcoming High-Salinity Irrigation (Middle East)
Customer Profile: A high-tech greenhouse facility using hard well water for drip irrigation.
The Challenge: Standard potassium humate would immediately flocculate and clog drip emitters when meeting the $300\text{mg/L}$ calcium concentration in their water source.
Our Solution: We deployed Flakes Ⅰ, highlighting its Flocculation Limit of 350mg CaO/L
The Result: The irrigation system maintained perfect pressure throughout the 4-month growing season. The client reported a 20% reduction in labor costs previously spent on cleaning clogged nozzles and acid-washing the system.
💬Q1: What is the difference between Mineral Source and Biochemical Potassium Fulvate?
✅Our product is derived from high-grade young Leonardite (Mineral Source), which offers higher biological activity, more stable chemical properties, and longer-lasting effects in the soil compared to biochemical versions made from molasses or paper waste.
💬Q2: Can I mix this Potassium Fulvate with acidic pesticides or fertilizers?
✅Yes. Due to its low molecular weight and high activity, JFHA-FA-F/P shows excellent compatibility. Unlike standard potassium humate, it can be mixed with most macro/micro-element fertilizers and pesticides without causing precipitation.
💬Q3: Does this product cause clogging in drip irrigation systems?
✅No. It features 100% water solubility and a high Flocculation Limit Value (350mg CaO/L). This means it remains fully dissolved even in hard water areas, ensuring a smooth, clog-free performance for all irrigation equipment.
💬Q4: Why is “Low Molecular Weight” important for my crops?
✅Low molecular weight means the fulvic acid molecules are smaller and more “agile,” allowing them to penetrate plant cell membranes more easily. This leads to faster nutrient absorption and quicker visible results after application.
💬Q5: Is your Potassium Fulvate certified for organic farming?
✅Yes, our company has secured CERES certification for amino acids and seaweed extracts, and we maintain high-quality standards across our mineral source lines to meet international agricultural requirements.
💬Q6. Can this product be used for foliar spraying?
✅ Absolutely. Because of its high purity and instant solubility, it is ideal for foliar application. It acts as a natural carrier, helping the plant absorb other nutrients and hormones mixed in the tank more efficiently.
💬7. How does this product handle high-calcium (hard) water?
✅ It is specifically designed for hard water resistance. With a resistance value of 350mg CaO/L, it prevents the “salting out” effect commonly seen when humic products meet calcium or magnesium ions in the water.
💬Q8: What is the potassium (K2O) content in your Mineral Source Potassium Fulvate Flakes Ι ?
✅Our Flakes Ⅰ contains a minimum of 12.0% Potassium (K2O on a dry basis), providing an essential boost of available potassium to help with fruit sizing, coloring, and overall plant turgor. The highest K2O content we can produce is 18%min.
💬Q9: Do you have EU REACH registration for this product?
✅As part of our 2025 milestones, we have successfully obtained the EU REACH registration for Potassium Humate, facilitating easier customs clearance and trade for our European partners.
💬Q10: Can I mix this product with acidic pesticides? ?
✅Yes, Flakes Ⅰ is designed for high compatibility. While the product is alkaline (pH 9-10), its small molecular structure allows it to coexist with most agricultural chemicals. Always recommend a jar test for sensitive formulas.
💬Q11: 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.
