What Our Clients Say
Ultimate FAQ Guide to Fulvic Acid Flakes
What makes fulvic acid flakes different from regular humic acid?
Fulvic acid flakes are low molecular weight, water-soluble, and biologically active, unlike humic acid which is heavier and partially soluble. Their small molecules enhance nutrient chelation, improve soil absorption, and are more easily taken up by plants, leading to better growth and higher crop yield.
How should I apply fulvic acid flakes to crops?
Fulvic acid flakes can be applied via foliar spray, drip irrigation, water flushing, or seed treatment. Recommended dosages vary by crop type, generally 0.5–2 kg/ha for irrigation and 0.6–2.5 kg/ha for foliar sprays. Always dissolve fully in water before application for optimal results.
Can fulvic acid flakes be mixed with other fertilizers and pesticides?
Yes, they are compatible with NPK fertilizers, micronutrients, herbicides, and fungicides. However, a miscibility test is recommended before large-scale mixing to ensure no precipitation occurs and to maintain full efficacy.
What soil or crop conditions benefit most from fulvic acid flakes?
Crops grown in sandy, clay, or nutrient-deficient soils benefit most. fulvic acid flakes improve soil structure, water retention, nutrient availability, and microbial activity, helping plants better resist drought, salinity, cold, and pests while promoting healthier root systems.
How should fulvic acid flakes be stored for long-term use?
Store in a dry, clean, dark, and well-ventilated area. Keep in original sealed containers to prevent moisture absorption. Under proper conditions, fulvic acid flakes maintain their physical, chemical, and biological properties for at least 3 years.
What is the ideal concentration for liquid fertilizer production using fulvic acid flakes?
For liquid fertilizers, 5–10% fulvic acid flakes by weight is typical. They dissolve fully and maintain low viscosity, making them suitable for high-concentration liquid fertilizer production and fertigation systems, enhancing nutrient uptake efficiency and crop growth.
Are fulvic acid flakes safe for all types of crops?
Yes, they are safe for vegetables, fruits, field crops, turf, hydroponics, and seed treatment. Their natural organic composition improves plant health and soil biology without toxicity, heavy metals, or residues that could harm crops or soil ecosystems.
