Biochemical Fulvic Acid 95% Powder (Plant-Derived)
Corn Stalk Source Biochemical Fulvic Acid
NovaFul is a plant-derived biochemical fulvic acid 95% powder extracted from corn stalks by biological fermentation. It works as a natural chelating agent, soil conditioner and stress tolerance booster, improving nutrient uptake, soil structure and fertilizer efficiency while stimulating root development and resilience to drought and salinity. For field use: foliar spray 150–300 g/ha (dilute 1:3,000–1:5,000 in water, approx. 20–30 g per 100 L) every 10–14 days; fertigation 1.0–3.0 kg/ha per application (3–4 times per crop cycle); seed soaking at 1:800–1:1,000 for 8–12 hours. For formulators: add 5–15% (w/v) into liquid biostimulant concentrates or 2–10% (w/w) into water-soluble NPK and micronutrient blends. Packed in 25 kg bags with custom OEM packaging. MOQ 1,000 kg; standard lead time approximately 10 working days to Shanghai port; batch COA with every shipment.

Key benefits
- 100% Plant-Derived & Sustainable Source (Corn Stalk Bio-Fulvic): Sourced entirely from renewable corn stalk biomass via advanced biological fermentation, guaranteeing a clean-label, eco-friendly plant-origin bio-fulvic acid powder free from heavy metals, sodium salts, and coal-derived impurities.
- Ultra-High Purity & Bioactivity (95% Fulvic Acid Content): Features an exceptional 95% fulvic acid concentration with ultra-low molecular weight, allowing instant cellular membrane penetration and maximum bio-availability compared to traditional lignite or leonardite potassium humate.
- 100% Water Solubility & Broad pH Stability (pH 1–14 Compliant): Fully soluble in water with zero precipitation. Demonstrates extreme acid tolerance and hard water resistance, making it perfectly compatible with low pH liquid fertilizers, acidic pesticides, and trace element tank mixes without clogging nozzles.
- Superior Micronutrient Chelation & Uptake Booster: Rich in carboxyl and phenolic hydroxyl functional groups that naturally chelate trace elements (Fe2+, Zn2+, Mn2+, Cu2+, Ca2+). It prevents nutrient fixation in alkaline soil and enhances root uptake efficiency.
- Drought Resistance & Osmotic Regulation: Acts as a powerful plant osmoprotectant and stress reducer. It regulates stomatal opening to decrease transpiration losses, enhances root elongation, and aids crop recovery after drought, heat waves, salinity, or chemical phytotoxicity.
- Soil Structure Improvement & Microbial Stimulant: Promotes soil aggregate formation, increases cation exchange capacity (CEC), and serves as a carbon source to stimulate beneficial soil microflora.
- Factory Direct Bulk Supply & OEM Customization: Sourced directly from a leading China bio-fulvic acid factory, available in 20kg/25kg craft paper bags, custom big bags, and complete technical dossiers (COA, MSDS) for global registration.
Suggested dosage & application
For Formulators & Fertilizer Manufacturers (Industrial Blending & Tank Mixes)
- Liquid Biostimulants & Foliar Concentrates: Blend 50 kg – 150 kg of Corn Stalk Fulvic Acid 95% Powder per 1,000 Liters of water (5.0% – 15.0% w/v) to formulate high-concentration organic liquid biostimulants.
- Water-Soluble NPK & Micronutrient Fertilizers: Incorporate 20 kg – 100 kg per Metric Ton (2.0% – 10.0% w/w) into WS-NPK or trace element formulations as a natural organic chelator and root stimulant.
- Liquid Chelated Trace Element Blends (Fe/Zn/Mn/Ca): Dissolve 100 kg – 200 kg per 1,000 Liters together with inorganic micronutrient salts to produce stable, fully chelated liquid micronutrient fertilizers.
- OEM Customization: Private labeling, custom bag sizing, and batch COA support.
For Commercial Field Application (End-Users & Agronomists)
- Foliar Spraying (Crop Stress & Growth Boost): Apply 150–300 g/ha (dilution 1:3,000 to 1:5,000 in water; approx. 20–30 g per 100 L water). Apply every 10–14 days during early vegetative growth, pre-flowering, or immediately after drought, heat, or frost stress.
- Drip Irrigation & Fertigation: Apply 1.0–3.0 kg/ha through fertigation systems during root initiation, seedling establishment, or fruit swelling to improve soil CEC and nutrient absorption.
- Seed Treatment & Root Dipping: Use 0.5–1.0 g per Liter of water (1:1,000 dilution) for seed soaking or root dipping to reduce transplant shock, increase seed germination speed, and stimulate early root branching.

Frequently asked questions
01What is the difference between corn stalk bio-fulvic acid 95% and traditional leonardite fulvic acid?
Corn stalk bio-fulvic acid 95% is a 100% plant-derived biostimulant produced via biological fermentation of renewable agricultural biomass. Compared to mineral/leonardite fulvic acid, bio-fulvic acid features a significantly lower molecular weight, higher biological activity, superior cold water solubility, and complete acid resistance across pH 1 to 14 without precipitation.
02Is 95% corn stalk fulvic acid powder compatible with acidic fertilizers and trace elements in tank mixes?
Yes. Unlike mineral potassium humate which precipitates in acidic solutions, corn stalk bio-fulvic acid 95% powder exhibits outstanding hard water and acid stability (pH 1–14 compliant). It can be safely tank-mixed with amino acids, seaweed extracts, NPKs, acidic pesticides, and chelated micronutrients (Fe2+, Zn2+, Mn2+, Ca2+) without clogging nozzles.
03How does bio-fulvic acid 95% act as a natural micronutrient chelator and biostimulant?
Rich in carboxyl and phenolic hydroxyl functional groups, bio-fulvic acid 95% naturally complexes with trace elements in the soil, preventing phosphate fixation and nutrient leaching. As a biostimulant, it regulates stomatal conductance to reduce transpiration during drought, accelerates chlorophyll synthesis, and increases root biomass.
04What is the recommended dosage of bio-fulvic acid 95% powder for foliar spray and fertigation?
For foliar spraying, the standard application rate is 150 g to 300 g per hectare (diluted 1:3,000 to 1:5,000 with water). For drip irrigation and fertigation, apply 1.0 kg to 3.0 kg per hectare per application to stimulate root development and enhance soil CEC.
05What is the MOQ, packaging and lead time for NovaFul fulvic acid 95% powder?
NovaFul fulvic acid 95% powder is packed in standard export packaging 25 kg/bag with OEM customization available. MOQ is 1,000 kg; lead time is about 10 working days to Shanghai port, and every shipment includes a batch COA.
06How should NovaFul fulvic acid 95% powder be stored?
Store sealed in a cool, dry place below 25 °C, away from direct sunlight and moisture. Shelf life is 24 months from the manufacturing date; keep the packaging tightly closed after use.
