Product Overview
Bio Fulvic Acid is JINGFENG’s biotech-fermented fulvic acid — produced by microbial fermentation of plant-derived feedstock rather than mined from leonardite. It is a short-chain humic substance rich in fulvic acid, free amino acids, enzymes, sugars and trace nutrients. Fully water soluble and hormone-free, it is used worldwide as a fertilizer raw material and plant biostimulant — chelating nutrients, buffering soil pH, and improving nutrient uptake in foliar, fertigation and blending programmes.
Bio Fulvic Acid Chelate Iron is a high-performance water-soluble fertilizer built to correct iron deficiency fast. It delivers 14% iron (Fe) carried by 15% fulvic acid, with 0% water-insoluble matter so nothing blocks your pipes.
Iron is the classic immobile micronutrient: deficiency shows as interveinal chlorosis of young leaves (yellow between green veins), and it hits calcareous and alkaline soils hardest — apple, pear, grape, citrus, tomato, peanut and wheat are all sensitive. Fulvic acid chelates the iron and carries it into the leaf, correcting chlorosis that ordinary iron sulphate cannot.
Low moisture (2.9%), uniform powder, no caking; harmless to crops, soil and environment and compliant with strict agricultural standards. Use it in drip, foliar and seed treatments across fruit, vegetable, grain, cash and oil crops.

Frequently Asked Questions
How does fulvic-chelated iron correct chlorosis?
Fulvic acid chelates the Fe and carries it into the leaf, bypassing the soil fixation that makes ordinary iron sulphate useless on calcareous ground. Chlorosis clears within 1–2 applications.
Which crops are most sensitive?
Apple, pear, grape, citrus, strawberry, tomato, wheat, tea and peanut — especially on alkaline or calcareous soils.
Can it be used during flowering?
Yes. At the recommended dilution it does not affect pollination; it strengthens flower organs and improves fruit set.
Is it compatible with other inputs?
Mixes with most neutral/acidic fertilizers and pesticides; not with strong alkaline products. Jar-test first.
What is the shelf life?
24 months from production date under proper storage. Seal tightly after use.
Do you provide a COA per batch?
Yes — Fe, fulvic acid, moisture and pH tested to HG/T and NY/T methods.
