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 Magnesium supplies 10% magnesium (Mg, as part of 10%+ Ca+Mg) carried by 21.54% fulvic acid, with 3.48% K₂O and 13.95% sulfur for a broad secondary-nutrient package. Water-insoluble matter is just 0.18% — no blockage in any system.
Magnesium is the central atom of chlorophyll; deficiency shows as interveinal yellowing of older leaves, leaf curling and low photosynthesis. Fulvic acid chelates the Mg and carries it into the plant, correcting the disorder that ordinary magnesium sulphate fixes slowly. Heavy-metal indicators are far below standard (Pb, Hg, Cr not detected), so it is safe for crops, soil and environment.
Uniform powder, low moisture (2.59%), no caking. Use it in drip, foliar, seed treatment and soil application across fruit, vegetable, grain and cash crops.
Key Benefits
10% magnesium (as Ca+Mg ≥10%)
Mg is the core of chlorophyll; fulvic chelation carries it into the plant fast.

A broad secondary-nutrient package, not just Mg.
0.18% water-insoluble
No blockage; suitable for drip, sprinkler and foliar.
Corrects Mg deficiency
The grade for interveinal yellowing of older leaves, curling and low photosynthesis.
High safety
Heavy metals (Pb, Hg, Cr) not detected; safe for crops and soil.

Form & Solubility
Form: uniform brown powder, low moisture (2.59%), free-flowing, no caking.
In water: dissolves completely with no residue; suitable for drip, sprinkler and foliar.
Best practice: foliar at 1000–1500× in morning/evening; drip at 800–1200×. Do not mix with strong acid/alkali; jar-test before blending. If rain within 4 h, rinse and re-spray.
Storage: cool, dry, ventilated; seal tightly. Shelf life 24 months.

Frequently Asked Questions
Why fulvic-chelated magnesium?
Mg is the core of chlorophyll but is easily fixed in soil; fulvic acid chelates it and carries it into the plant, correcting interveinal yellowing faster than straight sulphate.
Can it be used during flowering?
Yes. At 1000–1500× foliar it does not affect pollination and strengthens flower organs, reducing flower/fruit drop.
Is it suitable for organic farming?
Made from quality raw materials, free of harmful chemicals and heavy metals (Pb, Hg, Cr not detected); meets relevant organic-input standards. Confirm your body at enquiry.
Is it compatible with other inputs?
Mixes with most neutral/acidic fertilizers and pesticides; not with strong acid/alkali. 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 — Mg, fulvic acid, K₂O, S, moisture and pH tested to HG/T and NY/T methods.
