Product Detail

Fulvic Acid

Water-soluble fulvic acid powder in ≥50% and ≥90% grades, CAS 479-66-3, a mineral- or biochemical-source biostimulant and chelating carrier. Values are industry-typical and confirmed per batch COA.

What it is / When to use

Water-soluble biostimulant and chelating carrier

Fulvic Acid is a water-soluble organic-material powder, CAS 479-66-3, supplied in ≥50% and ≥90% fulvic acid grades from mineral or biochemical sources. RunziChem exports it as a biostimulant and chelating carrier that supports nutrient uptake, phosphate and potassium availability, and drought tolerance.

  • What it is Fulvic acid, CAS 479-66-3, a yellow-brown to dark-brown water-soluble powder in ≥50% and ≥90% grades.
  • When to use Use it as a biostimulant and chelating carrier in water-soluble fertilizers, drip and foliar programs, and micronutrient or NPK blends where improved uptake and stress tolerance are needed.

Applications

Where Fulvic Acid fits

Confirm crop, rate, compatibility, and local label requirements before application.

Nutrient chelation

Fulvic acid chelates and mobilises micronutrients, helping keep iron, zinc, and manganese available to the crop.

Phosphate & potassium release

Supports phosphate and potassium availability in soil, improving the efficiency of applied P and K.

Drought & stress tolerance

Used to strengthen root activity and abiotic-stress tolerance, including drought conditions.

≥50% and ≥90% grades

An economical ≥50% blending grade and a high-purity ≥90% grade for concentrated formulas; exact assay confirmed per inquiry.

Blend carrier

A fully water-soluble carrier for water-soluble fertilizer, drip, and foliar production alongside amino acid and NPK.

Buyer FAQ

Fulvic Acid questions

What is the difference between the ≥50% and ≥90% fulvic acid grades?
Both grades are water-soluble fulvic acid powders; they differ in fulvic acid concentration. The ≥50% grade is an economical biostimulant and blending carrier, while the ≥90% grade is a high-purity fulvic acid for concentrated foliar and fertigation formulas. These are industry-typical values for Fulvic Acid, and the exact assay is confirmed per inquiry and per batch COA.
Should I choose fulvic acid or amino acid as a biostimulant carrier?
Fulvic Acid is a small-molecule organic acid (CAS 479-66-3) that chelates nutrients, improves phosphate and potassium availability, and boosts drought tolerance, making it a strong carrier for micronutrient and NPK blends. Amino Acid delivers free amino acids and organic nitrogen as a direct biostimulant. Many programs combine both; RunziChem can supply either or a co-formulated blend on request.
Is RunziChem fulvic acid water-soluble and suitable for drip and foliar use?
Yes. RunziChem Fulvic Acid is supplied as a fully water-soluble yellow-brown to dark-brown powder in ≥50% and ≥90% grades. It dissolves for drip irrigation, foliar spraying, and water-soluble fertilizer production. Source (mineral or biochemical/fermentation), grade, and screen size are confirmed per inquiry.
Are the fulvic acid content and CAS values guaranteed?
No. The figures shown for Fulvic Acid, such as ≥50% or ≥90% fulvic acid and CAS 479-66-3, are industry-typical or commonly cited reference values for buyer screening. The current batch certificate of analysis (COA) confirms the final fulvic acid content, moisture, water-solubility, and appearance for the lot you receive.
