Code JFHA-NaHA-F40
Every lot ships with a Certificate of Analysis stating actual tested values.
Product Overview
Sodium Humate is the sodium salt of humic acid, produced by alkaline extraction of leonardite-sourced humic acid. The sodium form is highly water soluble, so it dissolves completely and goes to work fast. It is used worldwide as a soil conditioner and nutrient chelate in agriculture, a water-purifying and immunity aid in aquaculture and animal feed, and a binder in drilling fluids and ceramics.
40% Sodium Humate Big Flakes carries 40% humic acid on a dry basis with 90% water solubility and a low dust flake form. The large flakes wet out and disperse quickly, so they are easy to dissolve for liquid use yet cleaner to handle than powder.
Choose this grade when you want faster dissolution than the granule but still low dust at the hopper — for liquid humate production, pond treatment and blends where a 40% humic guarantee is the target.
Key Benefits
40% humic acid
A mid-range humic guarantee for soil, feed and aquaculture use.
90% water soluble
Dissolves quickly with only a small residue — good for liquid humate and pond use.
Low-dust flakes
Big flakes handle cleaner than powder at the intake.
Fast wetting
Wets out and disperses in seconds under light agitation.
Multi-use
Soil conditioner, feed additive and aquaculture water-purifying aid.
COA on every batch
Each lot ships with a Certificate of Analysis stating tested humic acid, solubility and pH.

Form & Solubility
Form: black big flakes, low-dust and free-flowing. Large surface area means fast wetting.
In water: wets out on contact and disperses within seconds under light agitation. Add onto moving water to avoid a surface crust.
Handling: low dust, but standard PPE recommended during bulk handling.
How the sodium humate grades compare
| Grade | Form | Humic acid | Water solubility | Moisture | Best for |
|---|---|---|---|---|---|
| 30% Sodium Humate Round Granule | Granule | ≥ 30% | ≥ 70% | ≤ 20% | Dust-free blend & broadcast |
| 40% Sodium Humate Big Flakes (this product) | Flakes | ≥ 40% | ≥ 90% | ≤ 15% | Fast-dissolve low-dust flake |
| 50-60% Sodium Humate Big Shiny Flakes | Shiny flakes | ≥ 50% | 100% | — | Fully soluble premium flake |
| 50-60% Sodium Humate Powder | Powder | ≥ 50% | ≥ 85% | ≤ 15% | Fast-dissolve blender powder |
| 60% Sodium Humate Crystal | Crystal | ≥ 60% | ≥ 99% | — | High-active near-soluble crystal |
| 60-70% Sodium Humate Flakes | Flakes | ≥ 65% | 100% | ≤ 13% | Top fully-soluble flake |
| 60-70% Sodium Humate Powder | Powder | ≥ 60% | ≥ 99% | ≤ 15% | High-active blender powder |
Higher humic % means more active per kilo; solubility and form decide handling and dissolution. All grades are alkaline (pH 9–10).
Applications & Dosage
Used in agriculture, aquaculture water treatment and as a feed/industry input.
| Application | How to use | Rate |
|---|---|---|
| Liquid humate production | Dissolve to make a working sodium humate solution for fertigation or foliar. | As required |
| Aquaculture water | Dissolve and spread in ponds to bind ammonia and clarify water. | 1–2 kg/1000 m³ |
| Soil / blend | Blend into fertilizer or broadcast before planting. | 15–30 kg/ha |
| Animal feed additive | Mix into feed per species guideline. | Per formula |
Packaging & Storage
| Pack size | Description |
|---|---|
| 25 kg | Woven bag with inner PE liner |
| 1000–1100 kg | Jumbo bag with discharge spout |
Storage: Store in a cool, dry, well-ventilated place. The flakes are stable for 2 years; reseal opened bags to keep moisture low.

Frequently Asked Questions
Flakes or powder?
Flakes dissolve fast and dust less; powder dissolves fastest and blends finest. Pick flakes when dust control matters.
Is it fully soluble?
Around 90% on a dry basis — a small residue is normal. Pre-dissolve and filter for a clear solution.
Can it go in ponds?
Yes — dissolve and spread; it binds ammonia and clarifies water. Dose by pond volume.
What is the organic matter content?
≥ 70% on a dry basis alongside the 40% humic acid guarantee.
Do you provide a COA per batch?
Yes — tested humic acid, organic matter, solubility, moisture and pH.
What is the minimum order and lead time?
Stock item. MOQ one pallet; 7–15 days ex-works. Private-label printing available.
