60-70% Sodium Humate Powder
The High-Active Powder — 60% Humic, Blends Fine
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.
60-70% Sodium Humate Powder is the high-active powder grade, guaranteed 60% humic acid on a dry basis with 99% water solubility. It keeps the fast dissolution and uniform blending of powder while raising the humic number to 60% — the blender’s high-active option.
As with the 50-60% powder, the fine grade dusts more than flakes; choose it when fastest dissolution and finest blend uniformity matter most.
Key Benefits
60% humic acid
A high humic guarantee in the fastest-dissolving form.

Form: free-flowing black powder, fine grade. Fastest to dissolve, most uniform to blend.
In water: wets out on contact and disperses within seconds under light agitation. Add onto moving water to avoid a surface crust.
Dust: the fine grade raises dust at the hopper — standard PPE and local extraction recommended.
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 | 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 (this product) | 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
High-active powder for NPK blends and liquid humate.
| Application | How to use | Rate |

Frequently Asked Questions
Powder or crystal at 60%?
Both are 60% humic and ~99% soluble. Powder blends finest and dissolves fastest but dusts; crystal is cleaner to handle. Pick by your setup.
Is 99% soluble enough?
For most blends and pond use yes; a trace residue is normal. For zero residue use the 100% shiny flake.
Can it be blended with urea or DAP?
Yes, at 5–10 kg per tonne through the normal cycle; separation during transport is minimal.
Can it go in ponds?
Yes — dissolve and spread; it binds ammonia and clarifies water. Dose by pond volume.
Do you provide a COA per batch?
Yes — tested humic acid, 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.
