60% Sodium Humate Crystal
The High-Active Crystal — 60% Humic, Near-Total Solubility
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% Sodium Humate Crystal is the high-active crystal grade, guaranteed 60% humic acid on a dry basis with 99% water solubility. The crystal form dissolves almost completely, leaving only a trace residue, so it suits liquid humate, foliar and high-value blends that need a high humic number with a clear solution.
Step up to this grade when the 50% powder is not enough and you still want near-total dissolution.

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 (this product) | 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
High-active grade for liquid humate, foliar and premium blends.
| Application | How to use | Rate |
|---|---|---|
| Liquid humate / foliar | Dissolve and use as the humate base of liquid feeds or foliar sprays. | As required |
| Drip / fertigation | Pre-dissolve and meter in — near-total solubility, no line clogging. | 0.5–1.0 kg/mu |
| Aquaculture water | Dissolve and spread in ponds to bind ammonia and clarify water. | 1–2 kg/1000 m³ |
| High-value blend | Blend into premium fertilizer where a high humic number is required. | 5–10 kg/t |
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 crystal is stable for 2 years; reseal opened bags to keep moisture low.

Frequently Asked Questions
Crystal or 50-60% powder?
The crystal carries 60% humic and 99% solubility versus 50% and 85% for the powder — more active and cleaner, at a higher price.
Is it fully soluble?
About 99% — only a trace residue, so no filter step for most uses. For zero residue use the 100% shiny flake.
Can it go in ponds?
Yes — dissolve and spread; it binds ammonia and clarifies water. Dose by pond volume.
What is the humic guarantee?
≥ 60% on a dry basis, stated on every batch COA.
Do you provide a COA per batch?
Yes — tested humic acid and pH against Chinese industry standards.
What is the minimum order and lead time?
Stock item. MOQ one pallet; 7–15 days ex-works. Private-label printing available.
