Potassium humate vs humic acid: what is the difference?
Potassium humate is soluble humic acid. Here is how the two differ, what grades like 49% and 98% mean, and which to use.
The difference
| Humic acid | Potassium humate | |
|---|---|---|
| Solubility | Low in water | High in water |
| Typical forms | Granules, powder | Powder, flakes, liquid |
| Best for | Basal soil application | Drip, drench, foliar, formulation |
| Our grades | Humic acid 51% granular, 5% powder, 1.5% granules | Potassium humate 49% powder |
What 49% and 98% mean
The percentage on a label describes content, but different labels measure different things: humic acid content, total humic and fulvic content, or solubility. That is why a '98%' product and a '49%' product cannot be compared on the number alone. In India, sell and buy the grade exactly as specified in Schedule VI. Our listed grade is potassium humate 49% powder.
How potassium humate is used
- Dissolved for drip and fertigation
- Soil drench around the root zone
- Mixed into liquid fertilizers and biostimulants by brand owners
