How can we distinguish Potassium humate and humic acid sodium ?
Jul 26, 2017

Potassium humate is an efficient organic fertilizer which is well-received in the market.

This product includes humic acid, which is a bioactivator. Its benefits are as follow:

1. Improves potash fertilizer utilization

2. Slows decomposition to increase the release of potassium

3. Improves work ability of soil

4. Stimulates crop growth

5. Improves stress tolerance of crops

6. Improves the quality of agricultural crops

7. Protects agricultural eco-environment.

8. It can also be compounded and dissolved with trace element, urea, Phosphate fertilizer, potash 

However, currently a lot of fake 100% water soluble potassium humate are on the market. They offer extremely low price to fight against formal product market. Customer’s feedback said that they have tested the content of humic acid and potassium in potassium humate and never found unqualified phenomenon. Confronting such abashed situation, GREENFERT research staff went deep into potassium fake market with the leading of market researchers. Finally, they got the following results: 

Why the price of potassium humate is greatly difference in the market?

The fundamental difference between genuineness and fake is different materials.

Technique used by genuinenessPotassium humate= humic acid + KOH

Technique used by fakeHumic acid sodium= humic acid + NaOH

Potassium humate= Humic acid sodium + KCL

The price of KOH is more than three times of NaOH, that’s the main reason for wide difference of price.


Customers just test the content of humic acid and potassium, so the lawbreaker get the opportunity. A large amount of sodium ions and chloride ions exist in the soil and plants, which has a bad effect on plant and soil environment.

A large amount of sodium ions may lead to alkaline soil and sodium soil. It may worsen physical and chemical properties of soil. Also, it has bad influence on plant growth. The more important thing is that it’s difficult to improve this situation if it happens.

A large amount of chloride ions may restrain plant growth and form chlorine poison, even lead to zero output soil. For example: chlorine crops are rejected by potatoes, cabbage, peppers, lettuce, apples, grapes, watermelons and some other crops.

Therefore, facing the fake, customers had better raise their vigilance. To facilitate customers distinguish the true from the false, the following test methods are delivered as a reference:

Step 1: If the content of Na is higher than 2% or CL is higher than 1%, the potassium humate is fake.

Step 2: If the content of insoluble matter is higher than 5%, it can not be regarded as 100% water solubility. So it’s fake.

GREENFERT organic fertilizer are made of centrifugal technology, and 100% water solubility can be ensured. Welcome consulting!
