Humic Acid and Humates

1.What is Humic Acid?
There are lots of humic acid products on the marketing, but only a few people know exactly what humic acid is or how it is formed. Actually, humic acid is the remains of animals and plants, mainly the remains of plants, through the decomposition and transformation of microorganisms, as well as a series of chemical processes and accumulation, and the formation of a class of organic substances.
New-Nutri Humic Acid is extracted from the leonardite, it’s the raw material of potassium humate, potassium fulvate, sodium humate, and other humate salts. It’s in black powder or granule form, the pH value is around 5, so the Humic Acid can be used as a soil conditioner on saline-alkali land and help to increase the yields.
2. How many kinds of Humic Acid?
Classified by molecular weight, it can be divided into three categories:
a) Hy-matomelanic acid, the part of humic acid soluble in alkali but insoluble in acid
b) Humus acid, the part of humic acid that is insoluble in neither alkali nor acid
c) Fulvic acid, the part of humic acid soluble in both alkali and acid
Among them, fulvic acid is the most active one, which has the best effect on increasing the yield of crops.
3. What’s the main function of Humic Acid in agriculture?
a) Improving soil. Improve soil structure, adjust PH value, improve saline soil, increase crop yield.
b) Improve the utilization rate of chemical fertilizers. Increase the absorption of NPK and reduce the volatilization of nitrogen.
c) Promote the development of crop roots and enhance photosynthesis.
d) Improve crops’ ability to adapt to harsh environments. The use of humic acid under bad conditions, such as insufficient water, unsuitable temperature, high soil salinity and excessive heavy metals, can help plants maintain a faster growth rate.
e) Improve the quality of agricultural products, make the stalks of crops strong, resist lodging, lush leaves, and increase the content of green leafy elements.
4. What’s the difference between Humic Acid, Alginic Acid, and Amino Acid?
5. The difference between potassium humate, sodium humate and humic acid compound fertilizer.
Mineral source potassium humate is an alkaline organic potassium fertilizer that can be dissolved in water. Not only does it have all the functions of humic acid, it also contains potassium. Because of its good water-solubility, potassium humate is more convenient to use and more popular with farmers. New-nutri Potassium Humate, which is OMRI listed, is one of the most popular products of our company, it has been exporting to many countries. Combining with the market demand, through different raw materials and different production processes, we produce a series of potassium humate products, including potassium humate granules, powder, flakes, crystals and potassium fulvate. Potassium fulvate contains plenty of fulvic acid with perfect water solubility.
Sodium humate, which has the same appearance as potassium humate, but it’s not suitable for plant and agriculture use, however, it’s very nice to be used as a feed additive for animals and aquaculture. Potassium humate and sodium humate can be identical in appearance, water solubility and PH value, but the production cost is quite different. Potassium humate is much more expensive than sodium humate. However, we found that there were bad merchants in the market purchasing sodium humate as potassium humate to make more profit. If you don’t know how to tell the difference, don’t worry, contact us and we’ll show you how.

Humic Acid compound fertilizer is a kind of fertilizer that combines humic acid with NPK fertilizers or medium and trace elements fertilizer. Because it contains humic acid, it greatly increases the utilization rate of fertilizer, making it more effective than normal fertilizers.

6. The price difference of humic acid products between the cheapest one and the most expensive one is 10 times, why?

This mainly depends on which kind of humic acid the product is and which kind of raw material is used.
Water-insoluble humic acid is very cheap and can be just used as a soil conditioner in agriculture.
Potassium humate which contains high fulvic acid is very expensive, but it’s very nice to be used as foliar fertilizer in the irrigation system with very high performance. Sometimes, in the whole growth cycle of crops only need to use 10-15 kg/Ha will have very good results. The water solubility of New-Nutri Potassium Fulvate(it’s also called potassium humate but contains 50% fulvic acid) is 100% without any sediment, it’s suitable used with many other chemical fertilizers include NPK and trace elements.
Bio Humic Acid is extracted from leftovers or molasses, its cost of raw material and production is low, so the price is cheap. But the mineral humic acid’s performance is much higher than bio humic acid.

7. Questions of Potassium Humate

If good quality potassium humate is shiny flakes? What’s the difference between it and sodium humate?
Good quality potassium humate must be shiny, but not necessarily flakes. New-Nutri Potassium Humate can be manufactured in many forms, such as powder, flakes, crystal, and granules, all of the above forms are shiny on good quality.
You can’t tell the difference between potassium humate and sodium humate just by looking at their appearance, their water solubility and the content of humic acid they have. You have to test the content of K2O or sodium to differentiate.
As far as we know, there are some agricultural chemical companies purchasing sodium humate in the market, but they thought it is potassium humate. Potassium humate, in addition to humic acid, contains potassium which is a nutrient necessary for plant growth, while sodium humate does not. If you have any problem with how to test them, please don’t hesitate to contact us, we will help you out.

After using potassium humate for your crops, don’t need anymore potash fertilizer?
The answer is no.
The content of K2O in New-Nutri potassium humate is around 10~12%, relative to the pure potash fertilizer, the content is still insufficient, so after the use of potassium humate, still need to apply other potassium fertilizer according to your crops’ growth requirements.

Why some potassium humate products anti – flocculation, some not?
The potassium humate used for leaf spraying requires a good water solubility. People usually first mix the solid potassium humate into liquid fertilizer. If there is sediment or flocculation, it can affect the effectiveness of the application, and sometimes even the atomizer or drip irrigation system can be blocked.
Anti – flocculation depends on the content of fulvic acid content of potassium humate. It contains high fulvic acid, then there is no flocculation.
