Product Description
JINGFENG HUMIC ACID is one of leading China suppliers of high-quality Potassium Humate, extracted from China Leonardite.
Super potassium humate is water soluble humic acid with 70% / 65%min humic acid and 10%min K2O. Its raw material is leonardite. Have types of flakes,powder,crystal and column. Completely soluble in water.
As the symbol of potassium is K, sometimes we call it K humate.

Dosage
- Use super potassium humate flakes as the humic acid raw materials to produce water soluble fertilizer contains NPK or microelement, the proposed dosage is 5-10%.
- Base fertilizer: Use super potassium humate granule like crystal or column for root fertilization, supply potassium element, plenty of organic matter to soil, help to improve soil condition.10-20 kgs per 666m2. Can improve drought resistance ability, cold resistance, disease and insect resistance
- Water flush: 5-10kgs per time per 666m2. Dissolve evenly into fertilizer tank to make potassium humate liquid solution. Generally apply fertilizer during seedling stage, growth period, flowering phase and fruiting period, total 4-5 times.
- Soaking seed, soaking root: Dissolve into water to make 1:2000 concentration potassium humate liquid solution. Soak 10-24 hours.

FAQ
When determining potassium humate containing fulvic acid, does the content of humic acid include the content of fulvic acid?
Is the fulvic acid (FA) a kind of humic acids (HA)? When determining potassium humate containing fulvic acid, does the content of humic acid include the content of fulvic acid?
In the current detection process of potassium fulvic acid in China, a question is often encountered: Is fulvic acid humic acid? Can it be considered that Fulvic acid is a kind of humic acid?
First, we make the following discussion from a dialectical point of view:
Assuming that fulvic acid (FA) is humic acid (HA), it can be considered that FA is contained in HA.
Mr.Cheng Shaoxin (formerly a member of the expert group of the Chemical Fertilizer Professional Committee of the China Chemical Industry Society, a director of the China Humic Acid Industry Association and a member of the Peat Humic Acid Professional Committee of the China Coal Society. He retired in November 1999 and has been participating in the firm until now. HA technology consultant, director of the Association of Old Technology Workers and provide voluntary consultation for relevant domestic HA companies.) The representative work "Introduction to Humic Acid Substances" mentioned: HA can be divided into three categories according to solubility, namely black HA, brown HA (ulmic acid) and FA. Then it can be understood that FA is HA, and when determining HA, FA can not be excluded. At present, the universally recognized humic acid classification and naming system in China and abroad was proposed by Romania's Kononova, as shown in the following table:
Soil organic matter
1,Non-humus--Fresh and inadequately decomposed animal and plant residues
2,Humus (a)Humus Substances:Including black HA, FA , humin and hymatomelanic acid.
(b)Non-humus Substances: the strong decomposition products of biological residues and products re-synthesized by microorganisms, including proteins, carbohydrates, waxes, resins, fats, tannins, lignin and their decomposition products, etc.
It can be judged from this table that HA includes FA acid in China and abroad.
Assuming that fulvic acid (FA) is a single substance, and humic acid (HA) is a separate substance, it is necessary to exclude each other when testing the two.
(1) According to the agricultural potassium humate testing standard GB/T33804-2017, extract the soluble humate from agricultural potassium humate with water at a certain temperature and then use a certain amount of acid to acidify the drawer to a certain pH value. After that, filter with medium-speed quantitative filter paper, wash the precipitate with a certain amount of water, a small amount of times and dry the precipitate in a drying oven to a constant weight. After weighing, subtract the ash to calculate the soluble HA content.
This standard uses the properties that fulvic acid is soluble in acidic solutions, neutral solutions, acetone and ethanol solutions. The fulvic acid dissolved in water is excluded during the analysis and only the substances precipitated with acid are used. It shows that this standard supports that fulvic acid and HA are two separate substances.
(2) It is mentioned in the standard HGT5334-2018 of the Ministry of Chemical Industry for potassium fulvate that, the fulvic acid in the sample is extracted with water and then the HA is precipitated with acid, and the supernatant liquid dissolved in the acid solution is the fulvic acid solution. .
This standard excludes HA when testing fulvic acid, likewise supports that fulvic acid and humic acid are two separate substances.
