Potassium Humate from Leonardite Humic Acid Organic Fertilizer

Potassium humate is an effective organic fertilizer, can increase utilization of potassium, slow release the nitrogen and release the phosphorus locked inside the soil thus to increase the soil fertility, can also improve the soil structure, promote crops growth, improve crop resilience, improve crop quality, protection of agricultural ecological environment. Potassium humate can also be used in oil drilling treatment agent, mainly from the effect to prevent borehole collapse.

Shandong Jingfeng Humic Acid Technology Co., Ltd. is high-tech company committing to humic acid R & D,producing and sales, was founded in 2009, in early 2015 the restructuring, the registered capital of 18 million, total assets of 200 million yuan, has more than 50 employees, including professional R & D 5 people.

The company is committed to humic acid products development,producing and sales. We have achieved remarkable results on development and application of the agriculture humic acid series,feed farming humic acid series,pharmaceutical grade humic acid, and also in ceramic industry,batteries and more. We are currently registered international certification in some foreign institutions.

Main products

Currently we have Agricultural Product series humic acid base fertilizer NPK, humic fertilization, macronutrients humic fertilization, fulvic acid foliage and the like; lead-acid batteries expansive aspect of high purity humic acid; sodium humate feed grade, pharmaceutical grade humic acid and so on 30 kinds of products.

What is humic acid?

Humic acid is a principal component of humic substances, which are the major organic constituents of soil (humus), peat, coal, many upland streams, dystrophic lakes, and ocean water.
It is produced by biodegradation of dead organic matter. It is not a single acid; rather, it is a complex mixture of many different acids containing carboxyl and phenolate groups so that the mixture behaves functionally as a dibasic acid or, occasionally, as a tribasic acid. Humic acids can form complexes with ions that are commonly found in the environment creating humic colloids. Humic and fulvic acids (fulvic acids are humic acids of lower molecular weight and higher oxygen content than other humic acids)are commonly used as a soil supplement in agriculture, and less commonly as a human nutritional supplement. As a nutrition supplement, free form (unreacted)

What is the basic function of humic acids?

1) Improve the structure of soil .For light and sand soil, it can retain water nutrient . For heavy and compact soil, working with fungi to create a crumb structure for better water oxygen and nutrients intake and improved root .

2) Adjust PH value of soil, it can neutralize both acidic and alkaline soil .

3) Stimulate plant growth, increase the yield and quality.

4) Reduce nitrate leaking into the groundwater and protect the underground water.

5) Increase the effectiveness of herbicide pesticide and fungicide, immobilize or reduce their harmful residues.

What is potassium humate?

Potassium humate is one of important humate acid salts,which is always called humate,is the final product when leonardite or lignite treated with alkaline.

What's the difference between humic acid and humate?

Humic acid has big molecule weight and not soluble in water,slightly soluble in alkalin solution.
Humate is salt of humic acid is complete soluble in water
In order to be soluble, humates in raw form such as lignite or leonardite must go through an alkaline extraction process. Any of the salts like potassium hydroxide, sodium hydroxide or ammonium hydroxide can be used as the extractant. The potassium hydroxide extracted form is preferred for fertilizing application as potassium hydroxide (the extractant) is acceptable to many of the organic registration bodies while sodium hydroxide and ammonium hydroxide are not. Due to the low use rate of soluble humates they are not used as a main source of potassium for crops. The potassium is only there as a result of the extractant used. We do not advise increasing the level of potassium beyond what is already in our product as it will raise the pH and place the product in the “Dangerous Goods” category for transport which is much more costly. If you require potassium for the crop we recommend using normal potassium sulfate applied with a 5% inclusion of Soluble Humate Granules.

Potassium humate Manufacturing process?

1.raw material

1.1 Select leonardite or lignite
1.2Natural oxidization for more than 3month
1.3Crushing into fine powder

2.Chemical reaction

2.1Supply raw material to reaction tank
2.2Treat humic acid raw material with alkaline (KOH) at certain ratio under high pressure and temperature,complete reaction.

3.Sedimentation

Transfer the dilution into first-sedimentation tank keep still for sometime separate humin and other impurities,then pump into second sedimentation tank.

4.Filtering

Pump the dilution after sedimentation into centrifugal constantly to get high purity humate liquid.

5.Three type of Drying

5.1Flake type through rolling drying machine.
5.2Powder type through spray tower.
5.3Solar drying into crystal form.
