Potassium Humate Fertilizer Function
Potassium humate is a highly effective organic fertilizer, because humic acid is a high active agent, can increase available potassium in soil, reduce the loss and fixation of potassium, increase crop potassium absorption and utilization,also can hold the nitrogen and slow release,unclock the phosphorus inside the soil ,chelate the micro elements, improve the soil structure to increase its water holding capability and create good environment for microbial group ,which will also help to improve the soil structure.Accordingly the soil fertility will be greatly increased and increased plants growth and harvest and its fruits quality.
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 fertilizerManufacturing process
1.raw material
1.1 Select leonardite or lignite
1.2Natural oxidization for more than 3month
1.3Crushing into fine powder
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.
Pump the dilution after sedimentation into centrifugal constantly to get high purity humate liquid.
5.1Flake type through rolling drying machine
5.2Powder type through spray tower.
5.3Solar drying into crystal form
