Different Types of Potassium Humate Powder

85% Water Solubility Potassium Humate Powder is one kind of potassium salt humic acid, because of the different production processes without using centrifugal pulp cleaner and roller machine, the water solubility is weaker compared with potassium humate shiny powder. But because they are reacted with potassium hydroxide, humic acid is converted into a soluble form. So they have very high chemical and biological activity levels. What’s more, their lower cost is a large advantage. If you use them as base fertilizer and mix with Urea and other NPK fertilizer or Trace-element fertilizer, or broadcast or water flush .they have 100% effect same as 100% water solubility potassium humate fertilizer.

Function
Extend the fertilizer of urea, promote the absorption of nitrogen, and improve the utilization rate of nitrogen fertilizer.
Reduce the fixation of available phosphorus in the soil, promote the absorption of phosphorus by crops, and stimulate crop root development.
Reduce the fixation of potassium, promotes the release of insoluble potassium, and slowly release the adverse effects of potassium fertilizer on soil and crops.
Improve the soil aggregate structure, make the soil loose, and increase water absorption.
Influence on soil pH, organic matter, soil microorganisms, and enzyme activity, improve soil physical and chemical properties and improves soil biological activity.
improve crop drought resistance, drought resistance, and the prevention and control of crop diseases and insect pests.
Promote seed germination, root system, and vegetative growth, and regulate plant metabolism.
Improve the content of sugar and vitamin C in fruits, and improve the quality of vegetables, fruits, and other crops.
