Potassium fulvate contains both humic acid and fulvic acid, is mainly extracted from lignite. As it possess good water solubility, strong resistance to hard water, meanly used for spray irrigation,drip irrigation.

Other trade names: potassium fulvic acid, k fulvate, Resisting hard water potassium humate, deflocculation potassium humate or non-flocculating potassium humate, super potassium f humate.

Sulfonated potassium humate

Main Function

  1. Chelate macro and micro nutrients to make them better absorbed by plants.
  2. Prevent and control plant diseases and enhance waterlogging resistance.
  3. Stimulate the microscopic biological activity of plants.
  4. Slow-release fertilizers to improve the utilization of chemical fertilizers and pesticides.
  5. Improve nutrient absorption and promote plant germination and growth.
  6. Accelerate precipitation and decomposition, improve soil structure.

Usage of Potassium Fulvate

Fertigation and Foliar
 Nitrogen50-100 grams / hectare for each unit of Nitrogen applied as UAN, Urea,SOA
 e.g.2.3-4.6 kg/ha with 100 kg/ha of Urea
  e.g.2.1-4.2 kg/ha with 100 litres of UAN
  e.g.1.0-2.1 kg/ha with 100 kg/ha of SOA
 Salt-water0.5-1 kg/ha with each and all irrigation applications
 Salt-Soil Mitigation0.5-1 kg/ha with each and all irrigation applications
 Soil Improvement0.5-1 kg/ha with each and all irrigation applications
 N.B.This product is not compatible used in concentration with solution pH under 4.
For combination with elements or chemicals solution which pH is under 4, select fulvic acid.
