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.

Usage of Potassium Fulvate
|Fertigation and Foliar|
|Nitrogen||50-100 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-water||0.5-1 kg/ha with each and all irrigation applications|
|Salt-Soil Mitigation||0.5-1 kg/ha with each and all irrigation applications|
|Soil Improvement||0.5-1 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.
