HUMINSEED® WSP consists of a suspension with bioactive humic acids and fulvic acids. As a water-soluble, high-quality plant growth and germination conveyor, HUMINSEED® WSP is suitable for all agricultural and horticultural crops. The treatment of the seed with a humic acid solution stimulates the cell membranes as well as the metabolic activities and thus increases the germination rate.


  • Increases germination rates
  • Accelerates run-up of crops and cultivates
  • Improves early nutrient uptake by the roots
  • Stimulates metabolic processes and enzyme activities inside the germinating seed
  • Strengthens growth of radicles


  • Seed Dressing
  • Seed Pilling
  • Seed Priming


  • Seed Dressing 
    0.1% dressing agent to spray on the seeds with subsequent back-drying and sowing
  • Seed Pilling 
    0.01-0.02% solution into the pilling mass
  • Seed Priming 
    0.1% priming solution for soaking bath, subsequent back-drying and sowing

* These are standard-recommendations that can vary according to soil properties, plant cultivate and local system conditions.

“All Humintech humic substances based products are analysed according to the HPTA test method (ISO 19822:2018) to determine the content of humic and hydrophobic fulvic acids. Most suppliers are using the more simple “colorimetric” analysis method to determine the humic and fulvic acid contents, but experience shows that, due to its inaccuracy, this method indicates higher contents and is not suited to identify non humic substances such as lignosulphonates. In order to maintain the highest quality standard, Humintech has therefore decided to use the currently best analytical standard for the determination of humic and fulvic acids within the scope of quality control.”
