HUMINSEED® Liquid consists of a suspension with bioactive humic acids and fulvic acids. As a water-soluble, high-quality plant growth and germination conveyor, HUMINSEED® Liquid 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.


HUMINSEED® Liquid is obtained by alkaline extraction from German Leonardite (highly oxidized soft brown coal) and from aquatic fulvic acids. These have been created by geological and chemical processes and biological humification of organic material. HUMINSEED® Liquid contains a very high content of both humic and fulvic acids as well as trace elements. 


HUMINSEED® Liquid important plant enzymes are immediately stimulated and thus increase the germination rate. The powerful root formation increases the nutrient uptake capacity. The plants thus strengthened are much less susceptible to diseases. 

  • Stimulation of metabolic activity
  • Stimulation of plant enzymes
  • Stronger root formation
  • Increase nutrient uptake
  • Increase of germination rate and germ growth 


The best results with HUMINSEED® Liquid are obtained when the seeds are treated with a humic acid solution between 24-72 hours before sowing. E.g.: Grains, cucumbers, and beans can be dipped for 24 hours in a dilution. Solution consumption for seed treatment is 0,5- 1 litres per 100 kg of seeds.

HUMINSEED® Liquid is added into the solution last. It is recommended to apply the working solution on the day of its production.

* This recommendation may be varied according to the soil characteristics and local conditions.
