HUMICRAFT® Liquid Brochure

Number: EINECS - 271-030-1
Number: CAS - 68514-28-3

Reference number (REACH):


HUMICRAFT® Liquid is a suspension with 10% potassium humate (from Leonardite), 10% potassium alginate (from Ascophyllum nodosum) and 10% amino acids. HUMICRAFT® Liquid is a water soluble high quality plant growth stimulant and soil conditioner. It can be applied for agricultural and horticultural plants, such as fruit trees, ornamentals, turf and pasture, by soil and foliar application. It is an organic complex and is decomposed only relatively slowly by soil microorganisms. It can be used alone or mixed with most fertilizers.


HUMICRAFT® Liquid contains humic acids which are obtained by alkaline extraction from German Leonardite (highly oxidized lignite), and seaweed extract, and further contains amino acids from hydrolyzed protein. It provides a very high content of humic and fulvic acids, alginic acid, amino acids and several biologically active micronutrients.


HUMICRAFT® Liquid  is a bioactive growth stimulant and soil conditioner with 10% potassium humate, 10% seaweed extract as potassium alginate, and 10% amino acids. This product is suitable for all agricultural and horticultural plants, particularly those suffering from environmental growth stresses such as heat, cold, salinity and dryness. It can enhance the performance of fertilizers and reduce input costs.

  • Stimulates plant growth
  • Increases root growth and resistance to root diseases
  • Increases the permeability of cell membranes in the roots and increases their nutrient uptake
  • Increases the germination of seeds and enhances development of radicles
  • Increases yield and improves the quality of the plant
  • Improves the soil structure and its water retention capacity
  • Increases and stimulates beneficial microorganisms
  • Enhances the cation exchange capacity (CEC) of the soil
  • Increases the effectiveness of fertilizers and reduces nutrient leaching
  • Acts as a natural chelator for micronutrients in alkaline soils and increases their availability to plants
  • Decreases stress by drought and/or application of plant Treatments
  • Reduces the residues of herbicides and toxic substances in soils
  • Delays the decomposition of ultraviolet-unstable agents

“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.”


Humintech is a biotech company based in Grevenbroich, Germany. We are primarily focused on the research, development and industrial production of humic matter and humic acids for the agricultural sector.  Our products find further use in the feed, pharmaceutical and construction industry, in veterinary medicine and for ecological purposes such as water purification and soil decontamination.
