HUMICRAFT® WSG is a water soluble, organic fertilizer based on potassium humates (activated humic acids), algae extract and amino acids. HUMICRAFT® WSG has a growth-promoting effect on roots and supports nutrient absorption with the help of humic acids. The algae extract (Ascophyllum nodosum) promotes rapid development of plant tissue. Amino acids taken up by the root are directly available to the plant as building blocks for protein biosynthesis. This saves energy for the plant, which it can utilise in other metabolic processes such as yield formation and abiotic stress compensation. In addition, plant amino acids serve as a nitrogen source. 

HUMICRAFT® WSG can be applied using fertigation, hydroponic and sprinkler systems as well as conventional foliar sprays. (Pre-mixing test recommended).


  • Stimulates plant growth, increases yield and improves the quality of the plant 
  • Facilitates the plant's energy balance
  • Increases and stimulates the population of beneficial microorganisms and activates soil life
  • Increases the tolerance of plants against abiotic stress (drought, salt stress, cold and heat)
  • Reduces the residues of herbicides and toxic substances in soils
  • Increases the effectiveness of fertilizers and reduces nutrient leaching, especially nitrates
  • Increases seed germination and enhances free radicle development
  • Strengthens root development and increases yield

“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.”
