HUMIRON® Mix WSP is a concentrated, water-soluble fertilizer with trace elements based on bioactive potassium humates (activated humic matter) and trace elements. The main components are bio-active humic acids combined with iron (Fe), zinc (Zn) and manganese (Mn), in a chelated plant available form. HUMIRON® Mix WSP can be used to prevent and correct trace element deficiencies in crops. The humic acids present in HUMIRON® Mix WSP increase the resistance against abiotic stress (drought, salt, heat, etc.). 

HUMIRON® Mix WSP is suitable for both soil and foliar applications and can be combined with other fertilizers and pesticides (pre-mixing test advised).


  • Corrects nutrient deficiency symptoms (Fe, Zn, Mn) in the cultivation
  • It is a natural, economic source of trace elements compared to traditional synthetic chelated sources which often contain excessive sodium
  • Increases fertilizer use efficiency and plant productivity
  • Increases tolerance of plants against abiotic stresses such as drought, salt, cold and heat
  • Increases the water holding capacity of soils and reduces nutrient leaching  
  • Provides available forms of Fe, Zn and Mn for direct uptake by plants either through the leaves or root systems without prior conversion
  • Activates soil life and encourages beneficial cycles in the soil
  • Decreases stress from drought and/or application of pesticides

“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.”
