HUMIRON® Fe WSP is a water-soluble organic trace element fertilizer based on bioactive potassium humate with plant available chelated iron. HUMIRON® Fe WSP can be used to prevent and correct iron deficiency symptoms in plants. In addition to supplying of chelated iron, the bioactive humic acids act as natural chelators, chelating trace elements in soils and increasing their availability to plants.

The humic acids contained in HUMIRON® Fe WSP increase the resistance of plants to abiotic stress factors (drought, cold, salt). HUMIRON® Fe WSP is suitable for soil and foliar application and can be applied in combination with fertilizer or pesticide (pre-mixing test advised).


  • Mitigates iron deficiency in cultivated crops 
  • Can be applied pre-actively or over the entire vegetation period if needed
  • Increases the stress tolerance of plants against drought, salt, cold and heat
  • Increases fertilizer efficiency and productivity
  • Economic source of iron compared to traditional chelated supplies
  • Increases the water holding capacity of soils and reduces nutrient leaching


  • General Farming
  • Vegetable Production
  • Fruit Production
  • Substrate Cultivates
  • Hydroponics
  • Lawn Care and Landscaping
  • Seed Treatment

“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.”
