HUMIRON? Fe WSP water soluble iron humate is an iron micronutrient fertilizer containing 40% bioactive humic acids and 6% iron in chelated and complexed form. It is available for plants and can be used for prevention and correction of iron deficiency. It may either be used as a soil application or as a foliar spray. On soils, HUMIRON? Fe WSP can be applied by irrigation or injection directly into the soil. It can also be used in hydroponic culture. The presence of humic acids positively impacts on plant growth and health as well as on plants' resistance to stress.

HUMIRON? Fe WSP water soluble iron humate is obtained through extraction from German leonardite (highly oxidized lignite) with addition of a mineral iron salt. Besides iron it provides a very high content of humic and fulvic acids and natural biologically active trace elements. The raw materials of HUMIRON? Fe WSP are benign and guarantee an ecological first quality chelated iron product.

Iron plays a key role in formation of chlorophyll, a vital component for plant health. In cases of iron deficiency the plants suffer from interveinal chlorosis with leaves staining light green to yellow.

HUMIRON? Fe WSP water soluble iron humate is complexed and chelated with humic acids that make iron available for plants in a wide variety of problem soils. It can be used for prevention and correction of iron deficiency and can be applied to all agricultural and horticultural plants. It can enhance the performance of fertilizers, especially in saline soils, and it reduces input costs.

• Increases iron and nutrient uptake through the roots
• Economic source of iron as opposed to traditional chelated sources
• Direct uptake of iron, prior conversion not needed
• Rich in humic and fulvic acids, which protect iron and other micronutrients from oxidation
• Physically fixed in soils, improves water retention capacity and reduces leaching
• Environment-friendly
• Increases nutrient uptake
• Acts as a natural chelator for microelements in alkaline and calcareous soils
• and increases their availability for plants
• Decreases stress by drought and/or application of pesticides
• Reduces the residues of herbicides and toxic substances in the soil
• A natural product, in contrast to synthetic chelates, which often contain excessive amounts of sodium (e.g. some types of EDDHA)
