Haifa Micro Fe DTPA 11% Chelated Iron Fertilizer

Haifa Micro Fe DTPA 11% supplies DTPA-chelated iron to help prevent and correct iron deficiency in plant nutrition programs. This water-soluble micronutrient fertilizer is offered in a 25 kg bag for growers managing iron nutrition in acidic to neutral growing conditions.

Targeted iron nutrition

Iron supports chlorophyll formation, cell division and plant growth. Iron deficiency can appear as yellowing between the veins of young leaves. DTPA chelation helps keep iron available for plant uptake, making this product a concentrated iron source for a carefully managed fertilizer program.

  • 11% iron: Concentrated Fe-DTPA for targeted iron supplementation.
  • DTPA chelation: Helps maintain iron availability in acidic to neutral conditions.
  • Water-soluble microgranules: Brownish solid microgranules for solution preparation.
  • 25 kg bag: Approximately 55.1 lb net weight.

These values are published by Haifa for its 11% Fe-DTPA product, Haifa Micro Top Iron S. The chelate stability range is a technical property, not a recommended crop root-zone pH range.

Use and mixing

Select application rates using the current product label, crop requirements, source-water analysis and existing iron levels in your fertilizer program. Do not carry over the potassium contribution or application schedule from the discontinued Fe-K DTPA formulation. This listing does not claim potassium content or sodium-free composition.

Use nutrient or laboratory analysis to assess iron concentration. An EC reading measures overall conductivity and cannot determine iron ppm on its own. Follow the current label and SDS for mixing, protective equipment, storage and handling.
