Our take on the Dissolvine Iron DTPA Chelate – 55 lb
Dissolvine D-Fe-11 is a water-soluble iron DTPA chelate powder with 11.6% iron by weight, sold as iron sodium DTPA. It is a single-nutrient iron source for greenhouse and commercial fertigation programs, meant to be dissolved separately and added to a complete crop-specific nutrient mix. DTPA holds iron in solution across a wider pH band than simple iron sulfates, which is why it is a standard choice for hydroponics and soilless growing. The 25 kg bag suits recurring nutrient preparation and larger batches rather than small hobby gardens.
- 11.6% iron by weight as iron sodium DTPA
- Chelated iron stays available over a wider pH range than iron sulfate
- Water-soluble powder mixes into stock tanks
- Suits recurring, large-batch nutrient preparation
- Reference rates given for vegetables and flower crops
- Single nutrient only; not a complete fertilizer
- Bulk 25 kg bag is far more than a small grower needs
- Requires calculation and injector calibration
- Iron percentage must be confirmed from the package or lot analysis
- Concentrated stock must never touch roots directly

About the Dissolvine Iron DTPA Chelate – 55 lb
Dissolvine D-Fe-11 is a water-soluble iron DTPA chelate for greenhouse and commercial growing programs that need a separately measured iron source. It is supplied as iron sodium DTPA. It is not a complete fertilizer, so it is used as the iron component of a crop-specific nutrient program.
The technical sheet gives an iron content of 11.6% by weight, or 116 grams per kilogram. Use the analysis on the package or lot documentation when calculating additions. Dissolve the product separately before adding it to the nutrient tank, and never apply concentrated stock directly to roots.
In hydroponics and soilless fertigation, the manufacturer reference gives continuous iron concentrations of about 0.8 ppm for vegetables such as tomatoes and cucumbers. For flower crops such as roses, gerbera and carnations, it gives 1.4 to 2.0 ppm. These are reference programs, not universal feeding rates. For soil use, the reference recommends application below pH 7.5. When root-zone pH reaches 7.5 or higher, it recommends considering an EDDHA-type iron source.

Questions and answers
- What is Dissolvine D-Fe-11?
- It is a water-soluble iron DTPA chelate powder, supplied as iron sodium DTPA, with 11.6% iron by weight. It is used as the iron component of a complete nutrient program.
- How much iron does it contain?
- The technical sheet gives 11.6% iron by weight, or 116 grams per kilogram. Confirm the figure on the package or lot documentation before calculating additions.
- How do I calculate how much to add?
- Grams of product = desired iron in ppm × final US gallons × 3.7854 ÷ (10 × iron percentage). Use 11.6 for the iron percentage only when the package analysis supports it.
- What crops is it used for?
- The manufacturer reference cites about 0.8 ppm continuous iron for tomatoes and cucumbers, and 1.4–2.0 ppm for roses, gerbera and carnations. These are reference programs, not universal rates.
- How should I mix it?
- Dissolve it separately before adding it to the nutrient tank, then calibrate injectors and verify the final dilution. Never apply concentrated stock directly to roots.
- Is it a complete fertilizer?
- No. It supplies iron only and is meant to be part of a complete, crop-specific nutrient program. Account for iron already in your water and other fertilizers.
