Our take on the Sequestar 13.2% Fe EDTA Iron Chelate

Sequestar 13.2% Fe EDTA is a water-soluble iron chelate powder from Brandt, made for correcting iron chlorosis in crops, nursery stock, greenhouse plants and hydroponics. The EDTA chelation keeps iron available to roots and leaves across a pH range of about 4.0 to 6.5, which is wider than plain iron sulfate. It dissolves cleanly for foliar sprays, fertigation or reservoir dosing, so it fits most feeding programs. It suits growers who already manage pH and want a fast, targeted iron fix rather than a general-purpose fertilizer.

About the Sequestar 13.2% Fe EDTA Iron Chelate

Sequestar 13.2% Fe EDTA Iron Chelate is a water-soluble iron fertilizer in powder form. It is made for Brandt and supplies iron to plants. It is used to correct iron deficiency, including iron chlorosis and yellowing leaves.

The iron is chelated with EDTA, which keeps it available to plants in alkaline soils up to pH 6.5. The powder dissolves completely. It can be used for foliar feeding, fertigation, or in hydroponic systems.

It suits greenhouse, nursery, field and hydroponic growing. Crops include ornamentals, vegetables, fruits, turf and container production. It is also used where high pH soils or water sources limit iron availability.

Questions and answers

How is this different from iron sulfate?
The iron is chelated with EDTA, so it stays available to plants over a wider pH range instead of locking up quickly. Iron sulfate is cheaper but less stable in soil.
Will it work in alkaline soil?
It is effective up to about pH 6.5. Above that, the EDTA bond weakens and iron becomes less available, so a higher-pH chelate such as EDDHA is the better choice.
Can I use it in hydroponics?
Yes. It is fully water-soluble and can be added to reservoir or fertigation solutions, though it is best dosed to keep solution pH in the 4.0 to 6.5 range.
How do I apply it?
Mix with water for foliar spray, fertigation or root drench. Follow the label rates for your crop and avoid over-applying, since excess iron can damage leaves.
Can I tank-mix it with other fertilizers?
It is compatible with most fertilizer programs, but check each tank mix, especially with calcium or phosphate products, to avoid precipitation.
Where is the Sequestar 13.2% Fe EDTA Iron Chelate cheapest?
At Custom Hydro, for $29.65, as of our latest check.
