FeED THE CROP,

NOT JUST THE

DEFICIENCY

By: JR Peters

When iron starts to slip in a fertility program, it doesn’t whisper—it shows up in the crop.
New growth pales, interveinal chlorosis creeps in, and suddenly high-value crops like
petunia, calibrachoa, pansy, and mum stop looking like themselves. And in a market where
“finish” is everything, there’s no time to chase symptoms after they appear.

For years, many growers leaned on Sprint as a reliable iron correction tool. With Sprint
no longer available, that gap isn’t just a formulation issue—it opens the opportunity for
rethinking nutrient delivery. Growers don’t just need “an iron source.” They need a system
that holds iron steady, keeps nutrition complete, and doesn’t force constant intervention.

That’s exactly why Jack’s FeED formulas were built to step in.

A Jack’s FeED isn’t positioned as a rescue product. It’s a whole program itself— complete fertility with a designed-in iron strategy that holds. At the center of
that strategy is a chelated iron base composed of three sources: EDDHA, DTPA, and EDTA. This isn’t redundancy for the sake of complexity—it’s coverage.
Each chelate operates in a different pH window, and together they extend iron availability from roughly pH 4.5 to 9.0. Just as importantly, these chelated iron
sources were selected for their 100% solubility and stability in solution. Unlike iron sulfate or black iron materials that can leave sediment or create cloudy
nutrient solutions, EDDHA, DTPA, and EDTA chelates dissolve cleanly and remain available in solution. That means fewer injector issues, cleaner stock tanks,
and more consistent iron delivery to the crop.
