Which is better for iron chlorosis on alkaline soil?

Ferriplus. Its iron is chelated with FeEDDHA and it is formulated for soils above pH 7.5, up to a listed range of 8 to 12. Jack's MOST is a general trace blend with no stated iron content or pH range.

Is Jack's MOST a substitute for chelated iron?

Not directly. It supplies several trace elements, which helps when chlorosis comes from a mix of deficiencies. If iron is the confirmed problem, Ferriplus gives a known 6% chelated iron dose.

Yes. Jack's MOST is marketed as an additive to a fertilizer program, so it can be used alongside a targeted iron treatment. Avoid over-applying trace elements by following each label rate.

Which lasts longer in the soil?

FeEDDHA chelates are known for staying available in alkaline soil, which is Ferriplus's advantage. Jack's MOST gives no chelate details, so its soil persistence is unknown.

Is the price difference worth it?

The gap is 44 cents: $27.43 for Ferriplus versus $26.99 for Jack's MOST as of November 6, 2026. Pick by the deficiency you have, not by price.

Can Ferriplus be sprayed on leaves?

Yes. The label lists foliar spray as well as soil application, band placement, side dressing and fertigation. Jack's MOST is described only as water-soluble for mixing.
