    Howdy all,
    Hey, I like using fe but I shy away from non-liquid apps. because of the staining. I have used granular blends with iron sucrate before that don't stain concrete. I know that it is not as effective as iron chelate, but it still seems to help, I think. My Lesco rep says iron sucrate does absolutely nothing, but look good on the label.
    Have any of you used iron sucrate? What results did you get? Anyone know of a state Ag school that has tested it with chelated iron?

    IMHO Suricate does help Microbe population. However the amount of Suricate on Fe alone is so small that their is very little effect. The purpose of the suricate is for slow release of the Iron.

    A few years ago I read a university report that Iron Oxide is now believed to have better response than previously believed. I have found that it is the combination of elements that give the best response. I use Chelated Iron in a spray cocktail and get quick response that last 6 to 8 weeks. Spraying or Granules alone is not the best program. A combination of both might be.

    I think on Bermuda lawns you will see a different. But a St. Aug u want see as
    big of different. I would just experiment and see what works. Like Ric said u
    have to try it for yourself u may figure out a cocktail that works for u.
  4. To the three above post:

    Why are you applying the iron?
    to correct soil defiency?
    to help with stress?
    to make turfgrass greener? with less N?

    Here's why I apply iron.

    1. I have a lot of sandy soils and I do see fe deficiency.

    2. N causes more growth than fe, we mow about 1/3 of our spraying accounts, with the bulk of the balance being mowed by the homeowner so the more I can curb the post application growth spurt.

    3. I get a darker, richer green w/ fe than I do with N, Ph, Pk alone.

    What I'm really after with this thread is trying to find a non-staining granular fe that really works. I do 3 liquid apps and 3 granular apps/year and i want to include fe in those too, but I don't want to blow every walk, drive, curb and stone.

    I read a couple of articles that talked about iron sucrate favorably. I only used a little of it myself, but it seemed to work well.

    Iron sucrate is popular because it doesn't stain concrete as badly as Iron oxide. This is probaby why it doesn't make grass green.

    To have any impact on cool season turf the Nitrogen to Iron ratio should be 4:1 (or greater) which almost no one offers. Likewise the iron has to be available which in my experience the sucrate is NOT.

    Ric, do you have a link to that Edu oxide study? I'd like to see it.

    It has been as least 3 years ago when I read that. Sorry I no long remember where to even start looking. I have been the Ferrous Sulfate route and have no desire to return to it. I am currently using Chelated Iron 12-0-0 6% Fe 4% Mn and buying it in 55 gallon drums at under $ 4.00 a gallon.

    That's what I use,with my liquid apps. Have you found a pump that works well and stands up to the corrosive nature of that stuff, I went through 2 last year.

    We use sprayable Iron Sulfate up here to kill moss without harming the turf.

    I need a decent supplier of bulk granular iron for later this year when we put a new plant online. The thing is we need to be sure we're sourcing material that actually WORKS. LOL

    Liquid chelates WORK!

    Ever tried Sprint 330? Sweeeeeet.
