    Some of my plants are showing signs of iron and magnesium deficiency. I use no till soil, this is my first time having issues like this.

    There anything i could add to help them out?

    Ironite is a really nice "mineral mix" that is both fast acting and easily available at HD, Lowes and just about any garden shop. Just be sure to get the original mineral mix and not the fertilizer blends that have come out in the last few years that are intended for lawn applications.

    Neither of those will do anything for a Fe def.

    The only hard part with Ironite is finding it in like a 5lb bag. It's mostly in 20 or so lb bags. It really is very common and has been around for years, 40 that I'm sure of.

    Is that stuff organic?

    As organic as any mineral can be. Technically, no, since minerals don't contain carbon, but it is organic compatible, like the "organic" dolomite lime that got a laugh from me.

    It says it contains urea nitrogen and 'soluble' iron. Does that mean the iron has been chelated?

    Just curious,

    I dunno about this being organic. Someone correct me if I'm wrong.

    I'm sure it has been chealated for the fast release and what accounts for the 1-0-1 NPK.

    But, if you have a deficiency you may not want to wait a couple of months for the Fe in something like Greensand to release the Fe needed right now.

    It's up to the individual to use it or not. I use both greensand and azomite in my mixes, but both are slow release, long term deals. But, I also have no problem or concern using Ironite if a problem pops up. YMMV

    or is there not enough in it to help solve a Def?

    BTW OP are you sure you are dealing with Iron-?

    IDK just how much Fe kelp contains, but a kelp meal tea would certainly cover a lot of bases especially since the OP has some and if it's something other than iron.

    Good call !

    Kelp has 2.85mg iron per 100grams, thats almost 3%, which I think is significant. How much iron do plants need?
