Using Skimmate Sludge for Tree fertilizer?

[Treefer32]

O.k. so, at times I dry skim and get thick sludge in my skimmer. I might have been neglecting the skimmer cup itself and it may be over half full of dry thick sludge. I mean, it might have 2+ years of sludge in it.... Let's not talk about that, and instead talk about a tree... Yes a simple maple tree. I was told it needs lots of iron and nutrients and the soil may be poor in those things. Would depositing my skimmer sludge around the base of the tree be a bad thing, a good thing, or an indifferent thing. I've heard spreading marine shell fish shells and oil on lawns fuels positive bacteria in the soil that grass roots need to grow better. So, wondering if spreading 2 years worth of fish sludge would damage a struggling tree or help it? I put iron spikes in the ground next to it at least 2-3 times a year according to a local tree shop Maple trees will consume all the iron they can get their roots on. I didn't know if there's enough salt in skimmate to damage plants and/or trees?

Thanks for humoring my question!

Not sure it would help but I doubt it would hurt. Also not sure about having to add iron for maple trees. This is just a few in our front yard and nothing has ever been added to the soil but they grow just fine.

Why not get some products that are known to be safe and effective for what the tree needs? An analysis would probably go a long way toward figuring out if a nutrient or other deficiency is present, and if you have a university nearby they may have a plant pathology department that could take a look at some samples from the tree itself.

I'd be worried that the salt in it could damage the tree.

If you're looking into supplements for your tree, I'd look elsewhere. The "macro/micro" nutrients are probably helpful, but I wouldn't add salt to the soil, generally. A quick google snoop gave me this. If you had something that was used to the brine, maybe, but in this case, probably not the best idea, especially if your maple is struggling.

If salt was present in your skim, salt levels would routinely drop in your tank and require replenishment.
