    Earthworms and iron...???

    Just found this kind of interesting and was curious if others find the same.
    Most any time I dig iron, there are worms in the plug.
    Aluminum, no worms.
    Seems like there was s a connection.
    All I could find was a study showing the worms had a receptor for the earths magnetic field,
    That allows them to know up from down.
    I realize there are plenty of worms in the ground, but it seems like every iron target is surrounded with them.
    Curious

    Iíve wondered about that plus weeds and other plants with a head start in spring. Seems like there is always a patch of weeds or greener grass when Iím digging a target. Almost like the metal is warmer than the surrounding ground so the plants above it have a competitive advantage. Worms and ants also seem to be in higher abundance. This is purely non-scientific.

    I cannot offer any science, except to agree that iron targets I dig have earthworms, in the plug. Occasionally, there are grub worms, but I toss those out for the robins. I’ve noticed, for some time, that black ants are frequently nested over an iron target. I wonder if the decayed iron has loosened the soil, making it easier for the worms, or ants, to burrow; or does it provide some nutrient for them.

    Interesting observation, I will have to keep this in mind as I dig.

    I believe it has to do with the nutrition iron provides.
    A friend's grandfather used to throw rusty iron into his garden, he had best garden around.

    If it's old, I'll dig it, dive on it, detect it or sometimes when I get lucky just bend over and pick it up.

    Iron and mild steel rust is in the sulfur neighborhood. (Iron oxide.) Not a match but close enough for thermite properties for example.
    There is a kind of bacteria involved in the corrosion.
    Is it a beneficial one to certain critters?

    Want green grass?
    Spray liquid iron on your lawn.
